### 1\. Summary

The Pittsburgh Supercomputing Center (PSC), in partnership with Hewlett Packard Enterprise (HPE) and **Rigetti Computing (NASDAQ:RGTI)**, is constructing TangleLab, a hybrid quantum-classical supercomputing testbed funded by a $5 million grant from the National Science Foundation (NSF) under the Advanced Computing Systems & Services program (award #2537076) \[1\]. Construction began on September 1st, 2026, with full operational capability targeted for 2027, TangleLab represents a deliberate, federally backed effort to address a critical gap in quantum computing research: the integration of quantum processing units (QPUs) with classical high-performance computing (HPC) infrastructure \[1\]\[2\]\[3\].

The testbed integrates a Rigetti Novera 9-qubit superconducting QPU with HPE classical compute, storage, and networking systems, including HPE ProLiant Compute DL384 Gen12 and DL385 Gen11 servers, HPE Cray Storage Systems C500, and HPE Networking infrastructure \[1\]\[2\]\[4\]. Unlike standalone quantum computers, TangleLab is explicitly designed as an open platform for investigating hybrid quantum-classical workflows across the entire computational pipeline, from preprocessing and compilation to workload management and orchestration \[1\]\[3\].

The report's principal findings: **First**, TangleLab occupies a distinct and valuable niche within the U.S. quantum computing landscape: it is neither a large-scale quantum computer nor a purely classical supercomputer, but rather a dedicated testbed for understanding how quantum and classical resources can be effectively combined \[2\]\[5\]. **Second**, the project leverages PSC's three-decade legacy in heterogeneous computing, dating to 1991, positioning it as an institutionally credible operator for such an experimental system \[12\]. **Third**, while the 9-qubit quantum processor is modest by industry standards, the system's value lies not in qubit count but in its capacity to generate empirical data on systems integration, latency, error mitigation, and workflow optimization, and thereby inform the design of future quantum-enhanced HPC architectures \[5\]\[6\]\[8\].

**Fourth**, the commercial and strategic implications are significant but contingent. For Rigetti, TangleLab provides a federally validated reference implementation for its Novera QPU within an HPE-led HPC environment, potentially supporting future revenue streams from on-premises QPU deployments \[5\]\[7\]. For HPE, the project advances its hybrid quantum-HPC platform strategy and contributes to a quantum-ready product offering \[11\]. For the broader U.S. quantum ecosystem, TangleLab contributes to workforce development and offers an open, non-proprietary platform for benchmarking hybrid applications \[2\]\[4\]. **Fifth**, risks include the modest qubit scale constraining the range of demonstrable quantum advantage, the inherent technical complexity of integrating superconducting quantum hardware with classical systems, and the dependence on continued federal funding for sustained operation.

## 2\. Contextual and Scientific Background

### 2.1 The Quantum Computing Landscape

Quantum computing exploits the principles of quantum mechanics, particularly superposition and entanglement, to perform computations that are believed to be intractable for classical computers in certain domains. Quantum processing units manipulate quantum bits, or qubits, which can exist in combinations of zero and one states, enabling parallel exploration of computational possibilities. Anticipated application areas include quantum chemistry and materials simulation, cryptography, combinatorial optimization, and certain machine learning tasks \[19\].

The global quantum computing market is undergoing rapid expansion, though from a modest base. Market estimates vary considerably: one analysis placed the market at approximately $0.8 billion in 2025, projected to reach roughly $1.08 billion in 2026 \[17\]. Other sources project the market at $3.62 billion in 2025 growing to $5.09 billion in 2026 at a 40.5 percent compound annual growth rate. Longer-term projections suggest the market could exceed $16 billion by 2035 \[18\]. This variability in estimates reflects the early-stage nature of the industry and the substantial uncertainty surrounding the timeline to commercially viable quantum advantage.

Despite these projections, near-term quantum systems remain constrained by limited qubit counts, high error rates, and the absence of fault-tolerant quantum error correction at scale. Industry analysts have cautioned that systems in 2026 will struggle to offer sufficient logical qubits at meaningful logical error rates for practical applications \[10\]. This reality has driven increasing interest in hybrid quantum-classical architectures as an intermediate paradigm that leverages classical computing to compensate for quantum hardware limitations.

### 2.2 Hybrid Quantum-Classical Architectures

Hybrid quantum-classical computing represents a pragmatic response to the limitations of **noisy intermediate-scale quantum (NISQ)** devices. In this paradigm, quantum processors handle the portions of a computation that benefit from quantum effects, while classical processors manage preprocessing, compilation, error mitigation, postprocessing, and orchestration of the overall workflow. This division of labor is not merely a stopgap; many leading theoretical frameworks for quantum advantage presuppose hybrid operation, as quantum processors are unlikely to function as standalone computational engines in the foreseeable future \[19\].

The technical challenges in hybrid integration are substantial and span multiple layers of the computing stack \[20\]. At the hardware level, QPUs operate at cryogenic temperatures (typically below 20 millikelvin for superconducting systems), requiring specialized interfacing with room-temperature classical infrastructure. Latency between classical and quantum components is a critical performance parameter, particularly for iterative algorithms such as the **variational quantum eigensolver (VQE)** and the **quantum approximate optimization algorithm (QAOA)**, which require repeated classical-quantum communication. At the software level, challenges include the absence of standardized toolchains, the complexity of quantum circuit compilation and resource estimation, and the integration of quantum programming frameworks with existing HPC workload managers \[20\].

TangleLab is specifically designed to generate empirical data on these integration challenges. As PSC Deputy Scientific Director Bruno Abreu stated, the goal is to

> "Integrate quantum technologies into classical high-performance computing environments to enable hybrid quantum-classical workflows that can display flavors of quantum utility" 

The emphasis on "flavors of quantum utility" rather than definitive quantum advantage is significant: the project is framed as an exploratory platform for understanding how quantum resources can add value within HPC workflows, even in the absence of fault-tolerant quantum computation \[1\]\[2\].

### 2.3 PSC's Legacy in Heterogeneous Computing

TangleLab is the latest iteration of PSC's long-standing institutional commitment to heterogeneous computing. Founded in 1986 as a joint effort of Carnegie Mellon University and the University of Pittsburgh, PSC was one of the original five NSF supercomputing centers \[1\]. In 1991, PSC achieved a notable milestone by linking supercomputer-class machines to enable them to communicate and efficiently exchange computational tasks, a pioneering achievement in heterogeneous supercomputing \[12\].

PSC's experience in routing parts of computational problems to different processor types best suited to each task provides operational and intellectual capital directly relevant to TangleLab. The center's familiarity with workload management, systems integration, and the practical challenges of operating diverse computational resources within a unified environment reduces the execution risk associated with the project. PSC has also operated some of the world's largest shared-memory systems and deployed early massively parallel processing systems, further evidencing its capacity to manage complex, innovative computing infrastructure \[12\].

## 3\. Key Players and Stakeholders

### 3.1 Pittsburgh Supercomputing Center

PSC serves as the lead institution, principal grantee, and operational host for TangleLab. The center brings institutional infrastructure, including a new data center where the system will be housed, as well as decades of experience in operating HPC resources for the research community \[1\]\[2\]. Barr von Oehsen, PSC's Executive Director and Vice Chancellor for Research Computing at the University of Pittsburgh, serves as Principal Investigator. Bruno Abreu, PSC's Deputy Scientific Director, serves as a co-Principal Investigator \[1\]\[2\].

PSC's allocation model for TangleLab will employ a flexible competitive proposal process, enabling individual researchers to use the system in a dedicated manner and educators to access it for real-time teaching \[1\]. This dual research-education mandate reflects the NSF's broader emphasis on workforce development and the cultivation of a quantum-ready workforce \[2\]\[4\].

### 3.2 Hewlett Packard Enterprise

HPE provides the classical computing, storage, and networking infrastructure for TangleLab, including HPE ProLiant Compute DL384 Gen12 and DL385 Gen11 servers, HPE Cray Storage Systems C500, and HPE Networking equipment \[1\]\[2\]\[3\]. Masoud Mohseni, Senior Distinguished Technologist and Director of HPE Quantum at HPE Labs, serves as a co-Principal Investigator \[1\].

HPE's involvement is strategic and extends beyond component supply. The company has been actively building a hybrid quantum-HPC platform that integrates quantum systems with HPE Cray supercomputing infrastructure. In June 2026, HPE announced expanded collaborations with eight quantum technology companies to advance hybrid quantum-classical computing integrated with HPC and AI infrastructure \[11\]. TangleLab provides HPE with a real-world testbed for validating its hybrid architecture, developing integration expertise, and creating a quantum-enhanced HPC product offering that can be delivered to other organizations \[5\]\[11\].

### 3.3 Rigetti Computing

Rigetti Computing supplies the quantum component of TangleLab: a 9-qubit Novera QPU based on the company's fourth-generation Ankaa-class architecture \[1\]\[5\]\[8\]. Andrew Bestwick, Rigetti's Senior Vice President of Quantum Systems, serves as a co-Principal Investigator \[1\]\[2\]. The Novera QPU features a 3x3 array of tunable transmons with tunable couplers for fast two-qubit operations, plus a separate 5-qubit chip for single-qubit characterization \[8\]\[9\]. The system is fabricated at Rigetti's Fab-1 facility in Fremont, California \[9\].

TangleLab represents a significant validation opportunity. The company has been pursuing a strategy of placing Novera systems on-premises at universities and laboratories, having earlier sold a 9-qubit Novera QPU to the University of Saskatchewan \[5\]\[6\]. TangleLab extends this footprint into a major U.S. supercomputing center, providing a federally backed reference implementation that could support future upgrades, usage-based revenue, and more stable contract flow \[5\]\[7\]. Rigetti CEO Subodh Kulkarni characterized the project as enabling "a quantum-enhanced HPC product offering that can be delivered to other organizations going forward" \[3\]\[5\]\[6\].

### 3.4 University of Pittsburgh and Carnegie Mellon University

The University of Pittsburgh and Carnegie Mellon University are PSC's founding institutional partners. Bruce Childers, Dean and Professor at Pitt's School of Computing and Information, serves as a co-Principal Investigator \[2\]. Carnegie Mellon's leadership, including Vice President for Research Theresa Mayer, has publicly endorsed TangleLab as a platform for "defining the future of scientific computing while preparing the workforce that will bring these technologies into practice". These institutional affiliations provide access to academic talent, research expertise, and educational pipelines \[2\]\[4\].

## 4\. Technical and Operational Consideration

### 4.1 System Architecture

Superconducting systems of this class deliver gate speeds of 50 to 70 nanoseconds, a metric cited by Rigetti's CEO as advantageous for high-performance hybrid environments \[6\].

The classical infrastructure comprises HPE ProLiant Compute DL384 Gen12 and DL385 Gen11 servers, HPE Cray Storage Systems C500, and HPE Networking, all connected to the QPU \[1\]\[2\]\[3\]. The integration of GPUs within the classical infrastructure is particularly notable, as GPUs excel at demanding AI tasks and accelerated simulations, complementing the QPU's capabilities \[11\].

### 4.2 Operational Model

PSC will allocate time on the system through a flexible competitive proposal process, enabling dedicated researcher access alongside real-time educational use for classes and workshops \[1\]. Onboarding, training, and research consulting will be provided to users across experience levels \[2\].

### 4.3 Technical Challenges and Integration Considerations

**First**, the cryogenic operating environment of the QPU requires specialized interfacing with room-temperature classical systems, imposing constraints on signal routing, thermal management, and physical packaging. **Second**, latency between classical and quantum components is a critical performance parameter, particularly for iterative quantum-classical algorithms that require frequent communication.

**Third**, the software stack must bridge quantum programming frameworks with existing HPC workload managers and resource schedulers \[20\]. This requires the development of quantum-ready primitives within HPC workflows, including tools for circuit compilation, resource estimation, error mitigation, and result interpretation. **Fourth**, the calibration and characterization of the QPU must be integrated into the operational workflow, as superconducting qubits require regular tuning to maintain performance \[9\].

The available public documentation does not provide specific performance metrics for the integrated TangleLab system, such as end-to-end latency, quantum volume, or algorithmic benchmark results. These data points are not expected to be available until the system becomes operational in 2027\. The project's value proposition is therefore centered on the process of integration and the generation of empirical knowledge about hybrid system design, rather than on demonstrating a specific quantum advantage \[1\]\[5\].

### 4.4 Comparison with Other Quantum Testbeds

TangleLab occupies a distinct position within the U.S. quantum testbed ecosystem. The NSF's National Quantum Virtual Laboratory (NQVL) program has funded multiple quantum testbed projects, including a $4 million grant for a 10-node quantum network led by Stony Brook University \[13\]\[14\]. These NQVL testbeds focus on networked quantum systems and distributed quantum computing. TangleLab differs in its explicit focus on hybrid quantum-classical integration within a single supercomputing environment, rather than on quantum networking or standalone quantum computation \[1\].

The system's 9-qubit processor is modest compared with the 84-qubit Ankaa systems that Rigetti has developed for cloud access, and considerably smaller than the 100-plus qubit systems offered by competitors such as IBM and IonQ \[5\]\[6\]\[10\]. However, TangleLab's value does not lie in qubit count. The testbed is designed to generate operational data on systems integration, workflow optimization, and the practical challenges of embedding quantum resources within HPC environments, research questions that are largely orthogonal to raw qubit scaling \[1\]\[5\].

---

## 5\. Economic and Market Dynamics

### 5.1 Funding Landscape

TangleLab is funded by a $5 million NSF grant under the Advanced Computing Systems & Services program \[1\]\[2\]. This level of funding is modest relative to the broader quantum computing investment landscape. The NSF has allocated up to $50 million for quantum testbeds for each of fiscal years 2025 through 2029, suggesting that TangleLab is one of several federally supported quantum testbed initiatives rather than a flagship program \[13\].

The $5 million grant covers system construction and initial operations but does not constitute a long-term operational budget. Sustained operation beyond the grant period will likely require additional funding from NSF, institutional support from PSC's partner universities, or user fees. The available documentation does not specify the projected operating costs or the mechanisms for long-term sustainability.

### 5.2 Commercialization Pathways

TangleLab's commercial implications are most significant for Rigetti and HPE. For Rigetti, the project provides a federally validated reference implementation of the Novera QPU integrated with HPE HPC infrastructure \[5\]\[7\]. This validation could support future on-premises QPU deployments at other research institutions and enterprises. The project also positions Rigetti within the broader HPE quantum ecosystem, potentially facilitating future collaborations \[11\].

For HPE, TangleLab advances the company's hybrid quantum-HPC platform strategy \[11\]. The integration experience gained through TangleLab will inform HPE's product development and could lead to a quantum-enhanced HPC product offering that can be delivered to other organizations \[3\]\[5\]. HPE's broader strategy involves integrating quantum systems with HPE Cray supercomputing infrastructure, and TangleLab serves as a proving ground for this approach \[11\].

The commercial viability of hybrid quantum-classical systems remains uncertain. While market projections are optimistic, with some analyses forecasting the quantum computing market reaching $21.9 billion by 2035, these projections depend on sustained technical progress, the demonstration of practical quantum advantage, and the development of viable business models \[18\]. TangleLab does not directly address commercialization but rather generates the operational knowledge that could inform future commercial offerings.

### 5.3 Competitive Positioning

TangleLab competes, in a limited sense, with other quantum testbeds and with commercial quantum computing cloud services. However, its positioning as an open, federally funded research platform distinguishes it from commercial offerings. Researchers can access TangleLab without commercial pricing constraints \[1\]. This open-access model is consistent with the NSF's mission \[2\]\[13\].

The system's 9-qubit processor is not competitive with the largest commercially available quantum systems. However, TangleLab's value proposition is not computational power but rather the opportunity to study hybrid integration in a controlled, well-supported environment \[5\]. The system is designed to serve as "the prototype open platform for a future where quantum information processing and distribution are core elements of advanced cyberinfrastructure" \[1\].

## 6\. Regulatory Landscape

The regulatory landscape for quantum computing infrastructure in the United States is still developing, and TangleLab operates within a framework that is more notable for its emerging character than for its established specificity.

Export controls represent the most directly applicable regulatory consideration. Quantum computing hardware, particularly QPUs and related cryogenic equipment, is subject to U.S. export control regulations administered by the Bureau of Industry and Security (BIS) under the Department of Commerce. These controls are designed to prevent the transfer of sensitive quantum technologies to countries of concern. TangleLab's operation as a domestically hosted, federally funded testbed does not raise immediate export control compliance issues, but the broader regulatory environment may affect the future deployment of similar systems.

In the cybersecurity domain, federal legislation has been introduced to address quantum-related risks. The **Quantum Encryption Readiness and Resilience Act** (H.R. 4942) would direct the Subcommittee on the Economic and Security Implications of Quantum Information Science to submit reports on mitigating cybersecurity and national security risks posed by cryptographically relevant quantum computers \[16\]. The **National Quantum Cybersecurity Migration Strategy Act** has also been introduced to create a federal roadmap for protecting sensitive data from quantum-enabled threats \[15\]. These legislative efforts reflect growing recognition of the national security implications of quantum computing but do not impose specific requirements on research testbeds such as TangleLab.

Standard intellectual property and data governance frameworks for federally funded research infrastructure are applicable to TangleLab. Users of the system will be subject to PSC's standard allocation agreements, which likely address data ownership, publication rights, and attribution. No peer-reviewed source was identified that provides specific analysis of regulatory frameworks uniquely applicable to TangleLab beyond general precedent for NSF-funded computing infrastructure.

---

## 7\. Geopolitical and Strategic Dimensions

The geopolitical and strategic dimensions of TangleLab are modest in direct terms but significant in the broader context of U.S. quantum computing investments. The United States, China, and the European Union have all identified quantum information science as a strategic priority, with substantial public investments and coordinated national strategies.

TangleLab contributes to U.S. competitiveness in quantum computing by supporting workforce development, providing an open research platform, and generating empirical data that can inform future system design \[2\]\[4\]. However, the project's $5 million budget and 9-qubit processor are small relative to the scale of international quantum computing investments. China, for example, has invested billions of dollars in quantum research and has demonstrated quantum supremacy claims with its Zuchongzhi processor. The European Union's Quantum Flagship program has committed over €1 billion to quantum technologies.

The strategic significance of TangleLab lies less in its direct technical outputs and more in its role as an institutional capability-builder. By integrating quantum hardware into an established HPC center with a three-decade operational history, TangleLab develops the human capital, operational expertise, and institutional knowledge that will be necessary for larger-scale quantum-HPC integration in the future \[12\]. As von Oehsen stated, the project is aimed at "helping build the quantum-ready workforce the nation will need" \[2\]\[4\].

The project's strategic dimension is part of the broader U.S. quantum ecosystem rather than as a uniquely consequential national security initiative. The most directly relevant strategic consideration is the project's contribution to maintaining U.S. leadership in quantum information science, a priority that has been consistently articulated in federal policy documents and congressional legislation \[15\]\[16\].

## 9\. Strategic Recommendations

### 9.1 Recommendations for Corporate Strategists and Investors

Corporate strategists and investors should assess TangleLab primarily as an indicator of broader trends in quantum-HPC integration. The project validates the hybrid quantum-classical paradigm and demonstrates federal commitment to quantum infrastructure, but the commercial implications are medium-term at best \[11\]\[17\].

**First**, monitor TangleLab's operational outcomes as a leading indicator for the hybrid quantum-HPC market. The system's success in integrating quantum and classical resources will inform the technical feasibility and timeline for commercial hybrid offerings. Key metrics to track include end-to-end latency, ease of integration, user adoption rates, and the diversity of applications successfully implemented on the platform. These data points, when they become available in 2027 and beyond, will provide early empirical evidence on the viability of hybrid architectures \[1\]\[20\].

**Second**, assess Rigetti's positioning through the lens of TangleLab. The project provides the company with federally backed validation and a reference implementation within an HPE-led ecosystem \[5\]\[7\]. However, Rigetti's financial position remains precarious, with high cash burn and dependence on government funding. The TangleLab partnership strengthens Rigetti's narrative but does not fundamentally alter its near-term financial trajectory. Investors should distinguish between the strategic validation provided by TangleLab and the company's underlying operational and financial performance \[10\].

**Third**, evaluate HPE's hybrid quantum strategy in the context of its broader HPC business. TangleLab is one component of HPE's expanded quantum collaborations \[11\]. The company is positioning itself as the integrator of quantum resources within HPC environments, a strategy that leverages its existing Cray supercomputing business. Corporate strategists should assess whether this integration strategy can generate sustainable competitive advantage relative to cloud-based quantum services and alternative integration approaches.

### 9.2 Recommendations for Research Directors and Policymakers

Research directors and policymakers should view TangleLab as a valuable but limited component of the U.S. quantum research infrastructure. The project's primary value lies in its capacity to generate empirical data on hybrid integration and to develop human capital \[1\]\[2\].

**First**, prioritize the development of standardized benchmarks and metrics for hybrid quantum-classical systems. TangleLab provides an opportunity to establish community-agreed metrics for evaluating hybrid performance, including latency, fidelity, and algorithmic throughput. These benchmarks would facilitate comparison across different hybrid architectures and accelerate the development of best practices \[20\]. The absence of standardized metrics is a significant barrier to progress in the field.

**Second**, ensure that TangleLab's allocation process maximizes its research impact. The flexible competitive proposal process should prioritize proposals that address fundamental questions about hybrid integration, generate publicly available data and benchmarks, and train early-career researchers \[1\]\[2\]. The system's educational mandate should be operationalized through structured training programs, curriculum development, and partnerships with academic institutions \[4\].

**Third**, consider TangleLab's role within the broader NSF quantum testbed portfolio. The NQVL program has funded multiple testbed projects with different technical foci \[13\]\[14\]. TangleLab's emphasis on hybrid integration complements networked quantum testbeds and standalone quantum computers. Policymakers should ensure that the portfolio as a whole covers the full spectrum of quantum research needs and that lessons learned from TangleLab are disseminated across the testbed ecosystem.

**Fourth**, develop a long-term sustainability plan for TangleLab. The initial NSF grant covers construction and early operations, but sustained operation will require additional funding. Options include continued NSF support, institutional funding from PSC's partner universities, user fees for non-research commercial access, and partnerships with industry. A clear sustainability plan is essential to maximize the return on the initial federal investment.
