Rigetti Computing deepens HPE and Pittsburgh Supercomputing Center partnership with NSF-backed TangleLab quantum testbed

Rigetti Computing, Inc. (Nasdaq: RGTI) has expanded its collaboration with Hewlett Packard Enterprise and the Pittsburgh Supercomputing Center to build TangleLab, a new hybrid quantum-classical supercomputing testbed powered by a Rigetti 9-qubit Novera quantum computing system integrated with a classical high-performance computing environment. The testbed is funded by a $5 million National Science Foundation grant under the NSF Advanced Computing Systems and Services program, with construction expected to begin at PSC’s new data center on September 1, 2026, and full operations targeted for 2027. The announcement builds on Rigetti’s existing strategic relationship with HPE, which the two companies frame as an effort to commercialise quantum-enabled HPC systems for research institutions, public sector organisations and enterprise users. For a Nasdaq-listed pure-play quantum company that is still generating limited recurring revenue, the significance sits less in the size of the award than in the pattern it reinforces: US federal science infrastructure continues to place named superconducting quantum systems inside multi-year hybrid computing testbeds, and Rigetti’s Novera continues to win those slots. The unresolved question is whether Rigetti can convert this stream of testbed placements into repeatable enterprise and government revenue at higher qubit counts before its listed peers reset the competitive baseline.

Why does the NSF-funded TangleLab testbed matter more than the headline five-million-dollar grant figure?

TangleLab is a small dollar award by federal computing standards, but the structural features attached to it matter for how investors should read Rigetti’s positioning. NSF has channelled the funding through its Advanced Computing Systems and Services programme under award number 2537076, and the release notes that the system directly addresses national investment and action priorities for Fiscal Year 2027, listed in memorandum M-25-34/NSTM-2 from the Office of Science and Technology Policy, including enabling advancement in quantum information science and artificial intelligence. In practical terms, TangleLab is being anchored inside PSC’s new data centre with a defined onboarding, training and research consulting programme, and PSC will allocate time on the system through a competitive proposal process, giving individual researchers dedicated use windows while allowing educators real-time access for teaching. That structure matters because it creates a persistent pipeline of academic and public-sector users who benchmark, publish and train on a Rigetti-branded quantum system inside an HPE-integrated hybrid environment. For a company whose commercial thesis depends on being embedded early in the national quantum-HPC stack, that installed footprint is a strategic asset that a one-off procurement contract would not deliver on its own.

Where does the 9-qubit Novera sit inside Rigetti’s product stack and what does that mean for TangleLab’s read-through?

Rigetti sells on-premises 9-qubit to 108-qubit quantum computing systems, positioned across the Novera and Cepheus product lines. The Novera 9-qubit QPU is designed to plug into a customer’s existing cryogenic and control systems, which makes it well suited for national laboratories, university centres and research programmes that already have infrastructure and want to add quantum capability incrementally. The Cepheus family, spanning 36-qubit to 108-qubit configurations, is based on the company’s proprietary chiplet architecture and ships with Rigetti’s own control electronics. Rigetti has stated it deployed the industry’s largest multi-chip quantum computer in 2026 with Cepheus-1-108Q, built from twelve 9-qubit chiplets tiled together, and it designs and manufactures chips in-house at Fab-1. In that context, TangleLab is a Novera-tier placement rather than a Cepheus-tier deployment, so investors should not conflate the two. The 9-qubit Novera has a clear job to do inside TangleLab, particularly around benchmarking hybrid quantum-classical workflows, but the larger commercial prize for Rigetti sits in higher-qubit Cepheus systems delivered into government laboratories and enterprise research programmes. TangleLab reinforces the Novera as the standard research on-ramp, which supports the Cepheus commercial motion, but it is not itself a Cepheus revenue event.

How does the expanded HPE collaboration reshape Rigetti’s route into enterprise high-performance computing?

The most strategically meaningful line in the announcement is arguably not the NSF grant, but the reaffirmation that TangleLab builds on Rigetti and HPE’s collaboration to commercialise quantum-enabled high-performance computing systems. Masoud Mohseni, Senior Distinguished Technologist and Director of HPE Quantum at HPE Labs, framed HPE’s role as bringing quantum processors, artificial intelligence and advanced networking into a unified hybrid environment so that researchers can develop, benchmark and optimise quantum-classical workflows. For Rigetti, the value of that framing sits in distribution. HPE has entrenched relationships across federal, defence, energy, life sciences and industrial HPC buyers, and quantum systems that co-exist inside HPE-integrated environments can be procured, operated and supported through channels that customers already understand. If HPE increasingly presents Rigetti’s superconducting quantum stack as a native option within its hybrid HPC offering, Rigetti gains a route to enterprise buyers that would otherwise require an independent commercial motion the company does not yet have at scale. The commercial question the current announcement does not answer is whether HPE will introduce additional Rigetti-anchored testbeds or reference deployments beyond TangleLab in the next twelve to eighteen months. That cadence, more than any single grant number, will decide whether the collaboration is a strategic distribution channel or a research partnership.

What does the competitive backdrop from IonQ, D-Wave, Quantinuum and IBM imply for TangleLab’s significance?

Rigetti’s TangleLab win lands into a listed-quantum sector that has become more crowded on both the technology and the funding side. IonQ has been building out its trapped-ion offering with an aggressive acquisition and partnership programme, D-Wave continues to advance its annealing-based Advantage systems, Quantinuum has been driving logical-qubit milestones, and IBM has expanded its superconducting-qubit roadmap and its India quantum hub. Against that backdrop, Rigetti’s positioning argument rests on two claims stated in the release. First, that superconducting qubits offer fast gate speeds, with Rigetti citing 50 to 70 nanoseconds per gate, which the company describes as roughly 10,000 times faster than trapped-ion systems and about 100 times faster than neutral-atom systems. Second, that its multi-chip chiplet architecture provides a clearer path to scale than monolithic designs. Neither claim is independently arbitrated in the TangleLab announcement, and the comparative metrics rely on Rigetti’s own characterisation. What TangleLab does provide is an additional public-sector reference that validates the Novera as a testbed platform and reinforces Rigetti’s superconducting narrative in a market where IBM’s superconducting roadmap remains the dominant reference point. The competitive weight of that reference will depend on how the testbed publishes benchmark results during 2027, and whether those results position Rigetti’s hybrid workflows credibly against IBM’s own hybrid quantum-classical infrastructure.

How should investors read the Benchmark Buy initiation against the current share-price and operating evidence?

The TangleLab announcement lands the same trading session that Benchmark initiated Rigetti with a Buy rating, and RGTI has been trading in a wide range with a recent Nasdaq intraday reference around the mid-teens per share, giving the company a market capitalisation broadly in the mid-cap band. Rigetti’s twelve-month price history has been volatile, and analysts have noted a wide spread of price targets across the sector, with retail attention continuing to move quantum names on incremental catalysts rather than earnings evidence. The strategic read is that a Buy initiation on a day of a federally anchored testbed announcement will reinforce sentiment, but the underlying commercial reset that would justify a durable rerating requires evidence that Novera and Cepheus deployments are converting into recurring cloud, hardware and services revenue at a scale that meaningfully addresses Rigetti’s operating cash-burn profile. The valuation may appear reasonable under a successful-execution scenario in which higher-qubit Cepheus systems win multi-year government and enterprise contracts, but the current market value still implies limited independent confirmation of near-term commercial delivery at that scale. A sustained rerating would likely require stronger operating evidence in future quarterly disclosures.

What execution tests will decide whether TangleLab converts to durable revenue and strategic optionality?

The next set of tests investors can track fall into a compressed timeline. The first is construction milestone execution, with PSC targeting a September 1, 2026 construction start and full operations in 2027. Any slip in either date, particularly the full-operations target, would compress the window in which TangleLab-generated benchmarks and publications feed back into Rigetti’s commercial story. The second is whether the HPE relationship generates additional named deployments beyond TangleLab, either in the US federal system or with international research computing centres. The third is Cepheus commercial traction, since the 108-qubit chiplet system is where Rigetti’s differentiated architecture claim is most exposed to competitive review, and where recurring hardware-plus-services revenue would most clearly move the earnings profile. The fourth is Rigetti’s cash and financing posture, given that quantum hardware companies remain capital-intensive and the sector has seen several rounds of dilutive financing. Cross-referencing these four indicators over the next four to six quarterly disclosures should give investors a more disciplined framework for judging whether the TangleLab announcement is a leading indicator of a broader HPE-anchored commercial motion or a well-placed academic reference deployment that does not scale into enterprise revenue.

Key takeaways for Rigetti Computing and the TangleLab collaboration with HPE and the Pittsburgh Supercomputing Center

• Rigetti Computing will deliver a 9-qubit Novera quantum computing system to the new TangleLab hybrid quantum-classical testbed at the Pittsburgh Supercomputing Center, funded by a $5 million National Science Foundation grant under award 2537076.
• TangleLab construction is expected to begin at PSC’s new data centre on September 1, 2026, with full operations targeted for 2027, and PSC will allocate research time through a competitive proposal process alongside educator access, onboarding and consulting.
• The project reinforces Rigetti’s continuing collaboration with Hewlett Packard Enterprise to commercialise quantum-enabled high-performance computing systems, with HPE bringing quantum, artificial intelligence and advanced networking into a unified hybrid environment.
• The 9-qubit Novera is Rigetti’s research on-ramp product, distinct from its higher-qubit Cepheus 36-qubit to 108-qubit systems, which are based on the company’s proprietary chiplet architecture and were most recently represented by the Cepheus-1-108Q system built from twelve 9-qubit chiplets.
• Rigetti manufactures its chips in-house at Fab-1 and cites gate speeds of 50 to 70 nanoseconds as a superconducting-qubit performance claim, though comparative benchmarking against IBM, IonQ, D-Wave and Quantinuum sits outside the current release.
• The testbed award is strategically anchored, aligning with US federal Fiscal Year 2027 priorities in memorandum M-25-34/NSTM-2 from the Office of Science and Technology Policy, including quantum information science and artificial intelligence.
• The commercial revenue impact of the Novera placement is modest relative to Rigetti’s operating profile, so the read-through depends on how the HPE relationship expands into additional deployments and how Cepheus commercial traction develops.
• The announcement lands with Benchmark initiating Rigetti with a Buy rating on the same trading session, adding a sentiment layer that may reinforce near-term share-price attention while the operating-evidence base still develops.
• Investors should track construction milestone execution, additional HPE-anchored deployments, Cepheus commercial contracts and Rigetti’s financing posture over the next four to six quarterly disclosures as the tests that will determine whether TangleLab is a leading indicator or a standalone reference deployment.
• The unresolved question is whether Rigetti can translate its federally validated testbed footprint and HPE distribution optionality into durable recurring revenue before competitive pressure from other listed and unlisted quantum architectures resets the commercial baseline.

The near-term test is whether Rigetti’s next quarterly disclosure and the September 1, 2026 construction start reinforce a broader HPE-linked commercial cadence, or whether TangleLab remains a well-placed research reference without a visible enterprise pipeline behind it.
