Rigetti Computing said it will partner with HPE and Pittsburgh Supercomputing Center (PSC) to build the TangleLab supercomputing testbed. 

The PSC-based testbed, which is being funded by a $5 million National Science Foundation (NSF) grant, will feature a supercomputer powered by a 9-qubit Novera quantum computing system integrated with a classical high-performance computing (HPC) system.

This project builds on Rigetti and HPE’s collaboration to commercialize quantum-enabled high-performance computing systems. 

Together, Rigetti and HPE are aiming to advance hybrid quantum-classical workflows for research institutions, public sector organizations, and enterprises exploring the future of HPC.

“This system will benefit from the fast gate speeds that are intrinsic to superconducting quantum systems, a critical metric for high-performance hybrid quantum computing environments,” said Subodh Kulkarni, CEO of Rigetti. 

“Moreover, by collaborating with HPE, the global leader in HPC, we are in a strong position to deliver world-leading hybrid computing solutions — starting with TangleLab,” said Kulkarni.

Masoud Mohseni, senior distinguished technologist and director of HPE Quantum at HPE Labs, said that realizing the potential of quantum computing will depend on how effectively quantum processors integrate with high-performance computing, AI, and advanced networking. 

“HPE’s role in TangleLab is to bring those technologies together into a unified hybrid environment, enabling researchers to develop, benchmark, and optimize quantum-classical workflows while gaining critical insight into how future quantum-HPC-AI systems will operate at scale,” said Mohseni.

PSC will allocate time on the computer using a flexible competitive proposal process. The goal will be to allow individual researchers to use the system in a dedicated manner when needed, while educators will also have real-time access when teaching classes and workshops. 

To help users of TangleLab come up to speed regardless of their level of experience with quantum computing, PSC will offer onboarding activities, training, and in-depth research consulting.

Construction of TangleLab is expected to begin at PSC’s new data center on September 1, 2026, with full operations expected in 2027.
