Rigetti, HPE, and Pittsburgh Supercomputing Center Partner to Build “TangleLab” Hybrid Testbed

Rigetti, HPE, and Pittsburgh Supercomputing Center Partner to Build “TangleLab” Hybrid Testbed Quantum computing developer Rigetti Computing (Nasdaq: RGTI) has partnered with Hewlett Packard Enterprise (HPE) and the Pittsburgh Supercomputing Center (PSC)—a joint center of Carnegie Mellon University and the University of Pittsburgh—to construct TangleLab, a hybrid quantum-classical supercomputing testbed. Funded by a $5 million grant from the National Science Foundation (NSF) under its Advanced Computing Systems & Services program (Award #2537076), the facility will integrate a 9-qubit Novera™ quantum computing system with classical High-Performance Computing (HPC) and graphics processing unit (GPU) infrastructure. TangleLab expands upon Rigetti and HPE’s ongoing commercial collaboration to build quantum-enabled HPC systems. Designed to operate at PSC’s new data center, the testbed will leverage the gate speeds intrinsic to superconducting qubits (50–70 nanoseconds) to benchmark low-latency hybrid quantum-classical workflows, compiling routines, and workload orchestration across scientific research and AI applications.

Under PSC’s management, access to TangleLab will be allocated through a competitive proposal process balancing dedicated runtime for individual research projects with real-time access for university courses and educational workshops. To assist non-specialist users, the center will offer dedicated consulting, training, and onboarding programs. Construction at PSC’s new data center is scheduled to begin on September 1, 2026, with full operations expected in 2027. Project leadership brings together principal investigators across the collaborating institutions, including James Barr von Oehsen (Executive Director, PSC / Vice Chancellor, Pitt), Bruno Abreu (Deputy Scientific Director, PSC), Bruce Childers (Dean, Pitt School of Computing and Information), Masoud Mohseni (Director of HPE Quantum, HPE Labs), and Andrew Bestwick (Senior VP of Quantum Systems, Rigetti). The deployment integrates quantum hardware into classical cyberinfrastructure to address national research priorities outlined in OSTP Memorandum M-25-34/NSTM-2 for Fiscal Year 2027, serving as an open prototype for future enterprise quantum-HPC-AI system integration.
