Overview
- The companies announced the TangleLab collaboration on Monday, funded by a $5 million National Science Foundation grant that will support a hybrid quantum‑classical supercomputing testbed at the Pittsburgh Supercomputing Center.
- Rigetti will deliver a 9‑qubit Novera quantum processing unit to be integrated with HPE’s classical HPC systems so users can run, benchmark, and refine hybrid workflows in a shared facility.
- The announcement sent Rigetti’s stock up about 12% in intraday trading as investors reacted to the funding and partnership news.
- Construction of the PSC testbed is scheduled to begin September 1, 2026, with full operations targeted for 2027, and PSC will allocate time through a competitive proposal process with training and consulting for users.
- The move comes as Rigetti works to raise two‑qubit gate fidelity on larger machines — its Cepheus‑1‑108Q reports 99.1% two‑qubit fidelity with a company target of 99.5% by end‑2026 — and as the firm heads into an August 6 Q2 earnings report with Wall Street estimating roughly $5.09 million in revenue and continued reliance on grants and federal support.
