The site is where Rigetti brought its 108-qubit Cepheus-1-108Q system, built from twelve interconnected 9-qubit chiplets, to general availability on April 7, 2026, delivering 99.1% median two-qubit gate fidelity at roughly 60 ns gate speed via Rigetti QCS and Amazon Braket. A 9-qubit Novera system from this stack anchors TangleLab, the $5M NSF-funded hybrid quantum-classical testbed with HPE and the Pittsburgh Supercomputing Center scheduled to break ground at PSC on September 1, 2026. Cooling is dilution-refrigerator cryogenics (helium-3/helium-4 mixture at millikelvin), not water; grid power is served by PG&E in the CAISO footprint.","keyFacts":[{"label":"Technology","value":"Superconducting quantum computing (full-stack)"},{"label":"Products","value":"On-premises 9-qubit to 180-qubit systems"},{"label":"Ticker","value":"Nasdaq: RGTI"},{"label":"TangleLab","value":"Hybrid quantum-classical testbed with HPE + PSC ($5M NSF)"},{"label":"Lab lease","value":"Berkeley sublease through Nov 2029"},{"label":"Founded","value":"2013 by Chad Rigetti (former IBM quantum researcher)"},{"label":"Flagship","value":"Ankaa-3 (84 qubits) + Novera QPU (9 qubits)"},{"label":"Cash position","value":"$558.9M (Sep 2025)"},{"label":"CHIPS Act","value":"$100M funding"},{"label":"Roadmap","value":"150 qubits (2026), 1,000 qubits (2027)"},{"label":"Berkeley sublease size","value":"12,543 rentable sqft of office and lab space at 740 Heinz Avenue"},{"label":"Sublease counterparty","value":"Subleased from Chinook Therapeutics, Inc.
