The site combines research offices, an in-house superconducting-circuit fabrication line, and a quantum \"data center\" of dilution refrigerators that house the processors at millikelvin temperatures. It produced the 53-qubit Sycamore chip (2019 quantum-supremacy claim) and the 105-qubit Willow chip announced December 9, 2024, which was the first processor to demonstrate below-threshold surface-code error correction. The August 2026 $32.5M purchase of 83,356 sqft at 147/153 Castilian Drive expanded the footprint to roughly 300,000 sqft alongside the existing 301 Mentor Drive lab and 6868 Cortona Drive lease.","keyFacts":[{"label":"Type","value":"Quantum AI R&D campus (not hyperscale data center)"},{"label":"Total footprint","value":"~300,000 sqft (83,356 sqft purchased Aug 2026 for $32.5M)"},{"label":"Quantum AI lab","value":"301 Mentor Drive — quantum hardware development + fabrication facility"},{"label":"UCSB partnership","value":"Quantum computing research partnership with UC Santa Barbara"},{"label":"Location","value":"Santa Barbara Research Park, Goleta, CA"},{"label":"Established","value":"2013, chosen for proximity to UCSB's superconducting-qubit talent pool"},{"label":"Primary chip","value":"105-qubit Willow superconducting processor, announced Dec 9, 2024"},{"label":"Predecessor chip","value":"53-qubit Sycamore (2019 quantum-supremacy demonstration)"},{"label":"Willow benchmark","value":"Random-circuit sampling in ~5 minutes vs 10^25 years on a classical supercomputer"},{"label":"Error correction","value":"First processor to demonstrate below-threshold surface-code error correction (errors decrease as qubit count scales)"},{"label":"Cooling","value":"Dilution refrigerators operating at ~10-20 millikelvin"},{"label":"Fabrication","value":"In-house superconducting-circuit fab with Josephson-junction patterning"},{"label":"Aug 2026 acquisition","value":"83,356 sqft at 147/153 Castilian Drive purchased for $32.5M from a Bloomsbury/ABC-CLIO seller"},{"label":"Other sites","value":"Leased space at 6868 Cortona Drive (~15,000 sqft) and lab at 301 Mentor Drive"},{"label":"Access program","value":"Willow Early Access Program for select research partners;
