Water
No industrial water cooling disclosed. Quantum processors on site (Ocelot cat-qubit chip) operate in dilution refrigerators at near-absolute-zero temperatures, which use closed-cycle helium (helium-3/helium-4) rather than facility water for cryogenic cooling.

The California (CAISO) grid demand right now: 42.5 GW (EIA-930, 2026-08-26 00:00).

County water status: No drought in Los Angeles County, week of 2026-08-18 (US Drought Monitor). Data centers are large water users for cooling; this is the neutral local water picture.

Common questions

What is AWS Center for Quantum Computing Pasadena?
AWS Center for Quantum Computing Pasadena is an AI data center campus tracked on the DEPLOY registry, located in Pasadena, California, USA. DEPLOY records its capacity as a dated, sourced ledger: announced gigawatts versus actually energized gigawatts, never a press-release total.
Who is building AWS Center for Quantum Computing Pasadena?
Amazon Web Services is recorded as a party to AWS Center for Quantum Computing Pasadena on the DEPLOY registry.
Is AWS Center for Quantum Computing Pasadena operating yet?
As of the most recent verification on the DEPLOY registry, AWS Center for Quantum Computing Pasadena is energized and operating. DEPLOY tracks the lifecycle from announced through energized, so the current state reflects sourced evidence, not the original announcement.
How verified is the data on AWS Center for Quantum Computing Pasadena?
A human editor has reviewed this record for the indexed registry. Every capacity figure is an append-only, dated claim resolved to the highest-evidence tier; superseded claims are kept but excluded from the current view.
