The real deployments

A curated registry of paying-customer quantum workloads. We track who bought, what they're running, who they bought from, and how mature the program actually is.

A logo on a slide is a marketing milestone. A renewed purchase order is a deployment.

— the inclusion test for this registry

Most "quantum customer" lists are press-release composites — every Quantum Network member, every workshop attendee, every academic co-author. This one is narrower. Each entry below describes a specific workload, a specific vendor, and a contract the customer has elected to renew at least once. The status chip distinguishes Research (academic-track partnerships and grant-funded proofs), Pilot (production-adjacent, scoped budget, sponsor named) and Production (recurring spend integrated into the customer's planning stack).

We update the registry as deals expand, contract or move between statuses — and we remove names when a program is wound down. The point of the page is not to sell the sector. It is to give the reader a working answer to the question "is anyone actually using this stuff?" — and to make the answer specific.
