Milestone note Jun 2026
First state acquisition of a cat-qubit quantum computer
Reached
Alice & Bob / GENCI (France) — France's HPC agency GENCI signed a public procurement (at VivaTech 2026) for an 18-cat-qubit Alice & Bob system — the world's first formal state acquisition of error-biased cat-qubit hardware, funded via France 2030's HQI (Hybrid HPC-Quantum) initiative. It will be installed at the CEA's TGCC center (Bruyères-le-Châtel) and hybridized with the Joliot-Curie supercomputer, accessible to researchers in 2027 — billed as the first early fault-tolerant QC (eFTQC) permanently sited in a European supercomputing center.
