Evidence
OQC Tech page: "Our 32-qubit Toshiko device is deployed and securely accessible in datacentres in the UK, Japan and soon New York, as well as in a supercomputing centre in Spain." OQC Cloud page: current generation is OQC Toshiko with 32 addressable qubits. No 2Q RB percentage is published on those two pages; CESGA QMIO write-up on oqc.tech gives T1 = 54 μs median / T2e = 66 μs median rather than a 2Q fidelity.Try another pair
