This is not a demonstrated large error-corrected processor. Error behavior worsens at greater repeated-gate depth; the surface-code simulation assumes perfect erasure checks and restricted noise models.
Repeated logical error-correction cycles on larger hardware with imperfect checks and all operational errors included.

A fast dual-rail gate retains detectable errors Reported: D-Wave’s research team reports an approximately 500-nanosecond controlled-Z gate between two dual-rail cavity qubits. Supported observation: The Nature paper reports about 0.5% erasures per gate and residual Pauli errors below 0.1% in its characterization. Conditions: Two encoded qubits use superconducting microwave cavities and a transmon coupler. Residual errors are evaluated after detected erasures are removed; they must be read alongside the erasure rate. Characterization uses state tomography and interleaved randomized benchmarking. Larger-code comparisons are simulated. Not established: This is not a demonstrated large error-corrected processor. Error behavior worsens at greater repeated-gate depth; the surface-code simulation assumes perfect erasure checks and restricted noise models. Next evidence: Repeated logical error-correction cycles on larger hardware with imperfect checks and all operational errors included.
