Scalable Error-Mitigated Quantum Telemetry for Superconducting Multi-Qubit Processors

By Prof. Alistair Vance , Dr. Elena Rostova

Superconducting quantum circuits face severe fidelity degradation due to thermal quasiparticles and decoherence during multi-qubit readout cycles. In this paper, we introduce an adaptive error-mitigation protocol that performs real-time continuous calibration using non-destructive dispersive telemetry. Benchmarked across a 127-qubit planar lattice, our approach suppresses state-preparation and measurement (SPAM) errors by 41.6% without incurring physical qubit overhead. Experimental verification on benchmark algorithms demonstrates two orders of magnitude improvement in circuit depth capacity.
