ML-Powered FPGA-based Real-Time Quantum State Discrimination Enabling Mid-circuit Measurements
A preprint on arXiv describes an FPGA-based machine-learning classifier designed to identify superconducting qubit states in real time. The work targets mid-circuit measurement and conditional feed-forward, framing current superconducting readout as both latency-bound and error-prone compared with classical transistor-level state detection. The abstract stops short of reporting full system-level benchmarks, presenting the integration as a response to that readout gap.

If the FPGA implementation validates on current superconducting hardware with multi-qubit readout, it could be integrated into existing control stacks as a drop-in discriminator for MCM loops within two years.
