Python in the front, party in the Backline: compiling quantum workloads across CPUs, GPUs, and FPGAs
A preprint describes a compilation approach that takes Python-defined quantum workloads and targets a mix of CPUs, GPUs, and FPGAs, with the stated goal of meeting the low-latency demands of real-time quantum error correction. It positions the gap between accessible Python tooling and production fault-tolerant execution as a key bottleneck.

If the proposed compiler can deterministically map latency-critical decoder operations to FPGAs while using CPUs and GPUs for higher-latency tasks, it could enable live, low-latency error correction loops for small logical qubits within two years.
FPGAs offer cycle-deterministic execution, but hand-coding them is a barrier; a Python-frontend compilation flow would lower that barrier. The main precondition is that the generated FPGA pipelines meet real-time deadlines under actual decoder workloads, which the preprint has not yet demonstrated.
