Real-time decoder for a MegaQuOp quantum computer using a single CPU
An arXiv preprint reports a real-time decoder for a MegaQuOp quantum computer that runs on a single CPU. The authors state that existing decoding efforts have focused on error-corrected memory or small numbers of logical operations, rather than end-to-end real-time decoding at million-gate scale. The abstract does not specify the error-correcting code, hardware, or error model used.

If the reported result holds, it could ease the classical control bottleneck for early fault-tolerant quantum processors, allowing labs to run million-gate error-corrected circuits with commodity CPUs rather than custom decoding accelerators.
The work claims real-time decoding on a single CPU for MegaQuOp-scale operations; prior decoders typically handled memory or limited logical operations, so removing a custom-hardware requirement would simplify system integration in near-term fault-tolerance demonstrations.
