IonQ Demonstrates Real-Time QEC Decoding at MegaQuOp Scale on a Single Apple M4 Max CPU
IonQ researchers Min Ye, Andrii Maksymov, and Nicolas Delfosse posted a paper to arXiv describing an end-to-end real-time quantum error correction decoding pipeline for large-scale trapped-ion machines. The decoder operated on a single off-the-shelf Apple M4 Max CPU using 12 cores and handled MegaQuOp-scale decoding workloads.

This could move real-time QEC decoding onto commodity CPUs for near-term trapped-ion demonstrations, removing custom FPGA or GPU hardware as a prerequisite for error-corrected experiments.
The demonstrated pipeline already processes MegaQuOp-scale workloads on one M4 Max, which is relevant to early logical qubit operations. The main remaining precondition is confirming that latency and throughput meet IonQ's actual trap operation schedules and integrating the decoder into the control software.
