"identifying/ resolving quantum state errors in real time forces quantum operations to pause while classical hardware processes data... overcome using dual-decoder handling complex workloads simulating up to 408 logical qubits/ >31.5 million quantum operations with only 0.02% execution delay, operating entirely on single off-the-shelf CPU... classical decoding infrastructure need not scale exponentially alongside growing quantum processors, solving major engineering hurdle for fault-tolerant quantum computing"
