An Architecture for Real-Time Quantum Error Correction with Neutral Atoms

arXiv:2611.15104v1 Announce Type: new Abstract: The latency of quantum measurement and classical decoding constrains the execution of adaptive fault-tolerant circuits. In neutral-atom processors, this requirement couples spatially resolved fluorescence detection to classical inference. Here we implement cascaded readout and decoding in a heterogeneous architecture that overlaps acquisition and processing at two spatial scales. Field-programmable gate arrays process camera rows as they arrive, while graphics processors decode an acquired logical block during acquisition of the next. This heterogeneous architecture offers flexibility in the choice of error-correcting codes and decoding algorithms.
