Stroboscopic small-Big-small sequences with an auxiliary qubit stabilize cat and squeezed-cat manifolds, preserve bit-flip bias, and partially correct single-photon loss without reservoir engineering.
Evolutionary BP+OSD achieves higher decoding performance and lower complexity than standard BP+OSD on surface and QLDPC codes, especially under low-latency constraints.
Modified Quantum Volume test uses restricted universal circuits to directly determine heavy outputs without exponential classical simulation cost.
