New QMaxCal method enhances quantum control by minimizing decoherence effects

By PulseAugur Editorial · [2 sources] ·

Researchers have developed a new method called QMaxCal for open quantum control, which uses Girsanov's theorem to regularize path-space. This approach aims to minimize the effects of decoherence by penalizing observable consequences of control on decoherence channels, rather than control amplitude. The QMaxCal regularizers, including Wiener KL and drift-variance regularizers, have demonstrated superior performance over baseline methods in various open quantum systems, achieving up to a 50% reduction in infidelity and significant gains on a calibrated IBM Kingston processor.
