Quantum speedup dynamics process in Schwarzschild space–time

Quantum speed limit time (QSLT) can be used to characterize the intrinsic minimal interval for a quantum system evolving from an initial state target state. We investigate QSLT of open in Schwarzschild space–time. show that, some typical noisy channels, Hawking effect accelerate evolution system. For entangled state, enhanced depolarizing, bit flip, and bit-phase flip channels as temperature increases, which are sharp contrast phase channel. Moreover, optimal entanglement exists other noise except channel, minimizes thus leads maximum
