摘要

Quantum speed limit (QSL) time under noise has drawn considerable attention in real quantum computational processes.Though non-Markovian noise is found to be able to accelerate quantum evolution for a damped Jaynes-Cummings model,in this work we show that non-Markovianity will slow down the quantum evolution of an experimentally controllable photon system.As an application,QSL time of a photon can be controlled by regulating the relevant environment parameter properly,which nearly reaches the currently available photonic experimental technology.
