摘要:

The attempt to gain a quantum speedup dynamics of an open system has triggered significant progress towards the search for faster and more efficient quantum information processing. In this report, we have proposed some methods of accelerating evolution speed of an open system by the controllable system or the controllable environments. By considering the exactly solvable and general environment models, it is shown that, no speedup evolution in the Markovian dynamics process can be transformed into quantum speedup evolution by the external driving of the system or by building new complex environment.
