Description

We review the idea of fast-forward of adiabatic dynamics proposed by Masuda and Nakamura. This idea has been applied to diverse areas of physics. Here we show that the generation of entangled states is fast-forwarded and speeded up by application of a suitable driving protocol. Then we treat a dynamical system coupled with the dissipative environment. The fast-forward evolution of Gibbs state (: canonical distribution) is guaranteed by innovating the detailed balance condition for coefficients of the dissipator, which makes possible the existence of quantum analog of Carnot-like 4-stroke heat engine with arbitrarily finite power.
