From: Role of flow of information in the speedup of quantum evolution

The total amount of flow information ℵtotal between the time zero and the time Γt = 10 as a function of classical driving strength Ω for various values of phase ϕ with Δ = 0. (a) The memory time is small with Γtd = 0.2. (b) The memory time is intermediate with Γtd = 2.
