Dynamical quantum state tomography with time-dependent channels

In this paper, we establish a dynamical quantum state tomography framework. Under this framework, it is feasible to obtain complete knowledge of any unknown state of a d -level system via only one operator of a special type of positive operator-valued measure (POVM) in dimension d . We define a new...
