Approximation of quantum assemblages

Publication date: Available online 25 October 2019Source: Physics Letters AAuthor(s): Xiaojing Yan, Zhi Yin, Longsuo LiAbstractIn this paper, we derive a set of projectors on a large Hilbert space which can universally work for approximating quantum assemblages with binary inputs and outputs. The dimension of the Hilbert space depends on the accuracy of the approximation.
