Parallel distinguishability of quantum operations
Runyao Duan, Cheng Guo, Chi-Kwong Li +1
We find that the perfect distinguishability of two quantum operations by a parallel scheme depends only on an operator subspace generated from their Choi-Kraus operators. We furthe…

Common Resource State for Preparing Multipartite Quantum Systems via Local Operations and Classical Communication
Cheng Guo, Eric Chitambar, Runyao Duan
Given a set of multipartite entangled states, can we find a common state to prepare them by local operations and classical communication? Such a state, if exists, will be a common…
