Constructing mehod of 2-EPP with different quantum error correcting
... In this paper, we proposed a method to construct a 2EPP which consists of different quantum error correcting codes and by simulations investigated the performance of the 2-EPPs for a phase-damping channel. The proposed protocol showed improved fidelity and purification rate compared with an EPP from a ...

CALCULATING A MAXIMIZER FOR QUANTUM MUTUAL
... quantity is known as the Holevo-Schumacher-Westmoreland (HSW) Theorem. Here we consider in particular the problem of determining this maximizer in the case of the amplitude damping channel. It is known in general that the maximizing ensemble can always be assumed to consist of at most d2 pure states ...
