Remote Quantum State Restoring and Approximation

Speaker: Alexander Zenchuk

Venue: Room 206, No.2 Haina Building, Zijingang Campus

Abstract: How to recover the quantum states sent remotely is an important research topic in quantum information theory. This report will introduce an important processing technique. Except possibly for the diagonal elements, the recovered quantum states are proportional to the corresponding elements of the initial states, and these elements satisfy the normalization condition. This method has important applications in the theory of quantum computing.
