Characterizing Operator Sum Representation of Discord Annihilating Quantum Channels
摘要
Abstract
In the note ,we give a characterization of operator sum representation of discord an‐nihilating channels .Furthermore ,we prove that a quantum channel Φis discord‐annihilating if and only if Φ⊗Id maps the maximum entangled state to a state with zero discord .关键词
