论文摘要
我们研究了纠缠破坏通道的零空间结构以及相关的应用。我们表明,跟踪零矩阵的每个操作员空间都是纠缠破坏通道的零空间。我们基于互补的通道行为和纠缠破坏通道无空间的量子通道的混合单位性测试。我们确定可以保证某些纠缠破裂渠道的私人代数存在的条件。
We investigate the nullspace structures of entanglement breaking channels, and related applications. We show that every operator space of trace zero matrices is the nullspace of an entanglement breaking channel. We derive a test for mixed unitarity of quantum channels based on complementary channel behaviour and entanglement breaking channel nullspaces. We identify conditions that guarantee the existence of private algebras for certain classes of entanglement breaking channels.
