论文摘要
使用半决赛编程中的技术，我们研究了找到最接近量子通道的问题，即在矩阵子系统上投影。我们得出了两个与Duan，Severini和Winter的量子LovászTheta功能相关的母系子系统的不变。
Using techniques from semidefinite programming, we study the problem of finding a closest quantum channel to the projection onto a matricial subsystem. We derive two invariants of matricial subsystems which are related to the quantum Lovász theta function of Duan, Severini, and Winter.
