无信号原理确定最佳量子态分辨

No-signaling Principle Can Determine Optimal Quantum State Discrimination

Joonwoo Bae, Won-Young Hwang, Yeong-Deok Han

摘要:

我们提供了一个利用无信号原理推导最小误差量子态鉴别中猜测概率的一般框架。我们表明,值得注意的是,猜测概率可以确定的无信号原理。这是通过证明,在半定规划的歧视,最优性条件对应的约束,量子理论不能用于超光速通信。最后,给出了猜测概率的一个一般界的封闭形式。

英文摘要:

We provide a general framework of utilizing the no-signaling principle in derivation of the guessing probability in the minimum-error quantum state discrimination. We show that, remarkably, the guessing probability can be determined by the no-signaling principle. This is shown by proving that in the semidefinite programming for the discrimination, the optimality condition corresponds to the constraint that quantum theory cannot be used for a superluminal communication. Finally, a general bound to the guessing probability is presented in a closed form.
