一组量子态的量子性

The Quantumness of a Set of Quantum States

Christopher A. Fuchs, Masahide Sasaki

摘要:

本文是对quant-ph/0302092的介绍。我们建议量化一组量子态的“量子”程度。集合的量子性是通过经典通信信道传输状态的最坏情况困难。这种测量的潜在应用出现在量子密码学中,在量子密码学中,人们可能喜欢使用对量子窃听最敏感的状态字母表,以及在实验室演示量子隐形传态中,有必要检查纠缠是否确实被使用。

英文摘要:

This article is an introduction to quant-ph/0302092. We propose to quantify how "quantum" a set of quantum states is. The quantumness of a set is the worst-case difficulty of transmitting the states through a classical communication channel. Potential applications of this measure arise in quantum cryptography, where one might like to use an alphabet of states most sensitive to quantum eavesdropping, and in lab demonstrations of quantum teleportation, where it is necessary to check that entanglement has indeed been used.
