量子器件不兼容性的鲁棒性

Robustness of incompatibility for quantum devices

Erkka Haapasalo

摘要:

根据纠缠的鲁棒性,提出了一种量子器件不兼容性的鲁棒性度量。一般鲁棒性措施的概念,首先介绍了一般的凸几何设置和这些想法,然后应用到衡量如何不兼容的一对给定的量子设备。在三种特殊情况下计算了量子不相容性的鲁棒性:一对傅立叶耦合的秩-1锐观测量,一对可解码通道,其中可解码性意味着通道的左可逆性,以及一对由秩-1锐观测量和可解码通道组成。

英文摘要:

A robustness measure for incompatibility of quantum devices in the lines of the robustness of entanglement is proposed. The concept of general robustness measures is first introduced in general convex-geometric settings and these ideas are then applied to measure how incompatible a given pair of quantum devices is. The robustness of quantum incompatibility is calculated in three special cases: a pair of Fourier-coupled rank-1 sharp observables, a pair of decodable channels, where decodability means left-invertibility by a channel, and a pair consisting of a rank-1 sharp observable and a decodable channel.
