受白噪声和损耗影响下的投影测量兼容性

Compatibility of projective measurements subject to white noise and loss

Pavel Sekatski

AI总结:

本文研究有限维量子系统中受白噪声和损耗影响的投影测量不兼容性,推导出测量集合在可见度 p 和效率 η 下变得兼容的充分必要条件。

摘要:

众所周知,当两个或多个量子测量存在缺陷时,它们可能失去不兼容性。对于有限维度 d 的量子系统,我们研究了所有受白噪声和损耗影响的投影测量的不兼容性。我们推导出这组测量在可见度 p 和效率 η 方面变得兼容的充分必要条件。

英文摘要:

It is well known that when two or more quantum measurements suffer from imperfections they may lose their incompatibility. For a quantum system of finite dimension d we study the incompatibility of all projective measurements subjected to white noise and loss. We derive a necessary and sufficient conditions for this set of measurements to becomes compatible in terms of their visibility $p$ and efficiency $η$.
