量子平滑

Quantum smoothing

Masahiro Yanagisawa

摘要:

介绍了利用纠缠和连续测量估计量子初态的方法。本文给出了经典光滑和量子光滑的统一形式,并给出了一个光滑测不准关系。作为例子,示出了通过双模压缩态的两方之间的通信。

英文摘要:

Quantum initial state estimation through entanglement and continuous measurement is introduced. This paper provides a unified formulation of classical and quantum smoothing and shows a smoothing uncertainty relation. As an example, a communication between two parties via a two mode squeezed state is shown.
