Pegg-Barnett与Paul量子相位框架之间的形式关系

Formal relation between Pegg-Barnett and Paul quantum phase frameworks

Tomasz Linowski, Konrad Schlichtholz, Łukasz Rudnicki

AI总结:

本文通过证明结合量子受限放大器信道可将Pegg-Barnett形式精确推导出Paul形式的相位概率分布,建立了两种量子相位框架间的明确联系,表明Paul框架是Pegg-Barnett方法的半经典极限。

摘要:

定义厄米量子相位算符的问题几乎与量子力学本身一样古老。多年来,人们提出了许多解决方案,从抽象算符形式到相空间方法。在这项工作中,我们通过证明Paul形式中的相位概率分布可以精确地由Pegg-Barnett形式得出——即将后者与量子受限放大器信道相结合——从而在两种最突出的方法之间建立了明确的联系。我们的研究结果表明,Paul框架可以被视为Pegg-Barnett方法的半经典极限。

英文摘要:

The problem of defining a hermitian quantum phase operator is nearly as old as quantum mechanics itself. Throughout the years, a number of solutions was proposed, ranging from abstract operator formalisms to phase-space methods. In this work, we make an explicit connection between two of the most prominent approaches, by proving that the probability distribution of phase in the Paul formalism follows exactly from the Pegg-Barnett formalism by combining the latter with the quantum limited amplifier channel. Our findings suggest that the Paul framework may be viewed as a semi-classical limit of the Pegg-Barnett approach.
