摘要

在本论文中，我们研究了德西特空间中引力代数的非平衡波动。这项研究的一个重要方面是量子测量理论，它使我们能够通过两点测量方案获得观测变量的动态波动。利用这一形式主义，我们建立了特定的波动定理。此外，我们还利用测量理论与量子信道之间的关系，证明量子信道由子因子表示。我们还对使用琼斯的子因子理论实现量子信道进行了评论。

Fluctuation theorems, quantum channels and gravitational algebras

In this note we study nonequilibrium fluctuations in gravitational algebras within de Sitter space. An essential aspect of this study is quantum measurement theory, which allows us to access the dynamical fluctuations of observables via a two-point measurement scheme. Using this formalism, we establish specific fluctuation theorems. Additionally, we demonstrate that quantum channels are represented by subfactors, using the relationship between measurement theory and quantum channels. We also comment on implementing a quantum channel using Jones’ theory of subfactors.
