ABSTRACT

Recent theoretical developments in information thermodynamics elucidated the link between the acquired information and the entropy production through measurement and feedback control by generalizing the fluctuation theorems and the second law of thermodynamics. We summarize here our recent experimental studies based on the colloidal system that have been conducted to test the theoretical findings of information thermodynamics. In particular, we present the design principles of error-free and noisy information engines consisting of a colloidal particle in an optical trap that is capable of performing nearly error-free measurement and ultrafast feedback control. Our perspectives on future experimental studies are also presented.

摘要

信息热力学的最新理论发展通过概括波动定理和热力学第二定律，阐明了通过测量和反馈控制获取的信息与熵产生之间的联系。我们在这里总结我们基于胶体系统的最新实验研究，该实验已经进行了测试信息热力学的理论发现。特别是，我们介绍了无错误和嘈杂信息引擎的设计原理，该引擎由光阱中的胶体粒子组成，能够执行几乎无错误的测量和超快速的反馈控制。还介绍了我们对未来实验研究的观点。
