测量和反馈允许外部代理从与单个热浴接触的系统中提取功。单次测量所能提取的最大功和相应的反馈回路由测量所获得的信息给出,这一结果体现了信息论与随机热力学之间的密切关系。在本文中,我们展示了如何可逆地将布朗粒子限制在光镊势中,然后提取相应的自由能的增加作为功。通过反复跟踪粒子的位置并相应地修改势,我们可以获得最佳的功,即使在测量中有高度的不准确性。
Measurement and feedback allows for an external agent to extract work from a system in contact with a single thermal bath. The maximum amount of work that can be extracted in a single measurement and the corresponding feedback loop is given by the information that is acquired via the measurement, a result that manifests the close relation between information theory and stochastic thermodynamics. In this paper, we show how to reversibly confine a Brownian particle in an optical tweezer potential and then extract the corresponding increase of the free energy as work. By repeatedly tracking the position of the particle and modifying the potential accordingly, we can extract work optimally, even with a high degree of inaccuracy in the measurements.
