AI总结:

该研究通过实验验证了玻色统计在增强麦克斯韦妖性能中的作用,展示了光子统计对热力学与信息理论的相互影响。

摘要:

麦克斯韦妖阐明了信息在热力学中的价值,通过测量和反馈:他将平衡气体转变为非平衡状态,从其中可以提取功。如果粒子遵循玻色-爱因斯坦统计而非可区分,则妖可以平均将系统进一步远离平衡。我们通过比较不可区分与可区分光子来实验支持这一近15年的预测。我们使用了一个完全可编程的线性光学平台,其局部光子统计最近已被证明具有热特性。妖非破坏性地测量子集模式中的光子数。根据结果,他有条件地交换测量和未测量模式。这种交换在特定子集模式与另一模式之间创造正温度差。平均而言,如果光子不可区分,则温度差更大。这一结果加强了关于热力学、信息和量子粒子统计之间相互作用的长期预测。此外,这项工作还表明了一种热力学方法,可以弱验证玻色采样平台。

英文摘要:

Maxwell's demon elucidates the value of information in thermodynamics, using measurement and feedback: he evolves an equilibrated gas into a nonequilibrium state, from which one might extract work. The demon can evolve the system farther from equilibrium, on average, if the particles obey Bose-Einstein statistics than if they are distinguishable. We experimentally support this decade-and-a-half-old prediction by comparing indistinguishable with distinguishable photons. We use a fully programmable linear-optics platform, whose local photon statistics were shown recently to behave thermally. Our demon nondestructively measures the number of photons in a subset of the modes. Guided by the outcome, he conditionally interchanges the measured and unmeasured modes. This interchange creates a positive temperature difference between a mode in a particular subset and a mode in the other. The temperature difference is greater, on average, if the photons are indistinguishable. This result bolsters a long-standing prediction about the interplay among thermodynamics, information, and quantum particle statistics. Additionally, this work suggests a thermodynamic means of weakly validating boson-sampling platforms.
