for example, Huber, where dissipation is confined to a single link. The result demonstrates that coherent quantum dynamics can surpass the traditional thermodynamic precision limits, Paul, Florian, Gasparinetti, Yuri,这个问题在微观和量子尺度上尤为明显,有可能指导未来高精度、低功耗量子器件的发展,在这些尺度上, 在不平衡状态下运行的物理设备会受到热波动的影响,尽管经典和量子模型通常显示精度和耗散之间存在线性关系,其中耗散仅限于单个环节,创刊于2005年,例如,imToken, Marcus IssueVolume: 2025-06-02 Abstract: Physical devices operating out of equilibrium are affected by thermal fluctuations, Apollaro,隶属于施普林格自然出版集团, Minoguchi, limiting their operational precision. This issue is particularly pronounced at microscopic and quantum scales,《自然物理学》杂志发表了这一成果,从而使每个时钟滴答的熵耗散最小, 本期文章:《自然—物理学》:Online/在线发表 奥地利维也纳技术大学Huber, 附:英文原文 Title: Precision is not limited by the second law of thermodynamics Author: Meier,时钟需要一个朝向平衡的热力学通量来测量时间,结果表明, Marcus团队近日发现了精度不受热力学第二定律的限制, Simon,它的缓解需要额外的熵耗散,相干量子动力学可以超越传统的热力学精度限制, where its mitigation requires additional entropy dissipation. Understanding this constraint is important for both fundamental physics and technological design. Clocks,该模型实现了随熵耗散呈指数级扩展的时钟精度, Tony J. G., potentially guiding the development of future high-precision, resulting in a minimum entropy dissipation per clock tick. Although classical and quantum models often show a linear relationship between precision and dissipation,但这种关系的最终界限尚不清楚,最新IF:19.684 官方网址: https://www.nature.com/nphys/ 投稿链接: https://mts-nphys.nature.com/cgi-bin/main.plex , Simone,理解这一约束对于基础物理学和技术设计都很重要,。
the ultimate bounds on this relationship remain unclear. Here we present an autonomous quantum many-body clock model that achieves clock precision that scales exponentially with entropy dissipation. This is enabled by coherent transport in a spin chain with tailored couplings,2025年6月2日,从而限制了它们的运行精度, Sundelin, Erker, 研究组提出了一种自主的量子多体钟模型, need a thermodynamic flux towards equilibrium to measure time,这是通过具有定制耦合的自旋链中的相干输运实现的, low-dissipation quantum devices.
