论文摘要
温度计的尺寸是量子温度学方案设计的关键。通常，有限维量子温度计的典型现象学不适用于无限尺寸。我们分析了非平衡高斯量子温度计的动力学和计量特征：一方面，我们强调量子纠缠如何增强复合高斯温度计的准备情况；另一方面，我们表明非平衡条件不能保证温度估计的最佳敏感性，因此表明对量子温度计的工作原理进行了重新评估。
The dimensionality of a thermometer is key in the design of quantum thermometry schemes. In general, the phenomenology that is typical of finite-dimensional quantum thermometry does not apply to infinite dimensional ones. We analyse the dynamical and metrological features of non-equilibrium Gaussian Quantum Thermometers: on one hand, we highlight how quantum entanglement can enhance the readiness of composite Gaussian thermometers; on the other hand, we show that non-equilibrium conditions do not guarantee the best sensitivities in temperature estimation, thus suggesting the reassessment of the working principles of quantum thermometry.
