论文摘要
使用两级移动探针，我们解决了由以热状态制备的无质量标量场建模的静态热浴的温度估计。在各种情况下，讨论了探测器与现场的不同耦合。我们发现温度计完全不受能量水平的羔羊移位的影响。我们考虑了探针速度的作用，其初始制备和环境控制参数，以实现最佳温度估计。我们表明，可以利用一种实用技术来实现这种量子温度法。最后，利用以高速度移动的热传感器在多参数估计策略内探测温度时，我们证明了关节估计的完美至上，而不是单个单个估计。
Using a two-level moving probe, we address the temperature estimation of a static thermal bath modeled by a massless scalar field prepared in a thermal state. Different couplings of the probe to the field are discussed under various scenarios. We find that the thermometry is completely unaffected by the Lamb shift of the energy levels. We take into account the roles of probe velocity, its initial preparation, and environmental control parameters for achieving optimal temperature estimation. We show that a practical technique can be utilized to implement such a quantum thermometry. Finally, exploiting the thermal sensor moving at high velocity to probe temperature within a multiparameter-estimation strategy, we demonstrate perfect supremacy of the joint estimation over the individual one.
