  title={Estimation precision of the acceleration for a two-level atom coupled to fluctuating vacuum electromagnetic fields},
  author={Mengge Zheng and Baoyuan Yang and Zixu Zhao},
In open quantum systems, we study the quantum Fisher information of acceleration for a uniformly accelerated two-level atom coupled to fluctuating electromagnetic fields in the Minkowski vacuum. With the time evolution, for the initial atom state parameter θ 6 = π , the quantum Fisher information can exist a maximum value and a local minimum value before reaching a stable value. In addition, in a short time, the quantum Fisher information varies with the initial state parameter, and the quantum…

Quantum estimation of acceleration and temperature in open quantum system

In an open quantum system, we study the evolution of a two-level atom as a detector which interacts with given environments. For a uniformly accelerated two-level atom coupled to a massless scalar

Quantized scalar field in rotating coordinates

Second quantization of the free scalar field is carried out in rotating coordinates and the spectrum of vacuum fluctuations is calculated for an orbiting observer using these coordinates. Normal-mode

Nonuniqueness of Canonical Field Quantization in Riemannian Space-Time

We point out and discuss an ambiguity which arises in the quantum theory of fields when the background metric is not explicitly Minkowskian-in other words, when an external gravitational field, real

Kruskal Space and the Uniformly Accelerated Frame

The striking formal similarities between the diagram of Kruskal space in general relativity and that of the uniformly accelerated rigid rod in special relativity are shown to be the result of certain

Completely Positive Dynamical Semigroups of N Level Systems

We establish the general form of the generator of a completely positive dynamical semigroup of an N‐level quantum system, and we apply the result to derive explicit inequalities among the physical
