In this article we argue that thermal reservoirs (baths) are potentially useful resources in processes involving atoms interacting with quantized electromagnetic fields and their applications to quantum technologies. One ...

We explore the ability of a qubit probe to characterize unknown parameters of its environment. By resorting to the quantum estimation theory, we analytically find the ultimate bound on the precision of estimating key ...

In this work, we present a new class of quantum states for applications in quantum metrology and quantum information, the states here named as “Even EPR” and “Odd EPR”. We present a review of the basic concepts of ...

The problem of quantum metrology in the context of a particular non-Markovian quantum evolution is explored. We study the dynamics of the quantum Fisher information (QFI) of a composite quantum probe coupled to a Lorentzian ...

In this work the concepts of quantum mechanics on a photon device are studied. The variation in its relative phase is obtained through of the variation in the optical path, whtih is controlled through the refraction index ...

We report a theoretical and experimental study on the role of indistinguishability in the estimation of an interferometric phase. In particular, we show that the quantum Fisher information, which limits the maximum precision ...

Precise probing of quantum systems is one of the keys to progress in diverse quantum technologies, includingquantum metrology, quantum information processing and quantum many-body manipulations. We consider athermometer ...

In this work, we studied entanglement and decoherence in neutrino oscillations from a quantum metrology perspective. A summary of the quantum eld theoretic description of neutrinos was done and the main quantum mechanical ...
