Thermal baths as quantum resources: More friends than foes?
(IOP Publishing, 2015-11-06)
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 ...
Quantum coherence and criticality in irreversible work
(American Physical Society, 2020-08)
The irreversible work during a driving protocol constitutes one of the most widely studied measures in nonequilibrium thermodynamics, as it constitutes a proxy for entropy production. In quantum systems, it has been shown ...
Quantum coherence and speed limit in the mean-field Dicke model of superradiance
(2020-11-16)
Dicke superrandiance is a cooperative phenomenon which arises from the collective coupling of an ensemble of atoms to the electromagnetic radiation. Here we discuss the quantifying of quantum coherence for the Dicke model ...
Fluxo de coerência quântica para um qubit evoluindo sobre a ação de canais quânticos
(Universidade Federal de Santa MariaBRFísicaUFSMPrograma de Pós-Graduação em Física, 2016-08-23)
Quantum Coherence (QC) has a fundamental role in Quantum Mechanics (QM). It has
been studied since the emergence of QM. However, this quantum feature is easily destroyed
when a physical system interacts with the environment. ...
Remote state preparation of a photonic quantum state via quantum teleportation
(Springer Verlag Berlín, 2014-06)
We demonstrate an experimental realization of remote state preparation via the quantum teleportation algorithm, using an entangled photon pair in the polarization degree of freedom as the quantum resource. The input state ...
Quantum coherence and uncertainty in the anisotropic XY chain
(Amer Physical Soc, 2014-09-30)
We explore the local quantum coherence and the local quantum uncertainty, based on Wigner-Yanase skew information, in the ground state of the anisotropic spin-1/2 XY chain in a transverse magnetic field. We show that the ...
