Quantum correlations and coherence between two particles interacting with a thermal bath
(IOP Publishing, 2017-05)
Quantum correlations and coherence generated between two free spinless particles in the lattice, interacting with a common quantum phonon bath, are studied. The reduced density matrix is solved using the Markov approach. ...
QUASIDISTRIBUTIONS and COHERENT STATES FOR FINITE-DIMENSIONAL QUANTUM SYSTEMS
(Springer, 2011-07-01)
In recent years, an approach to discrete quantum phase spaces which comprehends all the main quasiprobability distributions known has been developed. It is the research that started with the pioneering work of Galetti and ...
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 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 ...
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 ...

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 ...
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 ...
Enhancement of Atom-Field Transfer of Coherence in a Two-Photon Micromaser Assisted by a Classical Field
(Natural Sciences Publishing Corp-nspNew YorkEUA, 2014)
Superintegrability of the Fock–Darwin system
(2017-08-01)
The Fock–Darwin system is analyzed from the point of view of its symmetry properties in the quantum and classical frameworks. The quantum Fock–Darwin system is known to have two sets of ladder operators, a fact which ...
Coherent atomic oscillations and resonances between coupled Bose-Einstein condensates with time-dependent trapping potential
(2000-08-01)
The atomic tunneling between two tunnel-coupled Bose-Einstein condensates (BECs) in a double-well time-dependent trap was studied. For the slowly varying trap, synchronization of oscillations of the trap with oscillations ...
