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 ...
Magnetic Otto engine for an electron in a quantum dot: Classical and quantum approach
(MDPI AG, 2019)
We studied the performance of classical and quantum magnetic Otto cycle with a working substance composed of a single quantum dot using the Fock-Darwin model with the inclusion of the Zeeman interaction. Modulating an ...
Geometry effects on the electronic properties of multi-open dots structures
(Ieee-inst Electrical Electronics Engineers Inc, 1998-11-01)
In this paper we show that the electronic properties of multi-open dots structures are strongly modified by even smalt changes in their geometries. Our discussion of these effects is done in terms of the interaction among ...
Quantum thermodynamics aspects with a thermal reservoir based on PT -symmetric Hamiltonians
(2021-08-01)
We present results concerning aspects of quantum thermodynamics under the background of non-Hermitian quantum mechanics for the dynamics of a quantum harmonic oscillator. Since a better control over the parameters in quantum ...
Quantum state transfer in disordered spin chains: How much engineering is reasonable?
(Rinton Press, Inc, 2015-05-01)
The transmission of quantum states through spin chains is an important element in the implementation of quantum information technologies. Speed and fidelity of transfer are the main objectives which have to be achieved by ...
Absolute Quantum Yields In Photocatalytic Slurry Reactors
(Pergamon-Elsevier Science Ltd., 2003-03)
Photocatalysis in slurry reactors have the particular characteristic that the reacting medium not only absorbs but also scatters photons and both phenomena occurs simultaneously. When this is the case, typical methods used ...
Symmetry in the open-system dynamics of quantum correlations
(2017-12-01)
We study the symmetry properties in the dynamics of quantum correlations for two-qubit systems in one-sided noisy channels, with respect to a switch in the location of noise from one qubit to the other. We consider four ...
Dissipative Quantum Control of a Spin Chain
(American Physical Society, 2015-11-13)
A protocol is discussed for preparing a spin chain in a generic many-body state in the asymptotic limit of tailored nonunitary dynamics. The dynamics require the spectral resolution of the target state, optimized coherent ...
Quantum coherence and uncertainty in the anisotropic XY chain
(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 ...
Excitonic wavefunction engineering based on type II quantum dots
