Enhancement of quantum speed limit time due to cooperative effects in multilevel systems
(IOP Publishing, 2015-08)
Deriving minimum evolution times is of paramount importance in quantum mechanics. Bounds on the speed of evolution are given by the so called quantum speed limit (QSL). In this work we use quantum optimal control methods ...
The classical limit of non-integrable quantum systems, a route to quantum chaos
(Elsevier, 2006-04)
The classical limit of non-integrable quantum systems is studied. We define non-integrable quantum systems as those, which have, as their classical limit, a non-integrable classical system. This quantum systems will be the ...
Comment on "modified quantum-speed-limit bounds for open quantum dynamics in quantum channels"
(American Physical Society, 2018-04)
In a recent paper [Phys. Rev. A 95, 052118 (2017)2469-992610.1103/PhysRevA.95.052118], the authors claim that our criticism, in Phys. Rev. A 94, 052125 (2016)2469-992610.1103/PhysRevA.94.052125, to some quantum speed limit ...
Quantum control landscape for a two-level system near the quantum speed limit
(IOP Publishing, 2018-08)
The core problem in optimal control theory applied to quantum systems is to determine the temporal shape of an applied field in order to maximize the expected value of some physical observable. The complexity of this ...
Quantum decoration transformation for spin models

Decoherence and intertheory relations in quantum realismDecoherencia y relaciones interteóricas en el realismo cuántico
(Universidad Nacional de QuilmesUniversidad Nacional de Tres de Febrero, 2019-04-01)
The complex relation between quantum mechanics and classical mechanics is crucial in the philosophy of modern physics, and it cuts across current quantum physics. This paper is divided in two parts. In the first part I ...
Fundamental limits for cooling of linear quantum refrigerators
(American Physical Society, 2017-01)
We study the asymptotic dynamics of arbitrary linear quantum open systems that are periodically driven while coupled with generic bosonic reservoirs. We obtain exact results for the heat flowing from each reservoir, and ...
