Controlling open quantum systems using fast transitions
(American Physical Society, 2013-02-13)
Unitary control and decoherence appear to be irreconcilable in quantum mechanics. When a quantum system interacts with an environment, control strategies usually fail due to decoherence. In this article we implement a ...
Dynamics of entanglement in systems of identical fermions undergoing decoherence
(American Physical Society, 2015-03)
Information that is stored in quantum-mechanical systems can be easily lost because of the interaction with the environment in a process known as decoherence. Possible physical implementations of many processes in quantum ...
Irreversibility in quantum maps with decoherence
(The Royal Society, 2011-01)
The Boltzmann echo (BE) is a measure of irreversibility and sensitivity to perturbations for non-isolated systems. Recently, different regimes of this quantity were described for chaotic systems. There is a perturbative ...
THE DECOHERENCE-FREE SUBALGEBRA OF A QUANTUM MARKOV SEMIGROUP WITH UNBOUNDED GENERATOR
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2010)
Let T be a quantum Markov semigroup on B(h) with a faithful normal invariant state.. The decoherence-free subalgebra N(T) of T is the biggest subalgebra of B(h) where the completely positive maps T(t) act as homomorphisms. ...
Thermal corrections to quantum friction and decoherence: A closed-time-path approach to atom-surface interaction
(American Physical Society, 2019-05-15)
In this paper we study the dissipative effects and decoherence induced on a particle moving at constant speed in front of a dielectric plate in quantum vacuum, developing a closed-time-path (CTP) integral formulation in ...
Decoherence scaling transition in the dynamics of quantum information scrambling
(American Physical Society, 2021-07)
Reliable processing of quantum information for developing quantum technologies requires precise control of out-of-equilibrium many-body systems. This is a highly challenging task because the fragility of quantum states to ...
Isomerism and decoherence
(Springer, 2016-03)
In the present paper we address the problem of optical isomerism embodied in the socalled "Hund´s paradox", which points to the difficulty to account for chirality by means of quantum mechanics. In particular, we explain ...
Chaos, decoherence and quantum cosmology
(IOP Publishing, 2012-06)
In this topical review we discuss the connections between chaos, decoherence and quantum cosmology. We understand chaos as classical chaos in systems with a finite number of degrees of freedom, decoherence as environment ...
Interpretation and Decoherence: A Contribution to the Debate Vassallo & Esfeld Versus Crull
(Springer, 2017-10)
Letter to the Editor
Decoherence of quantum Markov semigroups
(INST MATHEMATICAL STATISTICS, 2005)
Quantum Decoherence consists in the appearance of classical dynamics in the evolution of a quantum system. This paper focuses on the probabilistic interpretation of this phenomenon, connected with the analysis of classical ...
