Implementation of a hybrid scheme for coherent plug-and-play quantum key distribution
(Springer, 2018-07)
We experimentally demonstrate a hybrid configuration for quantum key distribution that combines the simplicity of distributed-phase-reference protocols with the self-referencing features and polarization insensitivity of ...
Semiclassical coherent-states propagator
(American Physical Society, 2013-06)
In this work, we derived a semiclassical approximation for the matrix elements of a quantum propagator in coherent states (CS) basis that avoids complex trajectories; it only involves real ones. For that purpose, we used ...
Quantum coherent tunneling between two atomic-molecular Bose-Einstein condensates
(Springer, 2004-09-01)
We study the quantum coherent tunneling dynamics of two weakly coupled atomic-molecular Bose-Einstein condensates (AMBEC). A weak link is supposed to be provided by a double-well trap. The regions of parameters where the ...

On the concept of entropy for quantum decaying systems
(Springer, 2013-09)
The classical concept of entropy was successfully extended to quantum mechanics by the introduction of the density operator formalism. However, further extensions to quantum decaying states have been hampered by conceptual ...
Entanglement and coherence in a spin-s XXZ system under non-uniform fields
(IOP Publishing, 2017-04)
We investigate entanglement and coherence in an XXZ spin s pair immersed in a non-uniform transverse magnetic field. The ground state and thermal entanglement phase diagrams are analyzed in detail in both the ferromagnetic ...
Controlling phase space caustics in the semiclassical coherent state propagator
(Academic Press Inc Elsevier ScienceSan DiegoEUA, 2008)
Energy transfer in light-harvesting systems: implicatións of structural adaptatións, quantum coherence and correlatións
(2013)
Natural photosynthetic organisms have evolved a highly efficient and robust machinery to convert sunlight into useful chemical energy. Understanding the underlying principies behind such effective process is of fundamental ...
