Geometric quantifier of the incompatibility of single-particle property attribution in indistinguishable boson systems
P. Céspedes, A. Valdés-Hernández, F. H. Holik +1
Entanglement in indistinguishable particle systems can be characterized by the impossibility of unambiguously attributing a complete set of physical properties to the individual co…
The underlying order induced by orthogonality and the quantum speed limit
Francisco J. Sevilla, Andrea Valdés-Hernández, Alan J. Barrios
We perform a comprehensive analysis of the set of parameters that provide the energy distribution of pure qutrits that evolve towards a distinguishable state at a finit…
Emergent dynamics from entangled mixed states
A. Valdés-Hernández, C. G. Maglione, A. P. Majtey +1
Entanglement is at the core of quantum physics, playing a central role in quantum phenomena involving composite systems. According to the timeless picture of quantum dynamics, enta…
Sudden death of entanglement in fermionic systems under collective decoherence
D. G. Bussandri, A. P. Majtey, A. Valdés-Hernández
We analyze the dynamics of entanglement due to decoherence in a system of two identical fermions with spin interacting with a global bosonic environment. We resort to an appr…
On the spin projection operator and the probabilistic meaning of the bipartite correlation function
Ana María Cetto, Andrea Valdés-Hernández, Luis de la Peña
Spin is a fundamental and distinctive property of the electron, having far-reaching consequences in wide areas of physics. Yet, further to its association with an angular momentum,…
Unified framework to determine Gaussian states in continuous variable systems
Fernando Nicacio, Andrea Valdés-Hernández, Ana P. Majtey +1
Gaussian states are the backbone of quantum information protocols with continuous variable systems, whose power relies fundamentally on the entanglement between the different modes…
Entanglement generation through particle detection in systems of identical fermions
P. A. Bouvrie, A. Valdés-Hernández, A. P. Majtey +2
We investigate the generation of entanglement in systems of identical fermions through a process involving particle detection, focusing on the implications that this kind of proces…
Multipartite concurrence for identical-fermion systems
A. P. Majtey, P. A. Bouvrie, A. Valdés-Hernández +1
We study the problem of detecting multipartite entanglement among indistinguishable fermionic particles. A multipartite concurrence for pure states of identical fermions, each…
Dynamics of entanglement in systems of identical fermions undergoing decoherence
A. Valdés-Hernández, A. P. Majtey, A. R. Plastino
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 imp…
Atomic radiative corrections without QED: role of the zero-point field
Ana María Cetto, Luis de la Peña, Andrea Valdés-Hernández
We derive the atomic radiative corrections predicted by QED using an alternative approach that offers the advantage of physical clarity and transparency. The element that gives ris…
Origin and meaning of quantum nonlocality
L. de la Peña, A. M. Cetto, A. Valdés-Hernández +1
Quantum nonlocality is revisited from a novel point of view by studying the problem of an originally classical particle immersed in the stochastic zero-point radiation field (zpf).…
