Another dual formulation of the separability problem
D. Salgado, J. L. Sanchez-Gomez, M. Ferrero
We show how the separability problem is dual to that of decomposing any given matrix into a conic combination of rank-one partial isometries, thus offering a duality approach diffe…
On nonlinear evolution and supraluminal communication between finite quantum systems
M. Ferrero, D. Salgado, J. L. Sanchez-Gomez
We revise the 'no-signaling' condition for the supraluminal communication between two spatially separated finite quantum systems of arbitrary dimensions, thus generalizing a simila…
Expressing Decoherence with Spectral and Stochastic Methods
D. Salgado, J. L. Sanchez-Gomez
We suggest a novel proposal to express decoherence in open quantum systems by jointly employing spectral and stochastic methods. This proposal, which basically perturbs the unitary…
Comment on ``Dynamics of open quantum systems initially entangled with environment: Beyond the Kraus representation'' [PRA 64, 062106 (2001)]
D. Salgado, J. L. Sanchez-Gomez
We correct a mistake in a result reported in [PRA 64, 062106 (2001)], where it is rightfully argued that initial correlations between a system and its environment may render the sy…
Lindbladian Evolution with Selfadjoint Lindblad Operators as Averaged Random Unitary Evolution
D. Salgado, J. L. Sanchez-Gomez
It is shown how any Lindbladian evolution with selfadjoint Lindblad operators, either Markovian or nonMarkovian, can be understood as an averaged random unitary evolution. Both mat…
Generalized model-independent approach to intrinsic decoherence
D. Salgado, J. L. Sanchez-Gomez
A formalism is presented to express decoherence both in the markovian and nonmarkovian regimes and both dissipative and nondissipative in isolated systems. The main physical hypoth…
