A simple proof of the Jamiolkowski criterion for complete positivity of linear maps
D. Salgado, J. L. Sanchez-Gomez, M. Ferrero
We give a simple direct proof of the Jamiolkowski criterion to check whether a linear map between matrix algebras is completely positive or not. This proof is more accesible for ph…
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…
Quantum Mechanics, is it magic?
M. Ferrero, D. Salgado, J. L. Sanchez-Gomez
We show that quantum mechanics is the first theory in human history that violates the basic a priori principles that have shaped human thought since immemorial times. Therefore alt…
A formula for the Bloch vector of some Lindblad quantum systems
D. Salgado, J. L. Sanchez-Gomez
Using the Bloch representation of an N-dimensional quantum system and immediate results from quantum stochastic calculus, we establish a closed formula for the Bloch vector, hence…
Generalized Einstein gravities and generalized AdS symmetries
L. Cardenas, J. Diaz, P. Salgado +1
We consider the curvatures 2 form asociated with AdSL4 valued one-form gauge connetion, and then we construct a four-dimensional action that generalize the Einstein-Hilbert gravity…
A Critical Discussion About The Methodology Of Quantum Theory
M. Ferrero, D. Salgado, J. L. Sanchez-Gomez
It is argued that the traditional "realist" methodology of physics, according to which human concepts, laws and theories can grasp the essence of reality, is incompatible with the…
