Weakly-entangled states are dense and robust
Roman Orus, Rolf Tarrach
Motivated by the mathematical definition of entanglement we undertake a rigorous analysis of the separability and non-distillability properties in the neighborhood of those three-q…
Neutral Kaons in Medium: Decoherence Effects
A. A. Andrianov, R. Tarrach, J. Taron
We consider departures from hamiltonian dynamics in the evolution of neutral kaons due to their interactions with environment that generate entanglement among them. We propose a ph…
Three-qubit pure-state canonical forms
A. Acin, A. Andrianov, E. Jane +1
In this paper we analyze the canonical forms into which any pure three-qubit state can be cast. The minimal forms, i.e. the ones with the minimal number of product states built fro…
Effective Quark Models in QCD at low and intermediate energies
A. A. Andrianov, V. A. Andrianov, D. Espriu +1
The effective quark models are employed to describe the hadronization of QCD in the quark sector. They reveal a different structure depending on how the spontaneous chiral symmetry…
Triviality of GHZ operators of higher spin
J. Savinien, J. Taron, R. Tarrach
We prove that local observables of the set of GHZ operators for particles of spin higher than 1/2 reduce to direct sums of the spin 1/2 operators , and, therefore, no ne…
Optimal strategies for sending information through a quantum channel
E. Bagan, M. Baig, A. Brey +2
Quantum states can be used to encode the information contained in a direction, i.e., in a unit vector. We present the best encoding procedure when the quantum state is made up of $…
