Direct-dynamical entanglement-discord relations
In this article, by considering Bell-diagonal two-qubit initial states under local dynamics generated by the Phase Damping, Bit Flip, Phase Flip, BitPhase Flip, and Depolarizing channels, we report some elegant direct-dynamical relations between geometric measures of Entanglement and Discord. The complex scenario appearing already in this simplified case study indicates that a similarly simple ...

متن کاملDependence of entanglement dynamics on the global classical dynamical regime.
We analyze the connections between the dynamical generation of continuous variable entanglement and the underlying classical trajectories in pairs of coupled oscillators. In the quantization of a periodic cycle, we find periodic entanglement which has twice the frequency of the corresponding classical motion. Such frequency doubling continues to hold true in the entanglement dynamics for a seco...
متن کاملUniversality in Dynamical Formation of Entanglement for Quantum Chaos
At the dawn of the quantum mechanics, entangled states of spatially separated bi-particle systems triggered fierce discussions because of their paradoxical property [1]. These discussions lead to the finding of the inequalities which measure how quantum systems deviate from the classical reality [2]. Recently, a renewed interest has been paid to entanglement since it is recognized as an invalua...
متن کاملGalilean and dynamical invariance of entanglement in particle scattering.
Particle systems admit a variety of tensor product structures (TPSs) depending on the algebra of observables chosen for analysis. Global symmetry transformations and dynamical transformations may be resolved into local unitary operators with respect to certain TPSs and not with respect to others. Symmetry-invariant and dynamical-invariant TPSs are defined and various notions of entanglement are...
