Schrödinger cat and Werner state disentanglement simulated by trapped ion systems

2017 · Journal of Physics B Atomic Molecular and Optical Physics

Abstract Disentanglement and loss of quantum correlations due to one global collective noise effect are described for two- qubit Schrödinger cat and Werner states of a four level trapped ion quantum system. Once the Jaynes–Cummings …

Intrinsic correlations for statistical ensembles of Dirac-like structures

2024 · Physical Review A

The Weyl-Wigner formalism for evaluating the intrinsic information of Dirac bispinors as correlated qubits (localized) in a magnetic field is investigated in the extension to statistical ensembles. The confining external field quantizes the quantum correlation …
