Entangling power of symmetric two-qubit quantum gates
D. Morachis, Jesús A. Maytorena
The capacity of a quantum gate to produce entangled states on a bipartite system is quantified in terms of the entangling power. This quantity is defined as the average of the line…

Uhlmann phase in composite systems with entanglement
J. Villavicencio, E. Cota, F. Rojas +2
We study the geometric Uhlmann phase of entangled mixed states in a composite system made of two coupled spin- particles with a magnetic field acting on one of them. Wit…
