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…
Topological phases and entanglement in real space for 1D SSH topological insulator: effects of first and second neighbor-hoppings
Leonardo A. Navarro-Labastida, Francisco A. Domínguez-Serna, F. Rojas
The hybrid atoms-cell site entanglement in a one-dimensional Su-Schrieffer-Heeger (SSH) topological insulator with first and second neighbor hopping interaction in space representa…
Topological Uhlmann phase transitions for a spin-j particle in a magnetic field
D. Morachis Galindo, F. Rojas, Jesús A. Maytorena
The generalization of the geometric phase to the realm of mixed states is known as Uhlmann phase. Recently, applications of this concept to the field of topological insulators have…
Quantum teleportation with hybrid entangled resources prepared from heralded quantum states
Francisco A Dominguez-Serna, Fernando Rojas, Karina Garay-Palmett
In this work we propose the generation of a hybrid entangled resource (HER) and its further application in a quantum teleportation scheme from an experimentally feasible point of v…
Relationship between the field local quadrature and the quantum discord of a photon-added correlated channel under the influence of scattering and phase fluctuation noise
Francisco A. Dominguez-Serna, Francisco J. Mendieta-Jimenez, Fernando Rojas
We study quantum correlations and discord in a bipartite continuous variable hybrid system formed by linear combinations of coherent states and single photon added cohe…
Entangled photon added coherent states
Francisco A. Dominguez-Serna, Francisco J. Mendieta, Fernando Rojas
We study the degree of entanglement of arbitrary superpositions of photon-added coherent states (PACS) $|ψ\rangle \propto u |α,m\rangle |β,n \rangle+ v |β,n\rangle |α,m\rangl…
