Spin-1/2 geometric phase driven by decohering quantum fields
A. Carollo, I. Fuentes-Guridi, M. Franca Santos +1
We calculate the geometric phase of a spin-1/2 system driven by a one and two mode quantum field subject to decoherence. Using the quantum jump approach, we show that the correctio…

Optimal conclusive teleportation of quantum states
L. Roa, A. Delgado, I. Fuentes-Guridi
Quantum teleportation of qudits is revisited. In particular, we analyze the case where the quantum channel corresponds to a non-maximally entangled state and show that the success…

Geometric phase in open systems
A. Carollo, I. Fuentes-Guridi, M. Franca Santos +1
We calculate the geometric phase associated to the evolution of a system subjected to decoherence through a quantum-jump approach. The method is general and can be applied to many…
