Decoherence induced by a phase-damping reservoir
R. M. Angelo, E. S. Cardoso, K. Furuya
A phase damping reservoir composed by -bosons coupled to a system of interest through a cross-Kerr interaction is proposed and its effects on quantum superpo sitions are investi…

Entanglement versus mixedness for coupled qubits under a phase damping channel
E. S. Cardoso, M. C. de Oliveira, K. Furuya
Quantification of entanglement against mixing is given for a system of coupled qubits under a phase damping channel. A family of pure initial joint states is defined, ranging from…
