Title: Entanglement versus mixedness for coupled qubits under a phase damping channel
Author: Cardoso, ES
de Oliveira, MC
Furuya, K
Abstract: 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 pure separable states to maximally entangled states. An ordering of entanglement measures is given for a well-defined initial-state amount of entanglement.
