Maximizing the entanglement of two mixed qubits

arXiv:quant-ph/0103113 · doi:10.1103/PhysRevA.64.030302

Abstract

Two-qubit states occupy a large and relatively unexplored Hilbert space. Such states can be succinctly characterized by their degree of entanglement and purity. In this letter we investigate entangled mixed states and present a class of states that have the maximum amount of entanglement for a given linear entropy.
