Abstract

Starting from an arbitrary entangled state of two separated qubits, one can produce a unique state which has the maximal possible entanglement of formation by carrying out local quantum operations and classical communication. We show that this maximal entanglement of formation and the fidelity of the unique state can be expressed as functions of the initial state analytically. We also describe the most efficient procedure of the entanglement manipulation to produce the unique state. (C) 2000 Published by Elsevier Science B.V.
