Abstract

We propose a Procrustean entanglement concentration scheme for continuous-variable states inspired by the scheme proposed in J. Fiurasek [Phys. Rev. A 67, 022304 (2003)]. We show that the eight-port homodyne measurement of J. Fiurasek [Phys. Rev. A 67, 022304 (2003)] can be replaced by a balanced homodyne measurement with the advantage of providing a success criterion that allows Alice and Bob to determine if entanglement concentration was achieved. In addition, it facilitates a straightforward experimental implementation.
