Phys. Rev. A 64, 042310 (2001) [4 pages]Quantum correlations in two-boson wave functionsReceived 12 April 2001; published 13 September 2001 We present the Schmidt decomposition for arbitrary wave functions of two indistinguishable bosons, extending the recent studies of entanglement or quantum correlations for two fermion systems [J. Schliemann et al., Phys. Rev. B 63, 085311 (2001) and quant-ph/0012094]. We point out that the von Neumann entropy of the reduced single-particle density matrix remains to be a good entanglement measure for two identical particles. © 2001 The American Physical Society URL:
