Phys. Rev. A 68, 012104 (2003) [7 pages]Nonlocality of two-mode squeezing with internal noiseReceived 13 February 2003; published 15 July 2003 We examine the quantum states produced through parametric amplification with internal quantum noise. The internal diffusion arises by coupling both modes of light to a reservoir for the duration of the interaction time. The Wigner function for the diffused two-mode squeezed state is calculated. The nonlocality, separability, and purity of these quantum states of light are discussed. In addition, we conclude by studying the nonlocality of two other continuous-variable states: the Werner state and the phase-diffused state for two light modes. © 2003 The American Physical Society URL:
