Phys. Rev. A 72, 034101 (2005) [4 pages]Generating optimal states for a homodyne Bell test
Sonja Daffer * and Peter L. Knight Received 14 January 2005; revised 10 June 2005; published 1 September 2005 We present a scheme that produces a conditionally prepared state that can be used for a Bell test based on homodyne detection. The state is near optimal for Bell-inequality violations based on quadrature-phase homodyne measurements that use correlated photon-number states. The scheme utilizes a Gaussian entanglement distillation protocol and uses only beam splitters and photodetection to conditionally prepare a non-Gaussian state from a source of two-mode squeezed states with low squeezing parameter. ©2005 The American Physical Society
