Influence of a symmetric lossless beam splitter on a non-classical feature of an optical field

Hari Prakash, D. K. Mishra

Recently, it was found [J. Phys. B: At. Mol. & Opt. Phys. 38 , 665 (2005)] that amplitude-squared squeezing, a non-classical feature, can be enhanced during linear mixing with a coherent light beam using a symmetric lossless beam splitter. Here, another example is reported of enhancement of an easily detectable non-classical feature of an optical field in a similar mixing using a symmetric lossless beam splitter.

Quantum switch teleportation with continuous variables using two-mode squeezed light

Yun Zhang, K. Kasai, Masayoshi Watanabe

Summary form only given. The scheme for continuous variable switch teleportation was proposed by using a pair of two-mode squeezed state lights on beamsplitter of 50% and polarizing beam splitter. Teleportation ability is examined by the criteria proposed by Ralph and Lam (1998) from a small signal quantum optical point of view. A pair of two-mode squeezed lights, which are coupled by two modes with identical frequency but orthogonal polarization, are mixed on a 50:50 beamsplitter. The outgoing fields are separated into A,B,C,D, by the polarizing beam splitter based on the polarization. It results in entanglement between the mode A and mode B or mode A and mode D in turn depending the input relative phase between two input two-mode squeezed lights or the quadrature components of squeezing. Thus, switching EPR beams with continuous variable are obtained.
