ABSTRACTS Title: Nonclassical Fields and the Nonlinear Interferometer Authors: Barry C. Sanders, Dien A. Rice Comments: 21 pages, 2 figures http://xxx.lanl.gov/abs/quant-ph/9812010 Abstract: We demonstrate several new results for the nonlinear interferometer, which emerge from a formalism which describes in an elegant way the output field of the nonlinear interferometer as two-mode entangled coherent states. We clarify the relationship between squeezing and entangled coherent states, since a weak nonlinear evolution produces a squeezed output, while a strong nonlinear evolution produces a two-mode, two-state entangled coherent state. In between these two extremes exist superpositions of two-mode coherent states manifesting varying degrees of entanglement for arbitrary values of the nonlinearity. The cardinality of the basis set of the entangled coherent states is finite when the ratio $\chi / \pi$ is rational, where $\chi$ is the nonlinear strength. We also show that entangled coherent states can be produced from product coherent states via a nonlinear medium without the need for the interferometric configuration. This provides an important experimental simplification in the process of creating entangled coherent states. _________________________________________________________________________ Title: Characterizing Greenberger-Horne-Zeilinger Correlations in Nondegenerate Parametric Oscillation via Phase Measurements Authors: W. J. Munro and G. J. Milburn Comments: published PRL -- November 16, 1998 -- Volume 81, pp. 4285-4288 Abstract: We present a potential realization of the Greenberger-Horne-Zeilinger ``all or nothing'' contradiction of quantum mechanics with local realism using phase measurement techniques in a simple photon number triplet. Such a triplet could be generated using nondegenerate parametric oscillation. ******************************************************************************* 2.
