Phys. Rev. A 66, 042319 (2002) [7 pages]Quantum entanglement and squeezing of the quadrature difference of bright light fieldsReceived 3 May 2002; revised 2 July 2002; published 23 October 2002 In this paper we present a scheme in which the amplitude-quadrature difference and phase-quadrature difference of two bright nonclassical beams serve as a pair of observed complementary variables that can be measured directly and can form a new squeezed state. Mixing such two quadrature-difference squeezed-state beams on a beam splitter produces characteristic of the Einstein-Podolsky-Rosen quantum entanglement. The experimental schemes producing such nonclassical beams and its possible applications in quantum information are discussed. © 2002 The American Physical Society URL:
