Phys. Rev. A 79, 022121 (2009) [8 pages]Quantum connectivity of space-time and gravitationally induced decorrelation of entanglementReceived 26 August 2008; revised 12 January 2009; published 26 February 2009 We discuss an alternative formulation of the problem of quantum optical fields in a curved space-time using localized operators. We contrast this formulation with the standard approach and find observable differences for entangled states. We propose an experiment in which an entangled pair of optical pulses are propagated through nonuniform gravitational fields and find that the alternative formulation predicts decorrelation of the optical entanglement under experimentally realistic conditions. © 2009 The American Physical Society URL:
