Extended phase-matching conditions for improved entanglement generation
arXiv:quant-ph/0207009 · doi:10.1103/PhysRevA.66.043813
Abstract
Extended phase-matching conditions for spontaneous parametric down-conversion are examined. By augmenting the conventional phase-matching conditions, they permit the creation of a class of frequency-entangled states that generalizes the usual twin-beam biphoton state. An experimental characterization of these states is possible through interferometric coincidence counting.
