Rev. lett., quant-ph/0109135 Abstract It is shown that parametric downconversion, with a short-duration pump pulse and a long nonlinear crystal, can produce a frequency-entangled biphoton state whose individual photons are coincident in frequency. Quantum interference experiments which distinguish this state from the familiar time-coincident biphoton are described.         Home | About the Program | Our Research | Publications | People Related MURIs | Contact © Massachusetts Institute of Technology
