Optical proposals for controlled delayed-choice experiment based on weak cross-Kerr nonlinearities

Optical proposals for controlled delayed-choice experiment based on weak cross-Kerr nonlinearities Employing polarization modes of a photon, we propose two theoretical proposals to exhibit the wave–particle duality of the photon with the assistance of weak cross-Kerr nonlinearities. The first proposal is a classical controlled delayed-choice experiment (that is, Wheeler’s delayed-choice experiment), where we can observe selectively wave property or particle property of the photon relying on the experimenter’s selection, whereas the second proposal is a quantum controlled delayed-choice experiment, by which the mixture phenomenon of a wave and a particle will be exhibited. Both of them can be realized with near-unity probability and embody the charming characteristics of quantum mechanics. The employment of the mature techniques and simple operations (e.g., Homodyne measurement, classical feed forward, and single-photon transformations) provides the feasibility of the delayed-choice experiment proposals presented here. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Quantum Information Processing Springer Journals
