Measurement of one-photon and two-photon wavepackets in spontaneous parametric down-conversion
Yoon-ho Kim
One-photon and two-photon wavepackets of entangled two-photon states in spontaneous parametric down-conversion (SPDC) fields are calculated and measured experimentally. For type-II…
Observation of correlated-photon statistics using a single detector
Yoon-Ho Kim, Warren P. Grice
We report experimental observations of correlated-photon statistics in the single-photon detection rate. The usual quantum interference in a two-photon polarization interferometer…
Quantum interference with beamlike type-II spontaneous parametric down-conversion
Yoon-Ho Kim
We implement experimentally a method to generate photon-numberpath and polarization entangled photon pairs using ``beamlike'' type-II spontaneous parametric down-conversion (SPD…
Reliability of the beamsplitter based Bell-state measurement
Yoon-Ho Kim, Warren P. Grice
A linear 50/50 beamsplitter, together with a coincidence measurement, has been widely used in quantum optical experiments, such as teleportation, dense coding, etc., for interferom…
Two-photon interference without bunching two photons
Yoon-Ho Kim
We report an interference experiment in which the two-photon entangled state interference cannot be pictured in terms of the overlap and bunching of two individual photons on a bea…
Quantum interference with distinguishable photons through indistinguishable pathways
Yoon-Ho Kim, Warren P. Grice
We report a two-photon interference experiment in which the detected photons have very different properties. The interference is observed even when no effort is made to mask the di…
