Abstract

The theory of the two-photon state generated by type-II optical parametric down-conversion is studied with emphasis on the space-time and polarization entanglement of the photons. Several experiments are reviewed that demonstrate various aspects of the quantum nature of this state. The theory of a different type of two-photon interferometer is presented.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Because photons are produced coherently along the entire length of the crystal, one can completely compensate for the longitudinal walk-off.

    “Fortunately, because the photons are produced coherently along the entire length of the crystal, one can completely compensate for the longitudinal walk-off (Rubin et al., 1994).”

    From Multiphoton entanglement and interferometry (2012) · cites this paper as Rubin et al., 1994

  • The purely symmetry origin of HV entanglement explains the difference between the result that HV is maximally entangled and the often encountered opinion that this state is disentangled.

    “This explains the difference between our result that the state HV is maximally entangled and the very often encountered opinion that this state is disentangled [3,28].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
