Journal ArticleDOI
New high-intensity source of polarization-entangled photon pairs.
Paul G. Kwiat,Klaus Mattle,Harald Weinfurter,Anton Zeilinger,Alexander V. Sergienko,Yanhua Shih +5 more
TL;DR: Type-II noncollinear phase matching in parametric down conversion produces true entanglement: No part of the wave function must be discarded, in contrast to previous schemes.
Journal ArticleDOI
Optical imaging by means of two-photon quantum entanglement.
TL;DR: In this article, a two-photon optical imaging experiment was performed based on the quantum nature of the signal and idler photon pairs produced in spontaneous parametric down-conversion, where an aperture placed in front of a fixed detector is illuminated by the signal beam through a convex lens.
Journal ArticleDOI
Observation of two-photon "ghost" interference and diffraction.
TL;DR: Observations of unusual diffraction and interference by two-photon correlation measurements by spontaneous parametric down-conversion are reported.
Journal ArticleDOI
High-speed and high-efficiency travelling wave single-photon detectors embedded in nanophotonic circuits
Wolfram H. P. Pernice,Carsten Schuck,Olga Minaeva,Mo Li,Gregory Goltsman,Alexander V. Sergienko,Hong X. Tang +6 more
TL;DR: This work demonstrates superconducting nanowire detectors atop nanophotonic waveguides, which enable a drastic increase of the absorption length for incoming photons, which allows high on-chip single-photon detection efficiency up to 91% at telecom wavelengths, repeatable across several fabricated chips.
Journal ArticleDOI
Theory of two-photon entanglement in type-II optical parametric down-conversion.
TL;DR: In this article, 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.
