The transverse spatial effects observed in photon pairs produced by parametric down-
conversion provide a robust and fertile testing ground for studies of quantum mechanics …

Publisher Summary With respect to the classical area of imaging, the field of quantum
imaging (QI) aims to devise novel techniques for optical imaging and parallel information …

Breaking the diffraction limit in microscopy by utilizing the quantum properties of light has
been the goal of intense research in recent years. We propose a super-resolution technique …

Two-photon anti-bunching at a beamsplitter is only possible if the photons are entangled in
a specific state, anti-symmetric in the spatial modes. Thus, observation of anti-bunching is an …

The quantum theory of the electromagnetic field uncovered that classical forms of light were
indeed produced by distinct superpositions of nonclassical multiphoton wave packets. This …

We present a study of orbital angular momentum transfer from pump to down-converted
beams in a type-II optical parametric oscillator. Cavity and anisotropy effects are investigated …

We present a technique for measuring the second-order coherence function g (2)(τ) of light
using a Hanbury Brown–Twiss intensity interferometer modified for homodyne detection …

This paper demonstrates the engineering of spatially entangled two-photon states behind a
double slit by tailoring the incident pure two-photon state. We experimentally characterize …

We show theoretically how two-photon fields generated by spontaneous parametric down-
conversion can be used for creating maximally entangled states of multidimensional …

High-order quantum coherence reveals the statistical correlation of quantum particles.
Manipulation of quantum coherence of light in the temporal domain enables the production …
