Two-photon speckle as a probe of multi-dimensional entanglement.
We calculate the statistical distribution P2(I2) of the speckle pattern produced by a photon pair current I2 transmitted through a random medium, and compare it with the single-photon speckle distribution P1(I1). We show that the purity of a two-photon density matrix can be directly extracted from the first two moments of P1 and P2. A one-to-one relationship is derived between P1 and P2 if the ...
متن کاملExperimental two-photon, three-dimensional entanglement for quantum communication.
Orbital angular momentum entangled photons emitted by a down-conversion source are in higher dimensional entangled states. Here we report the experimental confirmation by demonstrating a violation of a generalized Clauser-Horne-Shimony-Holt-type Bell inequality in three dimensions by more than 18 standard deviations. Higher dimensional entangled states allow the realization of new types of quan...
متن کاملTwo - Photon Physics as a Probe of Uadron Dynamics
Two-photon collisions provide an ideal laboratory for testing lnany features of quantum chromodynamics, espaially the interplay between the vector-meson-dominated and point-like hadronic interactions of the photon. A number of QCD applications are discussed, including: jet and single-particle production at large transverse momentum; the photon structure function and its relationship to the y + ...
متن کاملQuantum entanglement – multi-photon sources
Entanglement lies in the heart of almost all methods of quantum communication and computation. Efficient and economical generation of entangled states of light are of crucial importance for the success of future quantum communication applications. This article introduces the experimental methods to produce entangled light modes both in the discrete and continuous variable regime.
