Spatial two-photon coherence of the entangled field produced by down-conversion using a partially spatially coherent pump beam
We study the spatial coherence properties of the entangled two-photon field produced by parametric downconversion (PDC) when the pump field is, spatially, a partially coherent beam. By explicitly treating the case of a pump beam of the Gaussian Schell-model type, we show that in PDC the spatial coherence properties of the pump field get entirely transferred to the spatial coherence properties o...
متن کاملGeneration and Manipulation of Spatially Entangled Photon Pairs in Nonlinear Waveguides
Spatial encoding of photonic quantum information offers the advantage of high dimensionality, which can increase the throughput and security of quantum communication protocols. Truly secure quantum communication protocols rely on entanglement. Here we show multimode nonlinear waveguides as a viable platform for integrated generation and manipulation of transverse-mode photonic entanglement. We ...
متن کاملGeneration of Entangled Two-Photon Binomial States in Two Spatially Separate Cavities
We propose a conditional scheme to generate entangled two-photon generalized binomial states inside two separate single-mode high-Q cavities. This scheme requires that the two cavities are initially prepared in entangled one-photon generalized binomial states and exploits the passage of two appropriately prepared two-level atoms one in each cavity. The measurement of the ground state of both at...
متن کاملSemiconductor devices for entangled photon pair generation: a review.
Entanglement is one of the most fascinating properties of quantum mechanical systems; when two particles are entangled the measurement of the properties of one of the two allows the properties of the other to be instantaneously known, whatever the distance separating them. In parallel with fundamental research on the foundations of quantum mechanics performed on complex experimental set-ups, we...
متن کاملSpatially Coherent Random Forests
Spatially Coherent Random Forest (SCRF) extends Random Forest to create spatially coherent labeling. Each split function in SCRF is evaluated based on a traditional information gain measure that is regularized by a spatial coherency term. This way, SCRF is encouraged to choose split functions that cluster pixels both in appearance space and in image space. In particular, we use SCRF to detect c...
