Production of Entangled Images by Four-Wave Mixing



Alberto M. Marino, Vincent Boyer, Raphael C. Pooser, Paul D. Lett


One of the most important resources in quantum mechanics is entanglement, which is characterized by correlations stronger than the ones allowed classically. As a result, it is at the basis of applications such as quantum cryptography, quantum information, teleportation, etc. The entanglement between two beams of light can be extended to their spatial degrees of freedom, a field known as quantum imaging. The spatial quantum correlations makes it possible to benefit from the intrinsic parallelism of image processing.
