Codificação de duas imagens na função de onda de um fóton

Abstract

In this work we propose a quantum optics experiment to encode the information about two two-dimensional objects into the wavefunction of a photon. The method we propose uses parametric downconversion of laser light in order to generate pairs of entangled photons. One of the objects is to be placed along the pump beam, its angular spectrum being transferred to the down-converted photons. The second object is placed along the path taken by one of the photons. Upon detection of that photon, and depending on the experimentalist’s choice of lens, the intensity profile on the detection plane of the other photon will match that of one object or the other.
