Abstract
En 中文
Photon correlations represent a central resource in many quantum optics experiments, with applications ranging from quantum information protocols to sensing. Engineering such correlations is often challenging, especially in multi-particle scenarios. This work describes an effective method for shaping spatial correlations between photons by patterning their distinguishability in a quantum interference setup. How one may write and edit these bi-photon correlations between the two output channels of a beam-splitter is presented, where the information encoded remains hidden from conventional intensity measurements. The scheme presented here offers an easy extension to multiparticle scenarios and facilitates the transmission of high-dimensional quantum information, opening new avenues for applications in quantum technologies and imaging protocols.
