Abstract
Abstract Entanglement and correlation of photons play a central role in quantum information and communication. There are two types of photon correlations: one usually exists in a two‐particle entangled state first conceived by Einstein, Podolsky, and Rosen (EPR) in 1935, while the other occurs in a thermal light source found by Hanbury Brown and Twiss (HBT) in 1956. Many studies are concerned with the physical nature and differences behind the two types of photon correlations. Here, a holography‐inspired linear optical system that generates a pair of conjugate chaotic beams is proposed, which include both HBT‐type and EPR‐like correlations. From principle to experimental generation, the study presents a classical paradigm of a simple bi‐correlation light source for diverse quantum‐mimic applications such as two‐photon imaging.
