Quantum Crossing Symmetry as Heart of Ghost Imaging

TL;DR

This paper reveals that ghost imaging can be understood through crossing symmetric photon reactions in nonlinear media, emphasizing energy-momentum conservation over entanglement, and introduces a quantum mirror mechanism.

Contribution

It introduces a novel interpretation of ghost imaging based on crossing symmetric reactions and quantum mirror concepts, challenging the entanglement-based explanation.

Findings

Ghost imaging laws depend solely on energy-momentum conservation.

Crossing symmetric photon reactions are key to understanding ghost imaging.

Quantum mirror provides an intuitive mechanism for ghost imaging.

Abstract

In this paper it is shown that the key to understanding the ghost imaging mystery are the crossing symmetric photon reactions in the nonlinear media. Then, an intuitive mechanism for the description of the ghost imaging in terms of the quantum mirror (QM) is presented. Moreover, we prove that the ghost imaging laws depend only on the energy-momentum conservation and not on the photons entanglement.
