Contribution

It introduces a novel protocol that detects jamming and recovers images, especially effective in quantum ghost imaging with entangled light.

Findings

Increased jamming detection probability with entangled light.

Effective image recovery in noisy environments.

Applicable to quantum and classical imaging systems.

Abstract

We describe a protocol by which an imaging system could be protected against jamming by a malevolent party. Our protocol not only allows recognition of the jamming, but also allows for the recovery of the true image from the jammed one. We apply the method to jamming of quantum ghost imaging, for which the jamming detection probability is increased when the imaging light is entangled. The method can also be used to provide image recovery in general noisy environments.
