Quantum Imaging Technique Heralds Unjammable Aircraft Detection
From
Arxiv – Quantum Secured Imaging (10 pages)
ABSTRACT – We have built an imaging system that uses a photon’s position or time-of-flight information to image an object, while using the photon’s polarization for security. This ability allows us to obtain an image which is secure against an attack in which the object being imaged intercepts and resends the imaging photons with modified information. Popularly known as “jamming,” this type of attack is commonly directed at active imaging systems such as radar. In order to jam our imaging system, the object must disturb the delicate quantum state of the imaging photons, thus introducing statistical errors that reveal its activity
