Abstract
A quantum illumination apparatus includes an ion trap in a cryogenic cooler. The ion trap uses electric and magnetic fields to trap an ion and the quantum illumination apparatus uses the trapped ion to produce a signal photon for use in quantum illumination. The signal photon has correlations with an idler field stored with use of the trapped ion, as a phonon of the trapped ion. A signal photon transmission line extends between the ion trap and an antenna. The signal photon may be scattered, e.g., reflected or refracted, by a target object back to the antenna, and the transmission line transmits the signal photon back to the ion trap. The ion trap generates an electrical signal based on correlations between the signal photon and the idler field. The quantum illumination apparatus is arranged to detect reception of the signal photon based on this generated electrical signal.
