Quantum Sensors

Abstract

(U) The Quantum Sensors program exploits non-classical effects to improve the resolution and range of military sensors. The objective of the program is to enhance sensitivity, resolution, and effectiveness of electromagnetic sensors beyond what is classically possible. In the initial effort, the types of sensors that propagate entangled light out to and back from a target were proven to be ineffective when realistic scattering and absorption occur between the source and the target. Sensors that propagate classical light to the target but use non-classical effects only in the receiver were shown to provide qualitative advantages over their classical counterparts. These include compensation for soft aperture losses using squeezed vacuum injection and compensation for detectors’ quantum inefficiency using noiseless amplification. A new approach, quantum illumination, retains some entangled light in the receiver and transmits the remainder to the target promising substantial enhancements over detection and imaging of targets in the presence of high levels of noise and loss.
