QUANTUM TECHOLOGIES THAT REJECT THERMAL NOISE FOR IMPROVEDSNR IN COHERENT-STATE RANGING AND RELATED APPLICATIONS
Abstract
We will carry out a systematic experimental and theoretical study to gain knowledgeand understanding necessary to determine the means by which the signal-to-noise ratio (SNR) ina coherent state (LIDAR) system can be increase by exploiting quantum optical technologies toreject thermal background from the coherent ranging signal. The US PI is Dowling at LSU (theory) and the Israel PI is Eisenberg at Hebrew University of Jerusalem (HUJ) (experiment). LSU and HUJ have an ongoing synergistic collaboration in this field for three years, including visits by the PIs to each other’s universities and the exchange of PhD students, which has led to the preparation of this joint proposal and topics proposed herewith. The LSU has a renowned quantum optics theory program stretching back 40 years, and HUJ is one of the premier universities for quantum optics in Israel. Dowling has over 25-years’ experience in the theory of quantum optics and information, and Eisenberg has a similar track record in the experimental quantum technologies. Our team will develop theory and experimental proofs of principle towards the above stated goal, including: (1.) thermal photon rejection with photostatistics, (2.) thermal photon rejection using first-order quantum coherence, (3.) thermal photon rejection using second-order quantum coherence, (4.) thermal-photon rejection via quantum homodyne.
