ECEE Seminar Series: Quantum LIDAR Utilizing Photon-Number Detection, with Lior Cohen

Quantum LIDAR Utilizing Photon-Number Detection

Abstract: Photon-number-resolving detectors (PNRDs), detectors that are sensitive to single photons but can also resolve the number of photons, have been developed in the last few decades. Nowadays, high performance PNRDs are available commercially, enabling implementations of quantum applications.

In this talk, I will show how photon-number detection can be exploited to demonstrate quantum enhancement for rangefinders and LIDARs. I will present experimental results of a PNRD-based rangefinder and LIDAR. Then, the improvement over classical devices and the way to optimize it will be discussed.

Bio: Lior Cohen is a research associate of Electrical, Computer and Energy Engineering at the University of Colorado Boulder. He received the B.Sc., M. Sc. and Ph.D. degrees from the Hebrew University of Jerusalem. After completing his Ph.D., Lior joined Prof. Jonathan Dowling’s group at Louisiana State University, where he was eventually promoted to a research professor. His research interests include quantum optics, quantum sensing, quantum simulation and quantum information.
