Fan: Quantum receivers beyond the stand quantum limit of coherent optical communicationsExport this event to calendar

Tuesday, April 8, 2014 — 11:00 AM EDT

Jingyun Fan, National Institute of Standards and Technology

Measurements based on the quantum properties of physical system have enabled many tasks which are not possible by any classical means. In this talk, I introduce two quantum receivers that discriminate nonorthogonal optical coherent states unconditionally surpassing the standard quantum limit, with mean photon numbers ranging from single photon level to many photons, thus bridging the gap between quantum information technology and state-of-the art coherent communications. In particular, we expect significant reduction in latency when applying the receiver to current optical communications.

BIO: Jingyun Fan received his PhD degree in Physics from University of Maryland at College Park in 2002. He then spent a year and half in NEC Research Institute in Princeton, New Jersey. Since 2004, he has been with the National Institute of Standards and Technology and the Joint Quantum Institute of University of Maryland. He contributed to the early development of fiber-based photonic entanglement, which is now a standard tool as an alternative to spontaneous parametric down-conversion for quantum information processing tasks. His contributions to spontaneous parametric down-conversion include achieving the collection efficiency for a two-photon pair source exceeding the threshold needed for a loop-hole free test of Bell’s inequality. His recent work in the field of quantum measurement science involves the demonstration of a number of strategically designed quantum measurement protocols that bridge the gap between quantum communication and coherent optical communication for the first time. His most recent work explores the interaction of light in complex photonic systems as a way to simulate a range of physical phenomena not easily accessible through other means.
