Interference of Waves to Interference of Quantum Paths

Speaker: G.S. Agarwal (Texas A& M University)

Time: 14:00-15:00, Friday, March 23, 2018

Venue: Room 201, No. 12 Teaching Building, Yuquan Campus



I will review several land mark effects in quantum optics and how these changed the growth of the field. Although each discovered in a different context, the underlying physics can be understood from a common theme –interference of quantum paths leading to observed signals. I would describe the new physics and a number of applications arising from the interference of independent photons especially in the preparation of entangled states. The interference of quantum paths provides a new understanding of the correlated spontaneous emission and superradiance and more generally the results of measurements on entangled states of a quantum system.
