SUMMARY:Séminaire/Seminar - Dan Oron - Nonclassical photon statistics as a
  resource in microscopy - 21/09/26
DESCRIPTION:[wp-svg-icons icon="location" wrap="I"] 22-23 317\n\nDan Oron\,
  the Harry Weinrebe professor of laser physics at Weizmann Institute of 
 Science\n\nAbstract\n\nFar-field optical microscopy beyond the Abbe diffra
 ction limit is already a reality. Yet\, while Abbe's theory was based on c
 lassical physics\, quantum mechanical phenomena were only very recently us
 ed for improving the performance of microscopes. Most realizations of “q
 uantum microscopes” follow a similar logic. First\, a quantum state of l
 ight is generated. Then it interacts with the sample and the sample induce
 d changes are detected\, mostly via some form of quantum state tomography.
  I will present an alternative approach\, where the quantum resource is ba
 sed on harnessing light emission from single quantum entities\, and show h
 ow we increase the resolution of optical microscopes by harnessing the qua
 ntum phenomenon of fluorescence antibunching.  This can be viewed as a qu
 antum extension of the approach pioneered by Hanbury Brown and Twiss\, usi
 ng (classical) photon correlations and photon statistics in augmenting ast
 ronomical measurements already in the 1950s. Importantly\, technological a
 dvances in detector technology have made parallelized characterization of 
 photon statistics beyond the time domain feasible and now offer multiple o
 pportunities in imaging and spectroscopy. Similarly\, advances in data pro
 cessing now allow for efficient extraction of weak quantum signatures from
  noisy signals. Finally\, I will discuss the current status and potential 
 future applications of large format single photon detector arrays for such
  applications.
