DESCRIPTION:Denis Seletskiy\nPlease join us for the QSE Center Quantum 
 Seminar with Prof. Denis Seletskiy from Polytechnique Montreal\, who wil
 l speak\, on Thursday\, December 7\, about “Experimental quantum elect
 rodynamics”.\nLocation: BS 270\n\nPizzas will be available before the 
 seminar at 12:00. All PhDs\, postdocs\, students\, and PIs are welcome to 
 join us.\n\nTITLE: Experimental quantum electrodynamics\n\nABSTRACT:\nTrad
 itional approaches to quantum optics are rooted in the reciprocal\, freque
 ncy-momentum space. In this talk\, I will discuss recent advances toward s
 ub-cycle quantum optics\, where\, instead\, quantum fields are accessed in
  a localized region of space-time [1-2]. Both regimes will be compared sid
 e-by-side to contrast the advantages of each approach\, with a particular 
 emphasis on quantum sensing proposals [3-5] in the mid-infrared frequency 
 range.\nIn the concluding part of the talk\, I will summarize recent advan
 ces in producing few-cycle bright one- and two-mode squeezed vacuum states
  in a single few-cycle temporal mode with macroscopic photon occupation [6
 ]. Such capabilities are poised to unlock a new era of (extreme) nonlinear
  quantum optics in the attosecond regime [7].[1] Direct sampling of electr

 BIO:\nDenis Seletskiy is an Associate Professor of Engineering Physics and
  a holder of Canada Research Chair (Tier 2) in “Ultrafast and Quantum Ph
 otonics” at Polytechnique Montreal. He received his PhD from the Optical
  Sciences and Engineering program at the University of New Mexico in 2010\
 , followed by a National Research Council postdoctoral fellowship at Air F
 orce Research Laboratories (2010-2012) and a 5-year junior group leader po
 sition and Marie Curie Zukuntskolleg Research fellowship at the University
  of Konstanz\, Germany. In 2017 Seletskiy established the femtoQ laborator
 y at Polytechnique\, which is focused on advancing theory\, laser technolo
 gy\, and metrology protocols for time-domain quantum photonics. Since Octo
 ber 2022\, he is leading an EU-CAN consortium in Mid-Infrared Quantum Tech
 nologies for Sensing (MIRAQLS).
