Physics Colloquium - "Quantum detective stories: Investigating how much time atoms spend in a "forbidden region" and how much time photons spend “inside" atoms."
(sign-up)Aephraim Steinberg, University of Toronto
|Location:||Via ZOOM - see description for information|
|Event Contact:||Suzanne Hallihan
|Sponsor:||UIUC Department Of Physics|
One of the most famous tidbits of received wisdom about quantum mechanics is that “you can’t ask” which path a photon took in an interferometer once it reaches the screen, or in general, that only questions about the specific things you finally measure are well-posed at all. Much work over the past decades has aimed to chip away at this blanket renunciation, and investigate “quantum retrodiction.” Particularly in light of modern experiments in which we can trap and control individual quantum systems for an extended time, and quantum information protocols which rely on “postselection,” these become more and more timely issues.
The ZOOM link will be sent on Wednesday morning to the Physics Faculty, Graduate Student, PDRA, and AP mailing lists. If you are not on one of those lists and are interested in attending, please email Suzanne Hallihan at firstname.lastname@example.org for the link.
