Hi,

Here is an advertisement for Jordan Cotler's Colloquium this thursday. Please spread.  Poster included.

=========================================================

Introduction by Frank Wilczek:

This will be the second colloquium sponsored by WINQ, following the one by Jian-Wei Pan last week.  This one will also report new and spectacular experimental results from Pan's group in China.  Using the "color erasure" idea pioneered by Jordan Cotler , which exploits basic quantum principles in an ingenious way, they have resolved two sources separated by 4.2 nm. at a distance of 1.43 km. - well below the diffraction limit.   Jordan will describe the theoretical background to this work as well as the experiment itself.
Title:

>From chromatic interferometry to a new paradigm for experimental physics

Speaker:

Jordan Cotler - Harvard University

Abstract:

In conventional experiments, quantum systems are interrogated by measurement devices which destroy quantum coherence.  We theoretically develop the new subject of 'chromatic interferometry' by going beyond the usual paradigm: we deliberately entangle experimental samples with lab apparatuses and perform coherent quantum operations on the joint system to extract hidden correlations.  This enables a new and powerful method of high-resolution imaging for multi-wavelength sources, which has been experimentally realized by the group of Jian-Wei Pan.  The method has applications ranging from astrophysics to microscopy.More broadly, we will discuss a quantum information-theoretic framework to study experiments where apparatuses can be entangled with experimental samples, and quantum coherence is maintained thereafter.  It can be proved that for several 'model' experiments, there is an exponential savings in resources if the experimentalist can entangle apparatuses with experimental samples.

Subject: [All.non-board.wacqt] WACQT PhD student presentations 3/3.
Message-ID: <013ee4d3-c411-8047-7bcb-8afcdde0863d@teorfys.lu.se>

Dear WACQT PhD students (and other interested attendees),

On Wednesday next week, March 3, we have the second half-day of 
PhD-student presentations. The schedule for the presentations is posted 
on the WACQT graduate school webpage, 
https://www.chalmers.se/en/centres/wacqt/graduate%20school/Pages/PhD-student-presentations.aspx, 
the presentations start 9:00 and end before lunch.

The Zoom meeting room will open 8.45, 15 minutes before the actual 
start, to allow time for equipment check, short information if any and 
some social chat.

Zoomlink to the presentations: https://lu-se.zoom.us/my/peter.samuelsson

If there are any questions, just get back to me.

Best regards,

Peter
