[Aspuru-Guzik Group List] [qip] Fwd: Postdoc position is available

by Aram Harrow

If you speak both English and Chinese and want to postdoc with Hayashi, then this is a good opportunity. Also - we won't have a group meeting tomorrow since many of us are away in California. ---------- Forwarded message ---------- From: Masahito Hayashi <masahito(a)math.nagoya-u.ac.jp> Date: Thu, May 31, 2018 at 3:14 AM Subject: Postdoc position is available To: aram(a)mit.edu Dear Aram Recently, as a visiting professor, I joined Institute for Quantum Science and Engineering, Southern University of Science and Technology (SUSTech) in China. The detail information is available from the following. http://siqse.sustc.edu.cn/ Since this is a visiting position, I still keep my original position in Nagoya University. Fortunately, I can employ postdoc(s) with annual salary pre-tax 300,000 RMB. I am seeking a good candidate satisfying the following conditions. * The candidate is interested in theory of quantum information. * The candidate has a potential to work with me. * The candidate can speak English and Chinese. I think that SUSTech is one of best places to study quantum information in China. In future, I can employ postdoc(s) who can speak only English. But, in the current stage, I need a postdoc to speak both of English and Chinese. If you know a good Chinese researcher in quantum information, I would like you to recommend him/her to consider this position. Best, Masahito -- Masahito Hayashi <masahito(a)math.nagoya-u.ac.jp> _______________________________________________ qip mailing list qip(a)mit.edu http://mailman.mit.edu/mailman/listinfo/qip

Correction: The talk is at 12:00 pm. There is no 10-minute speaker.

(617) 496-2544 From: "Dakoulas, Samantha R" <sdakoulas(a)fas.harvard.edu> Date: Thursday, May 31, 2018 at 10:48 AM Subject: ITAMP Special Seminar - Tuesday, June 5 @ 4:00 - Prof. Jan Rost ITAMP Special Seminar Tuesday, June 5, 2018 4:00 PM, CfA, 60 Garden St., B-105 Prof. Jan Rost, Max Planck Institute for the Physics of Complex Systems “Electron dynamics induced by light pulse derivatives” Attosecond physics with frequencies in the XUV range can achieve pulse durations which are comparable with the time scale of the bound orbital the light pulse couples to. This will give rise to non-adiabatic ionization in which the electron is sensitive to light pulse derivatives. Hence, a simple Gaussian pulse acts like a double pulse and leads to a natural pump probe scenario as well a Stueckelberg oscillations. How large the non-adiabatic effects are depends on the AC Stark shift of the bound orbital. We will illustrate these effects with a simple model of a negative ion. The phenomena discussed link the intrinsic time-scale of the particle coupled to an external oscillating field to its frequency and envelope where the envelope can vary at any time scale provided that the particle’s time scale is comparable or slower. To demonstrate how general these links are we conclude by re-interpreting Fermi’s golden rule in the light of the non-adiabatic ionization perspective. Student Presentation will begin at 4:00 Guest Presentation will begin at 4:30 PM Refreshments will be provided.

by Ian Kivlichan

Hi all, Tomorrow Mahmoud will speak at group meeting. His title and abstract are below! All the best, Ian ----------------- Quantum simulation of open systems dynamics using a hybrid quantum-classical algorithm There has recently been a great deal of interest in quantum simulating of dynamics of systems interacts with their surrounding environment. Here, we demonstrate a hybrid quantum-classical optimization method using variational approach to the Liouville-von Neumann equation. Then, we consider quantum dynamics simulation of open systems in case of system-environment classical correlation in disordered quantum systems.

[Aspuru-Guzik Group List] [Theochem] Professor John Stanton seminar.

by Teresa Tamayo

Dear all, Professor Stanton from the University of Florida ( https://sites.google.com/site/stantonresearchgroup/), will give a seminar today at MIT, 4:15 pm, you can find the abstract below. Best, Tere ------- When: 4:15 Wednesday, May 23rd. Where: MIT building four room 4-163 My Longterm Relationship with a Difficult Molecule John F. Stanton This talk reviews the spectroscopy of the NO3 radical, which is both fascinating for theoreticians as well as an important player in the environment. In particular, the quest to fully understand the spectroscopy of NO3 – which has not yet been achieved – has been a “hobby” of mine for essentially the entirety of my scientific career. I will attempt to present a brief history of the science done on this molecule since 1881 as a contextual frame for my own theoretical efforts to understand its spectra and electronic states. The journey starts during my graduate school days, when I was naive and knew nothing. It continues through current times. While I still don’t know very much, I have learned a lot along the way that I will share with you.

[Aspuru-Guzik Group List] [qip] Felix Leditzky visit and talk

by Aram Harrow

Dear quanta, This week (i.e. starting now) Felix Leditzky from UC Boulder is visiting us. He will be in 6-402. I've cc'ed him so feel free to get in touch if you want to meet him. Here is his webpage: http://jila.colorado.edu/~fele9729/academic.html He is speaking on Friday at 1:30pm, details below. Title: Asymptotic performance of port-based teleportation Abstract: Port-based teleportation (PBT) is a variant of the well-known task of quantum teleportation in which Alice and Bob share multiple entangled states called "ports". While in the standard teleportation protocol using a single entangled state the receiver Bob has to apply a non-trivial correction unitary, in PBT he merely has to pick up the right quantum system at a port specified by the classical message he received from Alice. PBT has applications in instantaneous non-local computation and can be used to attack position-based quantum cryptography. Since perfect PBT protocols are impossible, there is a trade-off between error and entanglement consumption (or the number of ports), which can be analyzed using representation theory of the symmetric and unitary groups. In particular, without loss of generality the resource state can be assumed to have a “purified" Schur-Weyl duality symmetry. I will give an introduction to the task of PBT and its symmetries, and show how the asymptotics of existing formulas for the optimal performance for a large number of ports can be derived using a connection between representation theory and the Gaussian unitary ensemble. Joint work with M. Christandl, C. Majenz, G. Smith, F. Speelman & M. Walter. _______________________________________________ qip mailing list qip(a)mit.edu http://mailman.mit.edu/mailman/listinfo/qip
