Dear Professor Rubio
With the *Sofja Kovalevskaja Award*, the Alexander von Humboldt Foundation
is offering promising young researchers from all over the world attractive
career prospects in Germany. *Junior research talents of all disciplines
from abroad* are given the opportunity to establish working groups of their
own at German research institutions.
The Sofja Kovalevskaja Award recognises outstanding talent and creative
research approaches with exceptional conditions: With an*award amount of up
to €1.65 million *each winner receives valuable starting capital to spend
five years pursuing an innovative research project at a research institute
of his or her choice – untroubled by administrative constraints. In
addition, the establishment of their own junior research team enables the
award winners to lay an important foundation for a promising academic
career at a very early stage. Eight awards are expected to be granted.
Outstandingly qualified junior academics of all disciplines from abroad
who completed their doctorate less than six years ago are eligible to apply
for the Sofja Kovalevskaja Award. It is also possible to submit
applications immediately after finishing one’s doctoral studies. *Applications
must be submitted by 31 July 2015*.
We should be very grateful if you would support our search for young
international research personalities by disseminating this announcement at
your institution and also asking your colleagues to draw the attention of
appropriately qualified research talents to this academic award.

Taken Place in Star D463 Oded Regev: Faster algorithms for the

To: theory-seminars(a)csail.mit.edu, seminars(a)csail.mit.edu
Please note the new location for today's seminar will be Star Conf Room D463
Oded Regev: Faster Algorithms for the Shortest Vector Problem
Speaker: Oded Regev, Courant Institute of Mathematical Sciences
Host: Costis Daskalakis, Ankur Moitra, Dana Moshkovitz and Vinod Vaikuntanathan
Date: Thursday, April 23, 2015
Time: 4:15 PM to 5:15 PM
Refreshments Time: 4:00 PM
Location: G449 (Patil/Kiva)
Abstract: We give a randomized ~2^n-time algorithm for solving the
Shortest Vector Problem (SVP)
on n-dimensional lattices, improving on the previous best running time
of 4^n by Micciancio
and Voulgaris (STOC 2010). Despite being the fastest, the algorithm
is arguably also the simplest in this line of work.
The main ingredients used are the discrete Gaussain distribution, an
identity due to Riemann, and a
way to transform samples from a distribution p into samples from the
“square of p†.
Time permitting, we will also discuss an algorithm running in time
2^n{n/2} that solves
another hard lattice problem.
Joint work with Divesh Aggarwal, Daniel Dadush, and Noah Stephens-Davidowitz.

Hi everyone,
Tomorrow Joey will be giving us group meeting. Please see below for the
title and abstract of his talk.
Cheers,
Jennifer
-----------------------------------
What are the signatures of ultrafast energy transfer through a conical
intersection, in a 2D electronic spectrum?
Many incredibly interesting chemical systems exhibit a rapid energy
transfer from an exited electronic state to their ground electronic state, due
to a phenomenon known as a conical intersection. This phenomenon is
actually what allows all creatures on this planet to see and also not
constantly get cancer from the sun; both retinal and all the DNA bases
exhibit this kind of "intersection". It is called so, because it occurs
when two different electronic energy states have [diabatic] nuclear
potential energies which intersect. When this happens, two different
electronic states have the same total potential energy at one (or more than
one) point. Around this intersection point, the Born-Oppenheimer
approximation break down and under certain conditions, a rapid transfer to
the electronic ground state happens. Approximate simulation of this
phenomenon takes up a great deal of scientific effort in the chemical
physics community. Oddly enough, however, no one has yet to use exact
nuclear dynamics to simulate a two-dimensional electronic spectrum in a
system with a conical intersection--which is a shame, because 2D
spectroscopy is how one studies electronic energy transfer. Because of my
established codebase which does exact nuclear dynamics and calculates
spectra, and because of advances in computing power, we are uniquely
positioned to make an interesting, new contribution to this field and look
for fingerprint of conical intersections in 2D spectra for experimentalists
to look for.
*This talk will be a very rough draft for my thesis committee meeting in
mid-May.
**It is my sincere hope that the entirety of my presentation will be
follow-able by every member of the group from new undergrad to Alan.
Please let me know if it is not!

Title: Internal Spin Control and Squeezing in Ensembles of Alkali Atoms
Abstract: Spin squeezed states have applications in metrology and quantum information processing. While there has been significant progress in producing spin squeezed states and understanding their properties, most spin squeezing research to date has focused on ensembles of two-level systems or qubits. We explore squeezed state production in an ensemble of spin f>1/2 alkali atoms (qudits). The Faraday effect, which couples the collective spin of the atomic ensemble and the polarization modes of an optical field, can be used to mediate entangling interactions between the atoms that generate spin squeezing. This process can be enhanced with further control of the atomic qudits. Initial state preparation increases the collective squeezing through enhancement of resolvable quantum fluctuations, but comes at a price of increased decoherence. We find an optimal state preparation, achieving increased squeezing while remaining robust to decoherence. After the collective interaction, qudit control maps the generated entanglement to different pseudo-spin subspaces where it is metrologically useful, e.g., the clock transition or the stretched state for magnetometry. In the latter case, additional internal control can be used to squeeze the individual atoms, further enhancing the total squeezing in a multiplicative manner. These considerations highlight the unique capabilities of our platform: we are able to transfer coherences and correlations between subspaces to explore a wider variety of nonclassical states with ultimate application in sensors or other quantum information processors.

Dear quanta,
Below is an announcement for a talk on classical algorithms but for a
problem where people have been looking for quantum algorithms and using
some techniques that resemble some quantum techniques for lattice problems.
