Hey Everyone,
Please email me your orders today by 2PM. I will not be in the office to collect them by hand, but will still resolve them and have it up on the wiki by the time group meeting is done.
Kind Regards,
Jon
Hi Quanta
We will meet on Friday at 11:00 in 6-310. We will have 3 visitors, Sergio Boixo, Federico Spedalieri and Bob Lucas who will tell us about what they have been doing.
Best,
Eddie

Hi Everyone,
This Friday, Thomas Markovich will be presenting group meeting. For
this Friday only, group meeting will be at 2pm in the Division Room
(note that this is an hour earlier than normal). Thomas's abstract is
included below.
Title: 1) Spectral Densities from Super Resolution and 2) Thermal
Electronic Structure
This will be a two part group meeting.
In the first part, I'll introduce Super-Resolution for the recovery of
atomistic spectral densities in an efficient fashion. The idea is to
apply a novel signal processing technique, known as super resolution,
combined with a ``dictionary'' of physically-motivated bath modes, to
derive spectral densities from AIMD simulations - the computational
bottleneck. Our approach reduces the required simulation time and
provides a more accurate spectral density than can be obtained via
standard Fourier transform methods. Moreover, the spectral density is
provided as a convenient closed-form expression, which can be
integrated analytically and thus directly inputted into master
equation simulations. Dynamical simulations using the hierarchical
equations of motion and second order time-convolutionless master
equation with our newly-developed spectral densities confirm the
usefulness of the technique to more accurately model the dynamics of
the light-harvesting Fenna-Matthews-Olsen (FMO) complex.
In the second part, I'll introduce Thermal Full Configuration
Interaction Quantum Monte Carlo (FCIQMC). Electronic structure remains
a significant problem in computational chemistry because you usually
trade accuracy for computational feasibility. In recent years, Alavi
et al have introduced a technique to treat many electron systems using
monte-carlo that permits milihartree level accuracy for systems of 100
or more electrons. FCIQMC does this by performing monte-carlo in the
space of determinants instead of real space. Our goal is to apply this
technique to systems at finite temperature to investigate the
chemistry of large thermalized systems.

Hi everyone,
I left a bag of Jolly ranchers, probably dated from 2008, in the big
office. For those brave of stomach, there is no expiry date ;). I
believe this is heritage left to us by Jacob Biamonte ..

Workshop on New Mathematical Directions for Quantum Information
2-6 September 2013
Isaac Newton Institute for Mathematical Sciences
Cambridge, UK
(in association with the Newton Institute programme Mathematical
Challenges in Quantum Information, 27 August - 20 December 2013)
DEADLINE FOR APPLICATIONS: 7 June 2013
In recent years the field of quantum information theory has undergone
explosive growth, and progress has been made on many of the most
long-standing open problems in the field. Such progress has frequently
relied on increasingly sophisticated and diverse mathematical tools.
The goal of this workshop is to widely disseminate knowledge of these
tools and the underlying mathematics involved, and to discuss exciting
new directions for the field.
The workshop, which is the kick-off event for the programme
Mathematical Challenges in Quantum Information, will bring together
researchers from within and outside quantum information theory, with
expertise in a variety of areas. The (very far from exhaustive) list
of topics which will be covered includes:
- De Finetti theorems
- Information-theoretic techniques in quantum physics
- Interactive proofs
- Measure concentration
- Quantum computational complexity
- Random matrix theory
- XOR games
The workshop will take place between Monday 2nd September and Friday
6th September 2013. It will consist of a series of tutorial and
invited talks, encompassing both presentations of recent results in
quantum information theory and introductions to the mathematical tools
which can be used to attack outstanding problems in the field. There
will also be a poster session, at which attendees are encouraged to
present their work.
Invited speakers include:
Andris Ambainis - Fernando Brandao - Matthias Christandl - Benoit
Collins - Toby Cubitt - Nilanjana Datta - David Gross - Aram Harrow -
Jonathan Keating - Debbie Leung - Ion Nechita - David Perez Garcia -
Miklos Santha - Stanislaw Szarek - Thomas Vidick - Michael Wolf.
For further details, and to apply to attend, please see the workshop
web page at http://www.newton.ac.uk/programmes/MQI/mqiw01.shtml . The
deadline for applications is 7 June 2013.
Organisers: Ashley Montanaro (Cambridge/Bristol), Noah Linden
(Bristol) and Andreas Winter (Bristol/Barcelona).

While the controversy will likely spin on for a while, here's a paper
that was just posted to the arxiv on a classical model that gives the
same distribution as the DWave paper out of IBM Research. It seemed
particularly topical given our visitors this week... Enjoy

Are you interested in Big Data? Want to know about careers in business
Analytics? Come hear from GSAS alum, Tom Davenport, who literally wrote the
book on business analytics, the hottest growing field for PhD students in
North America. If you use Netflix, then you may know it consistently
predicts which movies you will prefer better than you can – this is the
essence of analytics. In today’s competitive global economy, organizations
are looking for PhDs with personality who can demystify big data trends
into understandable business terms. Professor Davenport holds the
President's Chair in the Information Technology Management Division of
Babson College and co-directs the Working Knowledge Research Center there
and is currently a visiting professor at Harvard Business School. ****
