Title: Quantum matching problems
Speaker: Youming Qiao, UTS
Time/Location: 2-3pm, 16 March 2016 (Wed) / CB10.02.410, UTS
The first problem is the well-known polynomial identity testing problem, for which a deterministic efficient solution implies a strong arithmetic circuit lower bound. The second problem has a rich history and has appeared in various forms in a remarkable number of mathematical and computational areas. For example, it is a key problem in the theory of arithmetic circuits with divisions, as recently studied by Hrubeš and Wigderson. After introducing these problems, we will present a couple of ingredients in a recent deterministic efficient algorithm for the second problem. These include a polynomial degree upper bound on generating the ring of matrix semi-invariants, and a linear algebraic analogue of the augmenting path technique.

CALL FOR PAPERS
The 11th Conference on the Theory of Quantum Computation, Communication, and Cryptography – TQC 2016
Freie Universität Berlin
Berlin, Germany
27-29 September 2016
http://tqc2016.physik.fu-berlin.de/
This is the eleventh in a series of conferences that aims to bring together the leading researchers in the areas of quantum computation, quantum communication and quantum cryptography. TQC covers all theoretical aspects of quantum information and submissions on these topics are solicited.
Areas of interest include, but are not restricted to:
* quantum algorithms
* models of quantum computation
* quantum complexity theory
* simulation of quantum systems
* quantum cryptography
* quantum communication
* quantum estimation and measurement
* intersection of quantum information and condensed-matter theory
* quantum coding theory
* fault-tolerant quantum computing
* entanglement theory
Important dates:
* Paper/Talk/Early-Poster submission deadline: May 16, 2016
* Decision notification: July 5, 2016
* Final manuscript deadline: July 23, 2016
* Late-Poster submission deadline: August 17, 2016
* Conference: 27-29 September, 2016
Two tracks: Conference(talk + proceedings) and Workshop(talk only). As the goal of TQC is to bring together researchers on all aspects of quantum information, submissions are solicited for two tracks:
* Conference (talk + proceedings): Submissions to this track must be original papers that have not previously appeared in published form. Accepted papers will be presented orally at the conference and will appear in the conference proceedings. The proceedings will be published by the OpenAccess LIPIcs (Leibniz International Proceedings in Informatics).
* Workshop(talk only): We solicit submissions for talk-only papers; accepted submissions will be presented orally at the conference but will not appear in the proceedings. This track allows authors to publish their work elsewhere and accepts already published material.
Programme committee:
* Gorjan Alagic
* Gilles Brassard
* Anne Broadbent (chair)
* André Chailloux
* Giulio Chiribella
* Frédéric Dupuis
* Joseph Fitzsimons
* Steve Flammia
* Sevag Gharibian

* Carl Miller
* Mio Murao
* Marco Piani
* Christopher Portmann
* Robert Raussendorf
* Christian Schaffner

Sydney is ridiculous
Sydney is ridiculously picturesque. I snapped this photo just before going to see “The Daughter” at the open air cinema in the Sydney Botanical Gardens. Stunning venue for watching a movie! #nofilter
