-  * From May 20 to 22, 2015, Stefano Pironio and I organize the 10th Conference on the Theory of Quantum Computation,​ Communication and Cryptography (TQC 2015) in Brussels. More information [[http://​tqc2015.ulb.ac.be|here]].+A 2-year postdoctoral grant and a one-year PhD grant (with possibility of extension) are available as part of a project whose objectives are to study quantum communication complexity and devise explicit quantum protocols for cryptographic primitives such as weak coin flipping. 
 + 
 +Interested applicants should send an email with their resume to jroland (at) ulb.ac.be. Applicants are also encouraged to have at least 2 letters of recommendation arranged to be sent to the same address. 
 + 
 +Consideration of candidates will be effective immediately and will continue until the positions are filled.

   * Any query problem can be solved optimally with bounded error by an adiabatic quantum algorithm, as shown in the article I coauthored with my PhD student Mathieu Brandeho, which was accepted at [[http://​tqc2015.ulb.ac.be|TQC 2015]]. Congratulations to Mathieu for his first accepted article!
