+==== News ====
+  * 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]].
+  * On May 31, 2015, I will run the 20km of Brussels for [[http://www.medecinsdumonde.be/|Doctors of the World]]. Help me support their action by [[http://www.medecinsdumonde.be/events/20-km-de-bruxelles/j-r-mie_roland|sponsoring my race]].
+  * How to separate information and communication complexity? My joint paper with (too many coauthors to list!), which was accepted at [[http://www.kurims.kyoto-u.ac.jp/icalp2015/|ICALP 2015]], takes a fresh look at this problem: [ [[http://eccc.hpi-web.de/report/2015/028/|http]] ]
+  * 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! [ [[http://arxiv.org/abs/1409.3558|arXiv]] ]
+  * Quantum walks can find a marked element on any graph! The original result was obtained in 2010 with my coauthors Hari Krovi, Frédéric Magniez and Maris Ozols, but the full journal article is finally available in Algorithmica: [ [[http://dx.doi.org/10.1007/s00453-015-9979-8|DOI]] | [[http://arxiv.org/abs/1002.2419|arXiv]] ]
