Harry Buhrman received his Ph.D. from the University of Amsterdam in 1993. His advisors were Peter van Emde Boas and Steven Homer. He is now group leader of the Algorithms and Complexity group at CWI and holds a part-time position as full professor at the University of Amsterdam. His interests include quantum computing, complexity theory, and computational biology.

Oded Regev graduated from Tel Aviv University in 2001 under the supervision of Yossi Azar. He spent two years as a postdoc at the Institute for Advanced Study, Princeton, and one year at the University of California, Berkeley. He is currently with the cryptography group at the École Normale Supérieure, Paris. His research interests include quantum computation, computational aspects of lattices, and other topics in theoretical computer science. He also enjoys photography, especially of his baby girl.

Giannicola Scarpa is a Ph.D. student at CWI, Amsterdam, supervised by Ronald de Wolf. In 2009, he received a Master's degree in Computer Science from the University of Salerno, Italy. His research interests include quantum computing, non-locality, combinatorial optimization, and game theory. In his free time, he is a devoted movie-goer but unsuccessful movie maker, he devours short stories, writes some, and he often claims he is going to lose weight.

Ronald de Wolf received his Ph.D. from the University of Amsterdam and CWI in 2001. His advisors were Harry Buhrman and Paul Vitányi.
