After the successful Industry Sessions held at the previous QIPC meetings in Barcelona’07 and Rome’09, the event at QIPC'11 again offered a platform for exchanges between academic researchers and industry leaders.

There were presentations by Dr. Bruno Michel, from IBM Research, Zürich, who talked about 'Computing after scaling: New computation paradigms', and Dr. Grégoire Ribordy, CEO of ID Quantique, who are celebrating their 10th anniversary this year. The title of his presentation was accordingly 'Commercializing QITechnology for 10 years'.

Bit commitment is a fundamental cryptographic primitive with numerous applications. Quantum information allows for bit commitment schemes in the information theoretic setting where no dishonest party can perfectly cheat. The previously best-known quantum protocol by Ambainis achieved a cheating probability of at most 3/4, while Kitaev showed that no quantum protocol can have cheating probability less than 1/sqrt{2}. Closing this gap has since been an important and open question. In this paper, the authors provide the optimal bound for quantum bit commitment.

According to quantum theory, measurements generate random outcomes, in stark contrast with classical mechanics. This raises the question of whether there could exist an extension of the theory that removes this indeterminism, as suspected by Einstein, Podolsky and Rosen. Although this has been shown to be impossible, existing results do not imply that the current theory is maximally informative. Here we ask the more general question of whether any improved predictions can be achieved by any extension of quantum theory.

We are happy to announce that, by decision of the QUIE2T Advisory Board of Experts and upon approval by the QUIE2T Coordination Steering committee, the

2011 European Quantum Information Young Investigator Award

has been awarded jointly to
