Classical Trajectories for two Ring-Shaped Potentials

M. Kibler, G. -H. Lamot, P. Winternitz

This paper deals with the classical trajectories for two super-integrable systems: a system known in quantum chemistry as the Hartmann system and a system of potential use in quant…

Unextendible Product Bases and Bound Entanglement

C. H. Bennett, D. P. DiVincenzo, T. Mor +3

An unextendible product basis (UPB) for a multipartite quantum system is an incomplete orthogonal product basis whose complementary subspace contains no product state. We give exam…

Defeating classical bit commitments with a quantum computer

Gilles Brassard, Claude Crépeau, Dominic Mayers +1

It has been recently shown by Mayers that no bit commitment scheme is secure if the participants have unlimited computational power and technology. However it was noticed that a se…

Quantum Counting

Gilles Brassard, Peter Hoyer, Alain Tapp

We study some extensions of Grover's quantum searching algorithm. First, we generalize the Grover iteration in the light of a concept called amplitude amplification. Then, we show…

No-cloning of Orthogonal States in Composite Systems

Tal Mor

The no-cloning principle tells us that non-orthogonal quantum states cannot be cloned, but it does not tell us that orthogonal states can always be cloned. We suggest a situation w…

Security of Quantum Key Distribution Against All Collective Attacks

Eli Biham, Michel Boyer, Gilles Brassard +2

Security of quantum key distribution against sophisticated attacks is among the most important issues in quantum information theory. In this work we prove security against a very i…
