Exact Quantum Algorithms for the Leader Election Problem
Abstract. It is well-known that no classical algorithm can solve exactly (i.e., in bounded time without error) the leader election problem in anonymous networks. This paper propose...

Bounded-error quantum state identification and exponential separations in communication complexity
We consider the problem of bounded-error quantum state identification: given either state 0 or state 1, we are required to output `0', `1' or `?' ("don't ...

The Search for the Holy Grail in Quantum Cryptography
Abstract. In 1982, Bennett and Brassard suggested a new way to provide privacy in long distance communications with security based on the correctness of the basic principles of qua...

Modelling and Simulation of Quantum Teleportation and Dense Coding Using Predicate/Transition-Nets
Reachability analysis is one of the most successful methods used in design and validation of protocols for classical communication, whereas the predicate/transition-net formalism i...

Loss-Tolerant Quantum Coin Flipping
Coin flipping is a cryptographic primitive in which two spatially separated players, who in principle do not trust each other, wish to establish a common random bit. If we limit ...
