Security of Quantum Key Distribution against All Collective Attacks
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 ...

Towards Quantum-Based DB+IR Processing Based on the Principle of Polyrepresentation
The cognitively motivated principle of polyrepresentation still lacks a theoretical foundation in IR. In this work, we discuss two competing polyrepresentation frameworks that are ...

Generalising Unitary Time Evolution
In this third Quantum Interaction (QI) meeting it is time to examine our failures. One of the weakest elements of QI as a field, arises in its continuing lack of models displaying...

From Reversible to Irreversible Computations
In this paper we study the relation between reversible and irreversible computation applicable to different models of computation -- here we are considering classical and quantum ...
