Formal Security in Quantum Cryptology

Formal Security in Quantum CryptologyD. Unruh (thesis, 2002).  [eprint]

Abstract: The objective of this work is to introduce the notion of formal security into quantum computation. In order to achieve this, we introduce a new security model, containing a quantum communication model. We will lay some stress on formal details to show which are the problems arising in a formal definition of quantum security.

Based on this model we will analyse some basic aspects of quantum protocols:

Both questions we will answer by and large positively. This discussion (and especially the proofs) will be less formal, because of the complex nature of the underlying communication processes.
