Joe will be giving the monthly colloquium at Centre for Quantum Technologies on Thursday, May 18th. The talk will be at 4pm in the CQT Seminar Room.

Secure Quantum Computation

The realisation that conventional information theory and models of computation do not account for the full generality of states and operations described by quantum mechanics has led to the burgeoning field of quantum information processing. By harnessing quantum phenomena it is possible to produce stronger forms of cryptography and more efficient algorithms than could exist in a purely classical world. Computer security lies at the intersection of computation and cryptography, and has become an increasingly important topic in recent years. Since quantum information processing leads to advantages in cryptography and computation separately, it is natural to ask whether it may also enhance computer security. In this talk I will argue that the answer to this question is a resounding “yes”, and discuss recent developments in the field.
