Quantum Computing

What is quantum computing, what is the promise and what are the challenges?

Quantum computers are extremely complex machines that challenge almost everything we know about computing. Given their complexity, they are difficult to understand which, in turn, makes it difficult for us to understand their limits.

It is said they can crack all modern security algorithms and do immediate pattern recognition. If this is the case, what are the implications for not only computing but also wider society?

Quantum computing provides us with the opportunity to build new algorithms, and to rethink a lot of what has gone before.

Come along and hear the experts delve into this fascinating topic.

Lecture 1: Cryptography after quantum computers

Quantum computers will be able to break some of the most famous and widely deployed cryptosystems. Will our private information be secure in a post-quantum world?

In this talk, Professor Steven Galbraith will briefly survey modern cryptography and indicate which current systems are potentially vulnerable to quantum computers.

Professor Galbraith will then report on recent developments in the area of post-quantum cryptography.

In particular, he will discuss the ongoing National Institute of Standards and Technology (NIST) Post-Quantum Cryptography Standardization process.

Join us for refreshments before each lecture from 6pm at 260.088, Level 0 Foyer, Owen G Glenn Building

About The Speaker

Professor Steven Galbraith is a professor of Mathematics at the University of Auckland and is currently the head of department.

He has a Bachelor of Computing and Mathematical Sciences from the University of Waikato; a Master of Science from Georgia Institute of Technology, USA; and a doctorate from Oxford University in the UK.

He held research positions at Royal Holloway University of London, UK; the University of Waterloo, Canada; the Institute for Experimental Mathematics, Essen, Germany; and the University of Bristol, UK.

He was a lecturer from 2001 to 2009 in the Department of Mathematics at the Royal Holloway University of London, and was made full professor there in 2008.

An international leader in the mathematics of public key cryptography, Professor Galbraith's research is in computational number theory, computational algebraic geometry, and applications in public key cryptography.

He has published around 70 papers and one very large book. Professor Galbraith has given many invited lectures, including being selected by the London Mathematical Society to be the Aitken Lecturer in 2015.
