Quantum Games, Honours student project

I just caught up with one of my 2007 Honours students, James Freckleton who did an Honours project with me on Quantum Games. What is that you ask? There is a lot written about quantum games. People seem to have made much hullabaloo that the quantized games give different paybacks than the classical games...but of course...the quantum game is a completely different game and why should it not give different results? James and I instead looked at quantum games from a different viewpoint: can we find quantum games/interactive protocols, which can display a quantum behaviour which is unusual, i.e. by engaging in this interactive protocol the quantum players could achieve some final quantum state which otherwise might be difficult to achieve. We looked at the strange case of the Parrondo game, where classically a player has a choice of several games to play. Each game is, on average, a loosing game and if one repeatedly plays the same game one would loose all one's money. However J. R. Parrondo showed that if one continues to play but switches between the different games (even at random), then one will always wins on average! This paradoxical behaviour has led to such games being known as "Paradoxical games". James F and I looked at various quantum versions of this game and developed the beginnings of a new quantum version of the Parrondo game. With Statistics lecturer Dr David Bulger we are finishing off James's Honours year work and hope to have a paper ready soon. James, who was a Computer Science student here at Macquarie University, just picked up the Avaya Prize for his Honours year work in Computing and is heading off to ANU to do another undergraduate double degree in BSc Science / BSc Science(Psychology)!

Hi Jason, Just stumbled over your blog. I remember Jozef Kosik telling me about the Parrondo game in Bratislava and this paper http://xxx.soton.ac.uk/abs/0704.2937. Derek
