Oxford Quantum

This page will eventually become a live list of research papers and other impacts emerging from the Oxford quantum research community. Until that is implemented, here is a flavour of our work: from the start of 2012 to mid-2014 we've produced 29 publications in the Nature and Science families of journals, about one per month (and note that this overlooks top-tier outputs from our computer scientists since they publish elsewhere).

Outreach

The Oxford quantum research community participates in many kinds of outreach, ranging from writing articles for the popular press, through appearances on national radio, to participating in major science shows.

For example in the summer of 2012 we (in collaboration with UCL) put together a huge exhibit for the Royal Society Summer Science Exhibition. It was called Quantum of Spin and was the largest exhibit at the event, with 5 different zones allowing visitors to explore the mysterious sounding phenomenon of quantum spin. The overall exhibit had a James Bond theme, with over ten thousand visitors gambling with quantum-entangled dice, shooting at bad guys with an electromagnet powered “gun”, and writing secret messages to be read by the real, working MRI machine. 

The exhibit was staffed by teams of our staff and students working in shifts.  Over 10,000 visitors passed through the exhibit in the course of the week long event.
