CQT researchers contributed to a recent paper in Science reporting Bell correlations in a Bose-Einstein condensate. Getting the result was an interdisciplinary effort, which added to the challenge. The authors come from two different communities – quantum information and many-body physics.

CQT's Valerio Scarani says "We discovered that the two communities would be looking for different pieces of information, both in the text and in the data presented, and we had to find a compromise that would make the paper convincing for both."

The experiments were carried out at the University of Basel in Switzerland.

Scientist Mile Gu is returning to CQT as a fellow of Singapore's National Research Foundation to work on projects that bring together complexity and quantum science. 

"At first glance these fields seem to have little in common. Quantum systems are microscopic, complex systems are macroscopic interacting systems like economies or climate. But these two sciences both use the common language of information theory," says Mile, "some of the tools map between them."

Four stories from over 400 entries have claimed prizes in our Quantum Shorts contest for flash fiction inspired by quantum physics. Read them here:
What if checking for monsters under your bed doomed a parallel you to a grisly end? A story that explores this fear of a girl aged six and three quarter years has won the 2015 Quantum Shorts international competition for flash fiction inspired by quantum physics. “Ana” by Liam Hogan was selected ...

So much for the belief that thinner is better. Researchers at CQT have shown that when it comes to making pairs of correlated light particles, a thick crystal can work just as well as a thin one.

This is the first research paper of first author Brigitta Septriani. "I never thought that I would be able to contribute to science. Doing systematic research is a striking experience for me," she says. Brigitta first joined CQT to do an undergraduate project. She was appointed a Research Assistant after she completed her degree.

Congratulations Brigitta!

The findings are published in Optica: https://www.osapublishing.org/optica/abstract.cfm?uri=optica-3-3-347

On Thursday this week we're hosting Gregory Chaitin from the Federal University of Rio de Janeiro to give a colloquium: "Leibniz on Complexity"

His abstract: "2016 is the tercentenary of the death of the remarkable philosopher/mathematician Leibniz. In this talk we shall present an appreciation of his work on information, computation and complexity leading up to modern work on algorithmic information and conceptual complexity, with applications in epistemological critiques of physics, mathematics and biology."

The talk will be 4pm at CQT's seminar room. All welcome!

Could laser-powered superconductors spark a technological revolution?

CQT Visiting Prof Dieter Jaksch, also at the University of Oxford, is co-author on a Nature paper reporting evidence for a light-induced superconducting phase in a material made of buckyballs and potassium: http://www.nature.com/nature/journal/vaop/ncurrent/full/nature16522.html

Co-author and CQT alumnus Stephen Clark, now at the University of Bath, explores the context in an article for The Conversation:
