Improved security analysis for quantum communications from spaceCQT’s Charles Lim and Artur Ekert report with experimentalist colleagues from China a more efficient security proof method for short keys. The improved analysis could be particularly useful for satellite-based quantum communication systems, which typically operate with slower data rates than their terrestrial counterparts. |

Machine learning technique could aid photonic crystal designDesigners of photonic crystals might be able to better predict the properties of new light-controlling materials with an approach proposed by CQT Senior Research Fellow Daniel Leykam and Principal Investigator Dimitris Angelakis. The approach uses a technique from machine learning known as ‘persistent homology’ and could make it easier to design man-made photonic crystals for specific applications. |
A surprise twist in their QKD workshop engaged school students, inspiring CQT researchers to publish details of the hands-on demo they designed.

Novel superradiant laser promises to make ultrastable light sources practicalCQT researchers and their US collaborators predict that hot atomic beams could offer world-class laser stability in a simple, rugged setup. “The idea is to democratise ultrastable lasers,” says CQT PI Travis Nicholson, co-author on the paper in Physical Review Letters. |
