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. |

Quantum Shorts festival announces three film winnersThe Quantum Shorts film festival organised by CQT with international media, scientific and screening partners, has announced its winners. Three films made by directors in Spain, the United Kingdom, and India were awarded prizes for their quantum storytelling on screen. Congratulations to the winners! |
CQT researchers and their US collaborators propose a novel supperadiant laser design that could offer world-class stability in a simple, rugged setup
A surprise twist in their QKD workshop engaged school students, inspiring CQT researchers to publish details of the hands-on demo they designed.

Doing quantum machine learning without going digitalCQT researchers and their collaborators in Greece and China describe a new approach to quantum machine learning. It is a fully analogue scheme rather than digital. The new idea is to use a quantum system’s natural quantum dynamics as a tool to learn complex functions and recognise patterns in data. |
