A national research centre of excellence

 

The Centre for Quantum Technologies was established as a research centre of excellence in Singapore in 2007. We have some 180 staff and students doing research into the foundations of quantum physics and the ways quantum physics enables new technologies.

Improved security analysis for quantum communications from space

CQT’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 design

Designers 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.

Novel superradiant laser promises to make ultrastable light sources practical

CQT 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.
