Entangled keys sent over Singtel fibre

 

CQT researchers from the NUS-Singtel Cyber Security Laboratory have performed the first quantum key distribution (QKD) demonstration over commercial fibre in Singapore. “This is one of the steps to move QKD from research to applications – to assess the impact of environmental factors you have in deployed telecom fibre,” says CQT Principal Investigator Christian Kurtsiefer.

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.

Doing quantum machine learning without going digital

CQT 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.
