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.

Trained for the workplace

 

“After the first couple of years of my PhD, I knew I wanted to go into something where I could apply the knowledge I had been picking up,” says Sambit Pal, who graduated in 2017 and is now Chief Technology Officer for a company he co-founded. Like Sambit, many CQT alumni have taken their scientific skills into new types of roles. Working across a wide range of industries, CQT alumni can be found in banking, consulting, and in technical jobs including data science and engineering. Hear their stories.

Play the Quantum Game with Photons

 

A sentient rock wants the laser off its face. A Venus flytrap is hungry for light. By adding just two mirrors, can you humour the rock and feed the flytrap? This puzzle is one of the first levels of the new Quantum Game with Photons 2, which features cute quantum components that follow accurate physics. Developed by a team of scientists, programmers and designers with support in 2019 from CQT, the educational game is now seeking players - and their feedback.

Match-making between photon and atom frequency could boost quantum network performance

CQT researchers demonstrate a novel scheme to compress the frequency spread of single photons using a resonant cavity and time-lenses. This is a promising approach to make light-matter interactions in quantum technologies more efficient.
