CQT | Centre for Quantum Technologies

A national research centre of excellence

The Centre for Quantum Technologies was established as a national research centre of excellence in Singapore in 2007. We have over 150 scientists and students doing research into the foundations of quantum physics and the ways quantum physics enables new technologies.

CQT to collaborate with government agency IMDA

CQT has signed a Memorandum of Intent with the Infocomm Media Development Authority (IMDA) to develop local technical competencies and promote the development of quantum technologies, in particular, quantum key distribution, in Singapore.

Presenting CQT's Annual Report for 2017

Download the latest annual report of the Centre for Quantum Technologies to learn more about CQT's people, research and events. This edition comes as the Centre reaches its tenth anniverary. The report includes an interview with the Chair of the Centre's Governing Board, stories about our graduates and articles on the future of cryptography, among other topics.

Neglected atom has top properties for atomic clocks

Like watchmakers choosing superior materials to build a fine timepiece, CQT physicists have singled out an atom that could allow us to build better atomic clocks. The team report on the potential of the element lutetium in Nature Communications. “The ultimate performance of a clock comes down to the properties of the atom – how insensitive the atom is to its environment. I would call lutetium top in its class,” says CQT Principal Investigator Murray Barrett.

Reversing cause and effect is no trouble for quantum computers

Research published in Physical Review X shows that quantum computers can more easily model the reversal of cause and effect – like following a movie played backwards - than classical computers. The finding from a team including CQT researchers may have implications for explaining how we perceive time.

Representing quantum at the inaugural Singapore Defence Technology Summit

CQT participated as an exhibitor in the Tech Summit, held 27-29 June. Some 400 delegates including national armament directors, Chief Defence Scientists and captains of industry attended the event.

Design innovations smash a record for photon source brightness

CQT researchers have broken a record for the brightness of an entangled photon pair source, thanks to design improvements reported in Optics Express. In the process, they discovered that scientists have for decades been making such devices more complicated than they needed to be.
