Researchers spin ‘wheel of fortune’ to land big prize: a fundamental proof of quantum mechanics
Researchers from CQT and University of New South Wales (UNSW) Sydney have proven fundamentally that a spinning atomic nucleus really is a quantum resource. The new work is published in the journal Newton.

Dieter Schwarz Foundation establishes Professorship for Technology Partnership with NUS
The Dieter Schwarz Foundation has pledged to establish a groundbreaking research and development programme at CQT. The newly established Dieter Schwarz Foundation Professorship in Quantum Communication & Security will propel research, education and innovation in quantum science and engineering at NUS.

CQT Principal investigator Christian Kurtsiefer and former group member Shen Lijiong have demonstrated a way to close a potential security loophole in the performance of single-photon detectors.

Singapore has joined the Global Network of Optical Magnetometers to search for Exotic physics (GNOME).

Researchers prove limit on entanglement assisted communication
Researchers have long known that entanglement can boost the amount of information that can be communicated from a sender to a receiver, but not by how much. CQT’s Marco Tomamichel and his collaborators give an answer in their new work published in Physical Review Letters.
