International Research Group Elucidates Dynamics of Quantum Spin Orbital Liquid

An international research group observed a state in copper oxides in which orbital degrees of freedom did not freeze at low temperatures and electrons fluctuated due to quantum fluctuations. The group also clarified the time scale of these quantum fluctuations in multifrequency electron spin resonance (ESR) experiments in a strong magnetic field for the first time.

Researchers Overcome a Key Challenge to Quantum Computing

Researchers from Griffith University and the University of Queensland have overcome one of the key challenges to quantum computing by simplifying a complex quantum logic operation. They demonstrated this by experimentally realising a challenging circuit -- the quantum Fredkin gate -- for the first time.

Breakthrough in Generating Single Photons as Carriers of Quantum Information in Security Systems

An international team of researchers has made a breakthrough in generating single photons – the single quanta of light particles – as carriers of quantum information in security systems. The findings are set to revolutionise cybersecurity, along with advancing quantum computing, which can search large databases exponentially faster. Work will be continued through the Australian Institute for Nanoscale Science and Technology, which launches at the University of Sydney in April 2016.
