The quantum computing research priorities of Google’s Digital Future Initiative are taking shape, with the search giant announcing four new Australian university partnerships.
National Renewable Energy Laboratory researchers are tackling one of the fundamental problems in quantum information science: how to produce pure elements of quantum information—that is, those that start and remain in a well-defined “spin state”—at practical temperatures.
Research describes observations of silicon ‘T centre’ photon-spin qubits, an important milestone that unlocks immediate opportunities to construct massively scalable quantum computers and the quantum internet that will connect them.
Sensing with levitated nanoparticles has so far been limited by the precision of position measurements. Researchers at the Department of Experimental Physics of the University of Innsbruck, Austria, have now demonstrated a new technique that boosts the efficiency with which the position of a sub-micron levitated object is detected. The new technique demonstrated by Tracy Northup, a professor at the University of Innsbruck, and her team resolves this limitation by replacing the laser beam with the light of the particle reflected by a mirror.
U. Basel researchers have realized a single photon source which allowed them to test the quality and storage time of quantum memory.
A team of researchers led by Richard Warburton at the University of Basel, in collaboration with colleagues at the University of Bochum, has now succeeded in creating identical photons originating from different and widely-separated sources.
Part of the work of the TQN – Theory of Quantum Nanostructures, and many other groups worldwide, is to model quantum systems using conventional computers to crack down the equations.
Experiment demonstrates that quantum key distribution networks, which are part of highly secure cryptography schemes, can also detect and locate earthquakes.
Researchers at Lawrence Berkeley National Laboratory developed a new approach to quantum error mitigation that could help make quantum computing’s theoretical potential a reality: noise estimation circuits.
