Could Aluminum Nitride Be Engineered to Produce Quantum Bits?

Graphical_Abstract_AlN_Sci_Rep_no_logo1.jpg

The leading method for creating quantum bits, or qubits, currently involves exploiting the structural defects in diamonds. But using NERSC resources, University of Chicago researchers found that the same defect could be engineered in cheaper aluminum nitride. If confirmed by experiments, this could significantly reduce the cost of manufacturing quantum technologies.

Atoms Placed Precisely in Silicon Can Act as Quantum Simulator

In a proof-of-principle experiment, researchers at UNSW Australia have demonstrated that a small group of individual atoms placed very precisely in silicon can act as a quantum simulator, mimicking nature - in this case, the weird quantum interactions of electrons in materials.

Physicists Build Engine Consisting of One Atom

113382_web.jpg

An article in the latest edition of the journal Science describes an innovative form of heat engine that operates using only one single atom. The engine is the result of experiments undertaken by the QUANTUM work group at the Institute of Physics of Johannes Gutenberg University Mainz (JGU) in collaboration with theoretical physicists of Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU).

Russian Scientists Develop Long-Range Secure Quantum Communication System

113028_web.jpg

A group of scientists from ITMO University in Saint Petersburg, Russia has developed a novel approach to the construction of quantum communication systems for secure data exchange. The experimental device based on the results of the research is capable of transmitting single-photon quantum signals across distances of 250 kilometers or more, which is on par with other cutting edge analogues. The research paper was published in the Optics Express journal.

Unlocking the Gates to Quantum Computing

111499_web.jpg

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.
