First demo of quantum switching network claimed

First demo of quantum switching network claimed

Researchers at the Max Planck Institute of Quantum Optics (MPQ) are claiming a world first with a demonstration of a quantum switching network. The Institute reports data being exchanged successfully "with high efficiency and fidelity" between two quantum nodes installed in two separate labs, connected by a 60-metre long optical fibre.

Researchers generate flying qubits in semiconductors

Researchers at Ruhr-Universitat Bochum report the creation of electron qubits in semiconductors. So far, the team says, electron qubits have all been created in a vacuum, so this development really does look like a next step on the oft-mentioned road to quantum computing.

Stanford squeezes piezoelectricity out of graphene

As if its list of properties was not already impressive enough, materials scientists working with sophisticated computer models at Stanford University have added another useful trick to graphene’s repertoire: they have made it piezoelectric."We thought the piezoelectric effect would be present, but relatively small.

Graphene coated DVD + LightScribe = Supercapacitor

Graphene coated DVD + LightScribe = Supercapacitor

Scientists at UCLA have put a Lightscribe DVD optical drive to work in their graphene research, and have used them to produce a graphene-based electrochemical supercapcitor that could make itself very useful in a world ever more dependent on battery power.In a paper published in the March 16 edition of the journal Science, the researchers explain that electrochemical capacitors have attracted a lot of interest because they can be charged and discharged much faster than traditional batteries.

Impure thoughts to improve spintronics materials

Impure thoughts to improve spintronics materials

Researchers at Berkeley Lab have discovered that they can control the Curie temperature, and hence the magnetism of the semiconductor gallium manganese arsenide (GaMnAs). The breakthrough settles a long running controversy over the usefulness of the material in the emerging field of spintronics.

Scientists propose self-cooling nano-speaker for MRIs

Theoretical physicists working at Harvard and the Joint Quantum Institute in the US have joined forces with their Danish colleagues at the Niels Bohr Institute, to design a nanoscale loud speaker that could help make MRI scanners smaller, and might one day find a use in a future quantum computer.The 'speaker' they have conceived still needs to be tested experimentally.
