Lucy Sherriff

Lucy Sherriff is a journalist, science geek and general liker of all things techie and clever. In a previous life she put her physics degree to moderately good use by writing about science for that other tech website, The Register. After a bit of a break, it seemed like a good time to start blogging about weird quantum stuff for ZDNet. And so here we are.

New photon qubit generator 1000x faster than rivals

Scientists in the US have demonstrated a new technique for generating photons for use in optical quantum information processing: using a laser to excite a single photon from a cloud of rubidium gas.The technique, developed at the Georgia Institute of Technology Research, exploits the properties of an atom in which one or more electrons has been excited near ionisation energy levels, the so-called Rydberg state.

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

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

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.
