Researchers at Northwestern University have built a switch that can route qubits, paving the way for quantum networking, and maybe one day (per Wired) a quantum internet.The all-optical switch is capable of routing entangled photons along standard, telecom grade fibre-optic cables, without the entanglement breaking down.
Qubits and Pieces
News from the frontline of the weird and wonderful world of quantum computing. From the theoretical musings of solid state physicists to breakthroughs you might actually see in a data centre in your lifetime, we'll be keeping an eye on stuff that matters in materials science, including graphene, condensed matter, diamonds and so on. And last, but by no mean least, we'll be tracking the spin on spintronics. Just don't mention room temperature.
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.
One of the many interesting things about the cool-by-association-but-also-potentially-very-useful graphene oxide was the fact that it appeared to be soluble. You will be able to tell from the phrasing that it turns out not to be true.
A new technique, developed by a team at Rice University, will allow lithographers to strip back individual, atom-thick, layers of graphene, one at a time, shaping the material into the electronic components it promises to revolutionise.Dr.
Quantum computing may be only just out of the realms of science fiction, but already there is an issue for a standards body to address. Researchers in Austria have come up with a totally new architecture for the exchange of quantum information: quantum antennae.
Brace yourself for a new wave of hard disk sensors and more power efficient hard drives, thanks to the world’s smallest ever magnetic field sensor developed by researchers at the Karlsruhe Institute of Technology and the Institut de Physique et Chimie des Matériaux de Strasbourg (IPCMS).
A kelp-like forest of DNA strands, rooted in sulphur on a bed of gold, turns out to be just the job for filtering electrons according to their spin state. When the strands are long – up to 80 base pairs - the technique is more efficient than magnet-based filters yielding spin polarization of 60 per cent at room temperature.
Researchers in Japan have come up with a new transistor manufacturing technique that they claim will squeeze the best performance enhancements out of carbon nanotubes, without losing the on/off ratio of a good semiconductor.The Nagoya University researchers say they have demonstrated flexible integrated circuits that "are capable of sequential logic" - a first for a transistor made from carbon nanotubes.
Researchers at Princeton University have used graphene to make a new, stable material for building fuel cell catalysts.According to the University’s own paper, the scientists have made a three layer sandwich with platinum nestling between a sheet of graphene and indium tin oxide nanoparticles.
German researchers have developed a new technique for building carbon nano ribbons: instead of slicing up larger sheets of graphene, they are building them, piece by piece, from the bottom up.This has the major advantage of allowing the scientists control over the dimensions of the ribbons.
This week, IBM began something of a band-gap backlash against wunder material graphene. After the computer firm said graphene would never fully replace silicon, a group of scientists in Switzerland announced that there was another two dimensional industrial lubricant with more traditional semi-conductor properties – molybdenum - that could send silicon into retirement.
