Disorder enhances transport in 1D systems, calculations reveal

Physics World: Under the right conditions, the transport of electrical charges through wires with nanometre-scale thicknesses could become more efficient as disorder in the nanowire increases. This counterintuitive behaviour could be possible following a theoretical discovery made by physicists in Italy…

Transistor-like device controls graphene’s electronic properties

Physics World: Researchers in Germany and Spain have created a transistor-like device that uses a small voltage to control the strength and frequency of electronic signals transmitted through graphene. The feat, which is detailed in Science Advances, marks an important step…

Majorana-based quantum computation gets a handy new platform

Physics World: The errors that arise from the volatile nature of quantum technologies are a major roadblock on the path to practical quantum computing. We can imagine getting past this blockade by driving straight through it, using a car built to…

Job For Particle Accelerators May Be Possible on Tabletop

IEEE Spectrum: Testing whether gravity obeys the laws of classical physics or quantum mechanics is no easy matter. Discovering mineral deposits from space and etching atom-sized lithographs aren’t exactly simple either. But all three tasks may soon belong to a quantum…
