Etch-A-Sketch inspires single electron transistor
Researchers at the University of Pittsburgh, HP Labs and UW Madison, have built a single electron transistor that will operate with the addition of just one or two more electrons.The new device, hailed as a potential building block for ever smaller and denser memory devices, and even quantum computers, was created with an atomic scale "Etch-a-Sketch" developed by Prof.
Nobel prize winner waves magnetic wand over graphene
Professor Andre Geim, one of the researchers awarded the Nobel prize for his work with Graphene, announced yesterday that he and his team at the University of Manchester have successfully magnetised graphene using a flow of electrons.The work has been described as a potentially huge breakthrough in the field of spintronics, as it "offers numerous opportunities for redesigning current spintronics devices and making new ones such as spin-based transistors" per the university’s announcement.
IBM clocks graphene transistor at 155GHz
IBM has demonstrated a new super whizzy graphene transistor, clocking in at 155GHz, up from the 100GHz it benched last year.The breakthrough was made possible because the transistor was set on a substrate of "diamond-like carbon", itself layered on a commercial silicon wafer.
Graphene adds self-cooling to list of super powers
Graphene, twice threatened by silicon's atom-thick offspring silicene, the pretender to its carbon throne, has hit back with yet another amazing characteristic: transistors made from the atom-tick carbon mesh will cool themselves.Heat is the bane of the electronics industry’s life.
Physicists set new quantum entanglement world record
Physicists at the University of Innsbruck report a world record in quantum computing: controlled entanglement of 14 atoms to produce 14 qubits, the largest quantum register ever produced.We hesitate in bringing you this news, as the press release is dated April 1st.
Silicene raises new challenge to graphene's throne
Graphene's chief rival silicene, has been given another boost as scientists in Japan have found a new way to manufacture atom-thin sheets of silicon.The idea that silicon could exist in two dimensional sheets was first mooted back in 2007, when researchers from Wright University in Ohio dubbed the then hypothetical material “silicene”.
Quantum switch keeps photons tangled in fibre
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.
Antennae signal new qubit architecture
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.
Who needs lithography? Read data with organic molecules
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).
