New Records Set for Silicon Quantum Computing

New Records Set for Silicon Quantum Computing

Two research teams working in the same laboratories at UNSW Australia have found distinct solutions to a critical challenge that has held back the realisation of super powerful quantum computers.   The teams created two types of quantum bits, or “qubits” — the building blocks for quantum computers — that each process quantum data with [...]

Circuits That Melt Away When You’re Done

Circuits That Melt Away When You’re Done

Electronic devices that dissolve completely in water, leaving behind only harmless end products, are part of a rapidly emerging class of technology pioneered by researchers at the University of Illinois at Urbana-Champaign. Early results demonstrate the entire complement of building blocks for integrated circuits, along with various sensors and actuators with relevance to clinical medicine, [...]

Graphene: When a Doughnut Becomes an Apple

Graphene: When a Doughnut Becomes an Apple

In experiments using the wonder material graphene, ETH researchers have been able to demonstrate a phenomenon predicted by a Russian physicist more than 50 years ago. They analysed a layer structure that experts believe may hold unimagined promise.   Anastasia Varlet works as a doctoral candidate in the research group headed by ETH Professor Klaus [...]

Quick-Change Materials Break Silicon Speed Limit for Computers

Quick-Change Materials Break Silicon Speed Limit for Computers

Faster, smaller, greener computers, capable of processing information up to 1,000 times faster than currently available models, could be made possible by replacing silicon with materials that can switch back and forth between different electrical states.   The present size and speed limitations of computer processors and memory could be overcome by replacing silicon with [...]

Moving Silicon Atoms in Graphene

Moving Silicon Atoms in Graphene

Richard Feynman famously posed the question in 1959: is it possible to see and manipulate individual atoms in materials? For a time his vision seemed more science fiction than science, but starting with groundbreaking experiments in the late 1980s and more recent developments in electron microscopy instrumentation it has become scientific reality. However, damage caused [...]

Electronics That Need Very Little Energy?

Electronics That Need Very Little Energy?

A team of researchers has discovered a way to cool electrons to -228 °C without external means and at room temperature, an advancement that could enable electronic devices to function with very little energy.   A chip, which contains nanoscale structures that enable electron cooling at room temperature, is pictured. The process involves passing electrons [...]
