Ultrafast control of spins in a microscope

Researchers at EPFL have developed a new technique that can visualize and control the rotation of a handful of spins arranged in a vortex-like texture at the fastest speed ever achieved. The breakthrough can advance "spintronics," ...

New spin control method brings billion-qubit quantum chips closer

Australian engineers have discovered a new way of precisely controlling single electrons nestled in quantum dots that run logic gates. What's more, the new mechanism is less bulky and requires fewer parts, which could prove ...

Spinning out the future of our electronic devices

To satisfy the world's desire for ever more processing power, at ever diminishing energy cost, in even tinier devices, scientists are looking to spintronics (spin transport electronics) to provide the next generation of high-speed, ...

Highly energy-efficient CMOS logic systems

Non-volatile bistable memory circuits being developed by Satoshi Sugahara and his team at Tokyo Tech pave the way for highly energy-efficient CMOS logic systems. The details are described in the February 2013 issue of Tokyo ...

Lightweight true random number generators a step closer

The widespread use of true random number generators (TRNGs) has taken a step closer following the creation of the most lightweight designs to date by researchers at Queen's University Belfast's Institute of Electronics, Communications ...
