Spin doctors: Menno Veldhorst and Andrew Dzurak with their CNOT gate The first quantum-logic device made from silicon has been unveiled by researchers in Australia and Japan. Their controlled-not ...

In recent years, researchers in the messy world of biology have been able to build systems that function like the clean, binary switches on computer chips—and we've covered a number of reports in this ...

Towards ultrafast logic gates (Courtesy: University of Rochester illustration / Michael Osadciw) The first logic gate to operate at femtosecond timescales could help usher in an era of information ...

Electronics is the manipulation and processing of information using electrons, so it shouldn’t be hard to imagine what the emerging field of atomtronics is attempting to do. The idea is to manipulate ...

There are a range of integrated circuits that most of us would regard as definitive examples of their type, devices which became the go-to for a particular function and which have entered our ...

Computer electronics are shrinking to small-enough sizes that the electrical currents underlying their functions can no longer be used for logic computations in the ways of their larger-scale ...

Silicon nanowires are one of the great hopes for electronic devices of the future. Unlike features carved using photolithography, nanowires are easy to make on a nanometre scale. Electronic engineers ...

Phase change materials can switch between two forms depending on how quickly they’re cooled. Cool them quickly and you get an amorphous form, which provides significant resistance to the flow of ...

One of the hardest things about studying electricity, and by extension electronics, is that you generally can’t touch or see anything directly, and if you can you’re generally having a pretty bad day.
