The operation of quantum computers, systems that process information leveraging quantum mechanical effects, relies on the ...

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 ...

Light-based logic: The optical chirality logic gate is made of a nonlinear optical material that generates an output signal that’s dependent on the chirality of the two input beams. (Courtesy: Yi ...

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 ...

Scientists have for the first time demonstrated improvement in quantum computers by using codes designed to detect and discard errors in the logic gates of such machines. The codes were applied to IBM ...

A long-standing quest for science and technology has been to develop electronics and information processing that operate near the fastest timescales allowed by the laws of nature. A promising way to ...

Memristors, a type of circuit element based on magnetic flux, were first proposed back in 1971, but remained limited to the realm of theory until 2008. That's when some researchers from HP Labs ...

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 ...

(a)Working principle of the spin logic device. (b) Transition among diverse magnetic configurations in this heterojunction. By manipulating the direction of the Oersted field, the SOT-induced ...
