A hybrid computer uses rotating mechanical beams for memory and electrical contacts for logic, performing reprogrammable computation through physical motion in environments where conventional ...

Logic gates are the fundamental building blocks of computers, and researchers at the University of Rochester have now developed the fastest ones ever created. By zapping graphene and gold with laser ...

A study on logic gates titled "Light-field control of real and virtual charge carriers" has been published in the journal Nature. Researchers have developed a new kind of logic gate, the fundamental ...

If you are reading this on your smartphone, its CPU (central processing unit) is running at its full speed. It is a tiny chip containing billions of the more basic units called logic gates. In the ...

Researchers at the University of Rochester and the Friedrich-Alexander-Universität Erlangen-Nürnberg have created the fastest logic gates ever. If the process is ever brought to market, the ...

As Moore's Law begins to slow, the search is on for new ways to keep the exponential rise in processing speeds going. New research suggests that an exotic approach known as "lightwave electronics" ...

Logic gates are the fundamental components of computer processors. Conventional logic gates are electronic – they work by shuffling around electrons – but scientists have been developing light-based ...

The processor in a quantum computer. The quantum chip contains the qubits as well as the quantum logic gates that manipulate the qubits. This differs dramatically from a classical computer where the ...

Forward-looking: Semiconductors are essential for today's electronics, providing computational capabilities and the ability to control electric signals. They are also highly complex and costly, so ...

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 ...
