A new publication from Opto-Electronic Science; DOI 10.29026/oes.2022.220010 considers optical logic gates in future computers. If you are reading this on your smartphone, its CPU (central processing ...

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 ...

A technical paper titled “Chirality logic gates” was published by researchers at Aalto University (Finland), National Center for Nanoscience and Technology (Beijing), and University of Cambridge. “The ...

Researchers at Politecnico di Milano and CNR-IFN have demonstrated all-optical logic operations in a tungsten disulfide (WS₂) ...

The basics of digital logic are pretty easy to master, and figuring out how the ones and zeroes flow through various kinds of gates is often an interesting exercise. Taking things down a level and ...

The field of all‐optical logic circuits has garnered significant attention in recent years, particularly with the integration of micro‐ring resonators to process information entirely via light. These ...

We always hear that future computers will use optical technology. But what will that look like for a general-purpose computer? German researchers explain it in a recent scientific paper. Although the ...

It may be possible to reach new levels of miniaturization, speed, and data processing with optical quantum computers, which use light to carry information. For this, we need materials that can absorb ...

(Nanowerk News) A new graphene-based optical logic gate uses collective oscillations of electrons to process light waves in a far smaller space than existing designs. The device also benefits from low ...

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 ...
