Logic gate breaks speed record. The chirality logic gates can also be controlled and configured electronically in an electro-optical interface. “Traditionally, the connection between electronic and ...

Nov 15, 2023: Creating optical logic gates from graphene nanoribbons (Nanowerk News) A new graphene-based optical logic gate uses collective oscillations of electrons to process light waves in a far ...

A research team from Skoltech and the University of Wuppertal in Germany determined that an all-optical universal logic gate that was previously developed at Skoltech can operate at a speed of 240 ...

The logic gate is a solid step forward but I just don’t see how that would be an optimal use of such a device; perhaps more akin to virtualization or emulation of a digital electronic computer.

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.

Optical computers have been created before, but they involve complex hardware and are limited to certain applications. Zhang says these new gates can be built from a single layer of molybdenum ...

Sep 28, 2022: Optical logic gates in future computers (Nanowerk News) A new publication from Opto-Electronic Science considers optical logic gates in future computers ("All-optical logic gate ...
