Optical computing, involving on-chip integrated logic units, could provide improved performance over semiconductor-based computing. Here, a binary NOR gate is developed from cascaded OR and NOT ...

Researchers have now developed the fastest logic gates ever created, by zapping graphene and gold with laser pulses. The new logic gates are a million times faster than those in existing computers ...

A new publication from Opto-Electronic Science; DOI 10.29026/oes.2022.220010 considers optical logic gates in future computers.

Logic gates are the bricks and mortar of digital electronics, implementing a logical operation on one or more binary inputs to produce a single output. These operations are what make all computatio… ...

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" ...

It may seem a paradox, but in the future tiny computers may dump electronics and return to their mechanical roots. At the macroscale, mechanical computers are fussy and slow, but when your area is … ...

The printed logic gates were reliable even after thousands of switching cycles. Velásquez-García explained that manufacturers could use this method in cheap devices that don't need the "best ...

Synthetic biology researchers have demonstrated a new method for digital information processing in living cells, analogous to the logic gates used in electric circuits. The circuits are the ...
