Computers use transistor-based logic gates as the basis of their functions, but molecular logic gates would make them much faster. A report of DNA-based logic gates could be a first step towards ...

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

However, even the largest 64-pin devices only provide six logic gates, and in the 48-pin packages it seems that only five of these are actually available on I/O pins.

Using DNA and harmless gut bacteria, scientists at Imperial College London have built biological logic gates that could lead to the development of a new generation of microscopic biological ...

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 ...

New optical chirality logic gates developed by researchers at Aalto University operate about a million times faster than existing technologies, offering ultrafast processing speeds.

Made up of a few transistors apiece, logic gates accept two bits—1s or 0s—as inputs and, according to a rule determined by their specific pattern of transistors, output a single bit.
