Researchers in the UK have taken a small but important step towards the creation of practical quantum computers by creating the first logic gates on a silicon chip that can process individual photons.

We’ve always been fascinated at the number of ways logic gates can spring into being. Sure, we think of logic gates carrying electrons, but there are so many other mechanical means to do the same ...

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 ...

Light-based logic: The optical chirality logic gate is made of a nonlinear optical material that generates an output signal that’s dependent on the chirality of the two input beams. (Courtesy: Yi ...

The fun part about logic gates is that there are so many ways to make them, with each approach having its own advantages and disadvantages. Although these days transistor-transistor logic (TTL) is the ...
