All-optical logic gates constitute a pivotal advancement in photonic computing, where Boolean operations are executed entirely by light rather than by electrical signals. This technology exploits ...

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 ...

A logic gate is an electronic component (or set of them) that performs a logic operation, in which the binary values 0 and 1 are represented with two different voltage values, as seen in the previous ...

The previous article examined the concept of logic gates. They can be made from discrete and active electronic components, although today logic gates are available within integrated circuits. In this ...

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 ...

Towards ultrafast logic gates (Courtesy: University of Rochester illustration / Michael Osadciw) The first logic gate to operate at femtosecond timescales could help usher in an era of information ...

In the race to build powerful quantum computers, many groups are competing to build logic gates that can process quantum information and still be connected together on a large scale. One important ...

(a)Working principle of the spin logic device. (b) Transition among diverse magnetic configurations in this heterojunction. By manipulating the direction of the Oersted field, the SOT-induced ...

Logic gates are the fundamental building blocks of computers, and researchers at the University of Rochester have now developed the fastest ones ever created. By zapping graphene and gold with laser ...
