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 ...

Researchers at the University of Oxford have achieved a quantum logic gate with record-breaking 99.9% precision, reaching the benchmark required theoretically to build a quantum computer. Quantum ...

(Nanowerk News) In a collaboration between scientists from Physics and Chemistry at the University of Bayreuth and Physical Chemistry at the University of Melbourne, it has now been possible to ...

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 ...
