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 computations ...

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 ...

Logic operations – such as NOT, AND, OR and XOR – are carried out in existing electronic circuits by semiconductor devices including diodes and transistors. But the density of electrons flowing ...

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 ...

Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most ...

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 ...

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 ...
