Building logic gates out of silicon is old hat, as is building them from discrete transistors, 555 chips, LEGO, and even gears. [Yukio-Pegio Gunji] and [Yuta Nishiyama] from Kobe University ...

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 ...

Welcome back to the second part of our beginner’s guide to understanding the quantum revolution. If you’ve read the first ...

In the 1960s, the study of the physics of computing rapidly focused on the fundamental minimal operation required — the Boolean logic gates. Rolf Landauer 12 showed that the energy needed to ...

Logic gates have one or two 0 or 1 inputs but only one 0 or 1 output as in the following examples. Transistors make up gates, gates make up circuits, and circuits make up electronic systems.

A single digital signal has only two states - on or off. However, if you use two inputs you can double the number of possible states, to four.

A research collaboration between the University of Bayreuth in Germany and the University of Melbourne has successfully devised an optically switchable photonic unit for storing and reading binary ...

An AND gate usually has two inputs. AND tells us that both Input A AND Input B have to be 1 (or ON) in order for the output to be 1. Otherwise the output is 0.

A chip that contains one logic gate or a small number of logic gates. Although thousands of gates are routinely placed on a single chip, discrete logic chips with only one or two gates are also ...
