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 ...

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 research collaboration between the University of Bayreuth in Germany and the University of Melbourne has successfully ...

In these systems, tiny individual particles can be reliably trapped to serve as qubits and form quantum logic gates. The Harvard team's paper details the far more complicated process involved with ...

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 ...

Box 1: Criteria for practical optical logic. The electronic transistor and the logic gates based on it have qualitative features that are crucial for systems of any complexity, but very few ...
