Computers come in many forms, depending on your definition. We’ve seen computers and computer gates built out of things as diverse as marbles, relays, and — of course — transistor… ...

Logic gate operations. The basic idea of the new logic gate is to encode two binary signals (0 and 1, as is standard in computer logic) in the shape of two few-cycle laser pulses – that is, in their ...

Logic gates process information that we call bits, which come in the form of 0s and 1s. To create the fastest logic gate ever, the researchers used two synchronized laser pulses as the input signals.

Pairs of gates can be used to create AND and OR logic based on the levels of output observed. When a pair of gates are both off, output is low; it's higher for a one-on/one-off situation (OR) and ...

The Boolean logic gates AND, OR and NOT comprise transistors, which are on/off switches wired together. Gates have one or two inputs but only one output, and they are wired in patterns that make ...

We see a lot of discrete-logic computer builds these days, and we love them all. But after a while, they kind of all blend in with each other. So what’s the discrete logic aficionado to do if… ...

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 ...

The new CNOT logic gate, which has been created by Andrew Dzurak, Menno Veldhorst and colleagues at the University of New South Wales and Keio University, has been made by coupling two silicon spin ...

A research team from Skoltech and the University of Wuppertal in Germany determined that an all-optical universal logic gate that was previously developed at Skoltech can operate at a speed of 240 ...
