Why do computers only work with the numbers 0 and 1? There are machines that process three digits with more efficiency than ...

Don’t feel like shelling out $5 for a fancy factory made calculator that won’t even do binary math? [Jeff] decided to prove his mastery of gates and his disdain for base 10 by building a ...

Most of us can do simple math in our heads, but some people just can’t seem to add two numbers between 0 and 3 without using paper, like [Aliaksei Zholner] does with his fluidic adder circuit… ...

As the simplest way of implementing optical logic gates, spatial coding of optical field has been proposed very early in the 1970s and 1980s.

Optical computing, involving on-chip integrated logic units, could provide improved performance over semiconductor-based computing. Here, a binary NOR gate is developed from cascaded OR and NOT ...

Learn about digital data and how computers understand it, including binary, denary, hexadecimal numbers, units of data, character sets and logic gates.

Excess-3 Binary Logic To perform arithmetic operations on the numbers keyed into the calculator, each individual number was converted into a 4-digit binary (1s and 0s) form known as excess-3 (XS-3).

A team of engineers at the University of New South Wales has built the first two-qubit logic gate in silicon, bringing the world another step closer to quantum computing.

The binary code of 0 or 1 is then indicated by the 'spin' of the electron. Previously it wasn't possible to get two quantum bits to 'talk' to each other - and thus create a logic gate - using silicon.
