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.

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

A behind-the-scenes look at how the original handheld digital calculator was created by Jack Kilby’s team of engineers at TI, as told by the grandson of LED inventor James R. ...

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.
