NOT, NAND, NOR, XOR and XNOR). Electronic gates operate on two nominal voltages, normally 0 V and 5 V, representing the logic 0 and the logic 1, respectively. The AND gate has two inputs A and B.

A research team from Skoltech and the University of Wuppertal in Germany determined that an all-optical universal logic gate ...

It’s a surprise then to find that a working CPU can be made with just a single NOR gate — which is what is at the heart of [Dennis Kuschel]’s My4th single board discrete logic computer.

A new breakthrough in optical computing could help make computers dramatically faster. A team of scientists from Skoltech in ...

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 ...
