Building logic gates out of silicon is old hat ... crab-based system of computation couldn’t be expanded to a (very) basic calculator.

Logic gates are the bricks and mortar of digital ... Although these seven gates are normally considered the “basic” gates, there are some gates, such as the NAND gate, that are universal ...

In its most basic form, a computer is a collection of powered and unpowered circuits and transistors. A logic gate is a series of transistors connected together to give one or more outputs ...

A fully optical logic gate could allow us to transition ... used these optical logical gates to process basic information purely using light. According to Phys.org, the team ran several read ...
