Optical logical operations have sparked major interest in the past decades since it can enable many applications, particularly those involving high-throughput and on-the-fly data processing such as ...

With transistors and logic gates as our basic building blocks, we can begin to construct the actual circuits that make up computer memory. One of the simplest memory circuits is the AND gate, which ...

If the planet Vulcan had microbes, they might look something like this. Scientists have engineered bacteria that can perform four basic operations of logic: AND, OR, NAND and NOR. By combining these ...
