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 ...

Researchers have demonstrated the first complete set of logical quantum operations on a silicon-based processor, encoding information across five nuclear spins of phosphorus donor atoms using the ...

Why it matters: For decades, scientists have dreamed of building computer chips that use light instead of electricity to process information. While our current silicon chips are incredibly fast, ...
