The operation of quantum computers, systems that process information leveraging quantum mechanical effects, relies on the ...

The fun part about logic gates is that there are so many ways to make them, with each approach having its own advantages and disadvantages. Although these days transistor-transistor logic (TTL) is the ...

Find out how a digital technique performs multiplication on two bitstreams and avoids the cost of the analog multiplier.

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, ...
