Arxiv – All-optical integrated circuits for computing and information processing have been pursued for decades as a potential strategy to overcome the speed limitations intrinsic to electronics.

As Moore's Law begins to slow, the search is on for new ways to keep the exponential rise in processing speeds going. New research suggests that an exotic approach known as "lightwave electronics" ...

There are a range of integrated circuits that most of us would regard as definitive examples of their type, devices which became the go-to for a particular function and which have entered our ...

Researchers in the UK have taken a small but important step towards the creation of practical quantum computers by creating the first logic gates on a silicon chip that can process individual photons.

Logic signals have fallen from the 15V of the old CMOS 4000 series to 5V TTL (transistor-to-transistor logic) to modern CMOS levels of 3.3, 2.7, and 1.8V. Advanced processes use digital logic that ...

Researchers have built working transistors from graphene nanoribbons less than a nanometer wide, achieving room-temperature ...

Spin doctors: Menno Veldhorst and Andrew Dzurak with their CNOT gate The first quantum-logic device made from silicon has been unveiled by researchers in Australia and Japan. Their controlled-not ...

Logic gates are the fundamental building blocks of computers, and researchers at the University of Rochester have now developed the fastest ones ever created. By zapping graphene and gold with laser ...

It’s time to do a series on logic including things such as programmable logic, state machines, and the lesser known demons such as switching hazards. It is best to start at the beginning — but even ...
