The concept of optical computing is reintroduced with an important new twist — optical computing not as a digital machine, but as an analog engine able to serve as a hardware accelerator for existing ...

A Microsoft analog optical computer has solved two optimization problems and shown potential for AI workloads using less energy.

Understanding the Fundamentals of Analog Computing How Analog Computing Differs from Digital Analog computing stands apart ...

A device that processes infinitely varying signals, such as voltage or frequencies. A thermometer is a simple analog computer. As the temperature varies, the mercury moves correspondingly. A slide ...

The prototype is built from commercially available parts, including micro-LEDs, optical lenses, and sensors from smartphone ...

A new study shows that metamaterials can be designed to do "photonic calculus" as a light wave goes through them. A light wave, when described in terms of space and time, has a profile that can be ...

Microsoft has built a prototype computer that uses light and analog signals instead of traditional binary computing.

Recent progress on both analog and digital simulations of quantum fields foreshadows a future in which quantum computers ...

In 1961, the best general purpose desktop computer money could buy was the Pace TR-48. At just 400 pounds and $25K, the only downside was that it was a little tough to program. That's because the ...
