Way, way back in the day, “computing” was the domain of analog circuits. No, they couldn’t add up columns of numbers, but they could solve complex differential and other equations, and did so fairly ...

Scheme illustration of object identification and all-optical 3D reconstruction system. (a) A contour surface image of the object can be obtained in a single processing of the system. (b) High-contrast ...

Microsoft Research has built a prototype computer that doesn’t rely on electrons zipping through silicon but on beams of light. The machine, called an analog optical computer (AOC), is designed to ...

A team of engineers has proven that their analog computing device, called a memristor, can complete complex, scientific computing tasks while bypassing the limitations of digital computing. A team of ...

With the exponential growth in demand for high-speed data transmission, the 5G system infrastructure, despite its impressive peak data rate of 10 gigabits per second, is increasingly inadequate for ...

(Nanowerk Spotlight) The pursuit of faster and more efficient computing has been a driving force in technological progress for decades. As the demand for computational power continues to grow, ...

A computer that uses light rather than digital switches for calculations could help reduce the energy demands of artificial intelligence (AI), according to a new study. The scientists who invented the ...

Analogue Computing hits the road as editor Andy Turudic uses THe Analog Thing Analog Laptop Computer to simulate an automobile suspension encountering a pothole. Some of you may have already ...

In May, quantum computing was in the news as Google helped fund NASA's Quantum Artificial Intelligence Laboratory to house a D-Wave 2 quantum computer, by paying for the device. In a blog that I wrote ...

You don’t need 0s and 1s to perform computations, and in some cases it’s better to avoid them. Computing today is almost entirely digital. The vast informational catacombs of the internet, the ...
