While digital computers have become entrenched in our daily lives, a new analog quantum computer offers a stark contrast in both its design and capabilities. A team of physicists from Stanford ...

Although computers are overwhelmingly digital today, there’s a good point to be made that analog computers are the more efficient approach for specific applications. The authors behind a recent paper ...

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 ...

This component has an aluminum frame and three gears on top. It appears to have two similar mechanisms on the inside – each includes a shaft, a screw with linkages, and a cylinder turned by rotating a ...

Our new tech editor for Analog looks at the evolution of “analog” and how it inadvertently spun off a pop music genre. Operational Amplifiers are exactly that—amplifiers that can perform mathematical ...

Comparing digital compute with analog compute What strides have been taken to make analog a better alternative to digital? How deep neural networks come into play. In 1974, Theodore Nelson, the ...

When your only tool is a hammer, everything starts to look like a nail. That’s an old saying and perhaps somewhat obvious, but our tools do color our solutions and sometimes in very subtle ways. For ...

I'm sure nearly everyone has by now heard that Google “proved” the D-Wave 2 they operate jointly with NASA (mainly paid for by Google) can operate “up to ∼ 10 8 times faster”. If not, you might want ...
