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 ...

Physicists have invented a new type of analog quantum computer that can tackle hard physics problems that the most powerful digital supercomputers cannot solve. New research published in Nature ...

My first job out of college was testing and debugging control loading systems on flight simulators for 747 and the “new” 767 airliners. In the late 1970s, the control loop that simulated the feel of ...

Back in September this year, I wrote a blog on analog computing for AI applications. This followed from ongoing efforts by a few organizations to use analog computing hardware and systems in a ...

A “cheap as chips” open-source Analog Computer can run circles around a Raspberry Pi in solving differential equations and for simulating natural phenomena. To keep costs down, the Anabrid team ...

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 ...

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 ...

Before the era of digital electronic computers, mechanical analog computers were found everywhere. From the relative simplicity of bomb sights to the complexity of fire control computers on 1940s ...

Microsoft has built a prototype computer that uses light and analog signals instead of traditional binary computing. The system, developed in Cambridge, U.K., is designed to handle optimization tasks ...

A SMALL Microsoft Research team has developed an analog optical computer (AOC) that uses light to solve complex optimization and AI problems, aiming for a device that is 100 times faster and 100 times ...
