Analog computers, computing systems that represent data as continuous physical quantities, such as voltage, frequency or ...

Although computers are overwhelmingly digital today, there’s a good point to be made that analog computers are the more ...

Early computers could perform fairly complex calculations just by arranging a few analog circuits. By choosing appropriate resistor and capacitor values, arithmetic summers, integrators, and ...

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 ...

Analog computers were largely phased out once digital systems began to hit the scene, but they’re still used in certain situations because they’re well-suited to complex simulations. Now, a research ...

Scientists have been working toward developing a novel mathematical approach that will help advance computation beyond the digital framework. Your computer performs most tasks well. For word ...

We have analog quantum computers that can be used to solve very specific problems, and several different approaches to general purpose quantum computers, including those with semiconducting qubits, ...

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