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 ...

(Nanowerk News) The field of metamaterials has produced structures with unprecedented abilities, including flat lenses, invisibility cloaks and even optical "metatronic" devices that can manipulate ...

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, ...

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 ...

Many of the most exciting properties of materials arise due to interactions between electrons. Correlations between electrons' spins are involved in magnetism and may be responsible for ...

Machine-learning forms of artificial intelligence are going to produce a revolution in computer systems, a new kind of hardware-software union that can put AI in your toaster, according to AI pioneer ...
