Scientists have established a relationship between the complexity of a problem, and the physical processes of entanglement required to solve it. “Some mathematical problems are easy. Some mathematical ...

Empowered by artificial intelligence technologies, computers today can engage in convincing conversations with people, compose songs, paint paintings, play chess and go, and diagnose diseases, to name ...

There are different ideas about how quantum computers could be built. But they all have one thing in common: you use a quantum physical system - for example individual atoms - and change their state ...

The oversampling regime of an exemplary clock—a pendulum in a weakly lit environment. The two sources of entropy production for this clock are: the friction within the clockwork itself, and the matter ...
