According to computational complexity theory, mathematical problems have different levels of difficulty in the context of their solvability. While a classical computer can solve some problems (P) in ...

Storage, computation, and communication are the three pillars of modern information technology, with computation being the central aspect. The von Neumann architecture, based on the Turing machine ...

WEST LAFAYETTE, Ind. — “You see, nature is unpredictable. How do you expect to predict it with a computer?” said American physicist Richard Feynman before computer scientists at a conference in 1981.

The phenomenal success of our integrated circuits managed to obscure an awkward fact: they're not always the best way to solve problems. The features of modern computers—binary operations, separated ...

Scientists have developed a mathematical description of what happens within tiny magnets as they fluctuate between states when an electric current and magnetic field are applied. Their findings could ...

As the barriers to CPU scaling have risen with each successive node shrink, the number of scientists looking for alternate methods of driving higher performance and/or saving power has also steadily ...

Nanoscale device employs magnetic tunnel junctions to convert thermal noise into binary signals for random number generation.

A new computing paradigm—thermodynamic computing—has entered the scene. Okay, okay, maybe it’s just probabilistic computing by a new name. They both use noise (such as that caused by thermal ...

Researchers demonstrate how skyrmions can be used for future computer concepts that are closer to how the human brain works. Working group led by physicist Professor Ulrich Nowak at the University of ...
