In order to build the computers and devices of tomorrow, we have to understand how they use energy today. That's harder than ...

We have been taught to think of entropy as a bad thing. "Things fall apart; the centre cannot hold;/Mere anarchy is loosed upon the world," wrote William Butler Yeats in the aftermath of World War I, ...

Can quantum systems become more disordered, as thermodynamics would predict? Yes, they can - if a proper definition of "entropy" is used. It is one of the most important laws of nature that we know: ...

For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other. Quantum theory governs particles and fields, while Einstein’s gravity describes ...

Entanglement is one of the most intriguing features of quantum mechanics. It describes non-local correlations between quantum objects, and is at the heart of quantum information sciences. Entanglement ...

Electron–proton collisions Study reveals importance of entanglement entropy. (Courtesy: Kevin Coughlin/Brookhaven National Laboratory) An international team of physicists has used the principle of ...
