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, gravity has been the stubborn outlier in physics, resisting every attempt to merge Einstein’s smooth ...

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 ...

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, ...

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 ...

When the constant-depth circuit is removed, the value of topological entanglement entropy (γ) computed from the state returns to the ideal value (γ₀). Credit: Dr. Bowen Shi. In a new study, scientists ...

Entropy is the process of losing energy and this can apply to physics and social systems alike. JamesBrey/iStock via Getty Images Life is full of small decisions: Should I pick up that sock on the ...

Life is full of small decisions: Should I pick up that sock on the floor? Should I do the dishes before bed? What about fixing the leaky faucet in the bathroom? Leaving a sock on the ground is a ...

Cities may be the defining element of human civilization. The path from hunter-gatherers in the Paleolithic era 25,000 years ago to the high-tech, high-wonder jumble we inhabit today runs straight ...
