Could a "demon" break one of the most fundamental laws of physics? Maxwell's demon has puzzled physicists for more than 150 ...

For over a century, quantum mechanics has challenged our established notions of physics. At its core are questions that unsettle our understanding of the universe: when does a quantum particle ...

Quantum mechanics and classical physics don't always get along, and can sometimes form apparent paradoxes where observed quantum behavior violates well-established physical laws. In quantum mechanics, ...

It seems quantum mechanics and thermodynamics cannot be true simultaneously. In a new publication, UT researchers use photons in an optical chip to demonstrate how both theories can be true at the ...

Quantum mechanics has always had a way of making even the sharpest minds stop and scratch their heads. In the everyday world, you expect objects to follow straightforward rules. A ball thrown into the ...

The black hole information paradox has puzzled physicists for decades. New research shows how quantum connections in spacetime itself may resolve the paradox, and in the process leave behind a subtle ...

That quantum mechanics is a successful theory is not in dispute. It makes astonishingly accurate predictions about the nature of the world at microscopic scales. What has been in dispute for nearly a ...

For over 100 years now, quantum mechanics has rattled the cage of everything we’ve believed we know about physics. Is everything just made of wiggles and waves if you look close enough? How far can ...

Convention has it that quantum mechanics and thermodynamics cannot be true simultaneously - so say scientists at the University of Twente ("UT"), The Netherlands. But now, in a new journal paper, UT ...
