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, ...

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 ...

Scientists can’t prove time travel is possible, but they are testing its core principles using quantum and mathematical ...

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 ...

A research team has achieved the loophole-free test of Hardy's paradox for the first time. The team successfully demonstrated Hardy's nonlocality while closing both the detection efficiency loophole ...

In an exper­i­ment car­ried out in 2009, our group has performed a quantum simu­la­tion of the Dirac equa­tion using a single trapped ion and observed so called Zitter­be­we­gung, a pecu­liar ...

New series: short, bite-sized summaries of important scientific topics — this is the first episode. Chapters 0:00 The force of gravity 1:58 The universe is Quantum, that's a problem! 4:32 String ...

It looks like time travel, closed timelike curves, quantum mechanics, and quantum entanglement are once again at the centre of discussions among scientists who recently came up with a new way to send ...

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 ...

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 ...

I don’t know about ‘quantum healing’ or ‘quantum golf’, but I started to think about a possible connection between quantum theory and how people use concepts in 1998 when I was talking to a graduate ...

The properties of quantum mechanics have long puzzled physicists—even Albert Einstein once described quantum entanglement as “spooky action at a distance.” That’s because quantum mechanics, at least ...
