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 ...

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, ...

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

MINNEAPOLIS — Don’t try to do a quantum experiment near a black hole — its mere presence ruins all quantum states in its vicinity, researchers say. The finding comes from a thought experiment that ...

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 ...

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 ...

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 ...

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 ...

A puzzle with only three moves may sound simple. In quantum physics, it can still break classical logic. That is the heart of a new experiment led by physicist Zhenghao Liu and colleagues 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 ...
