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 ...

For more than a decade, physicists have argued (and counter-argued) that a subatomic particle can be separated from certain quantum properties, such as its spin—a phenomenon known as the Cheshire cat ...

Hardy's paradox, created in 1992, hinted at a scenario haunting the edges of quantum physics. It presented a thought ...

Classical and quantum mechanics don’t really get along as the science of the subatomic can get, well, weird. Take, for instance, quantum entanglement, which says that the state of one particle can be ...

The original version of this story appeared in Quanta Magazine. Imagine standing on a railway platform watching a trolley go past. A girl on the trolley drops a bright red ball. To her, the ball falls ...

Quantum computing technologies are slowly beginning to trickle out of the laboratory setting and into commercial industries. While it remains to be seen when mainstream adoption will occur, a number ...
