Mathematicians at the Universities of York, Munich and Cardiff have identified a unique property of quantum mechanical particles – they can move in the opposite way to the direction in which they are being pushed

However, this is no longer true on microscopic scales - quantum particles can partially go into reverse and travel in the direction opposite to their momentum. This unique property is known as 'backflow'.

"These new findings allow us to find out the optimal configuration of a quantum particle that exhibits the maximal amount of backflow, which is important for future experimental verification."


So what's the big deal here? This isn't about quantum particles possibly making super computers, a galactic internet or teleportation. It sounds like they just verified a property that might help other scientists understand the results of their experiments a little better.

Everytime there is a "discovery" like this, the math is shown to be wrong soon after

The stories seem really captivating and awesome up until the point I realize there's no "resulting in....." near the end.
