[NS] How To Be In Two Places At The Same Time.

An ambitious experiment to make a glass sphere exist in two places at once could provide the most sensitive test of quantum theory yet. The experiment will place a sphere containing millions of atoms – making it larger than many viruses – into a superposition of states in different places, say researchers in Europe.
The idea is to zap a glass sphere 40 nanometres in diameter with a laser while it is inside a small cavity. This should force the sphere to bounce from one side of the cavity to the other. But since the light is quantum in nature, so too will be the position of the sphere. This forces it into a quantum superposition.

I keep thinking of The Flash.

Test vs research, test meaning that if it is possible, we'll find out much sooner.

IDK if I would say this was a waste of time...but I know there are better things that the money and time could be used for...

So if I zap myself and accelerate to the speed of light I will bounce off of anything I hit and be in multiple places at once?

Seriously though this is pretty cool.

Sure, electrons can do it!

No, there is very little that is more important than obtaining and updating our understanding of the basic universe. If, every time we wanted to learn something slightly less short-term optimal than humanitarian desires, we'd never have technologically advanced at all.

...you do realize that computer/GPS/cell phones/LCD TV/ect would not exist today if not for fundamental research done decades ago?


Forcing a large number particles into quantum superposition is another step in understanding this physics. This one day may lead to quantum computing.
