If gravity is a truly quantum entity, something as simple as measuring the strength of an object’s gravitational field should change its quantum state ...

(It seems like entanglement should allow you to do this, but according to quantum physics this isn't possible. So far, all of our experiments are consistent with that prediction.) But entanglement ...

Berezovsky relishes building experiments that cross quantum weirdness with practical materials science. "We have to grapple with these questions about how the macroscopic world is quantum," he said.

Not that physicists have stopped trying. In their attempts to make sense of quantum weirdness, they have come up with a host of different interpretations of the mathematics at the theory’s heart.

that store and process information at scales where quantum weirdness holds sway 7. When I give talks about quantum computers, every now and then a member of the audience will object that quantum ...

In fact, such a tiny device might make use of the quantum weirdness of the ultra-small. The electron could be coded to have three positions -- instead of simply "on" or "off" it could also have ...
