Earth sabotages quantum tests

摘要

It's been holding us back as well as holding us down. A previously overlooked effect of gravity on quantum systems could be messing up quantum experiments. If confirmed, it suggests that some quantum studies may be impossible to perform on Earth. No matter how hard you try, you can't be in two places at once. But if you're an electron, popping up in multiple places is a way of life. The laws of quantum mechanics tell us that subatomic particles exist in this superposition of states until they are measured and found to be in just one - when their wave function collapses.
