Even “big” objects can be quantum TEK IMAGE/SCIENCE PHOTO LIBRARY
The quantum world keeps getting bigger. An experiment on crystals made from 10 billion atoms proves that even relatively large objects follow the weird rules of quantum mechanics.
One such rule is entanglement: the properties of two particles can聽be linked together so that measuring the state of one determines the measured state of the other in聽what Einstein called 鈥渟pooky action at a distance鈥.
A standard test for entanglement is Bell鈥檚 inequality, which sets a limit on how often two particles can end up in the same state…
