Physicists bring human-scale object to near standstill, reaching a quantum state

To the human eye, most stationary objects appear to be just that—still, and completely at rest. Yet if we were handed a quantum lens, allowing us to see objects at the scale of individual atoms, what was an apple sitting ...
