A sapphire Schrödinger’s cat shows that quantum effects can scale up

A sliver of a sapphire crystal close to half the mass of an eyelash has been put in a ‘cat state’: a state of quantum superposition in which its atoms move in two directions at once. This is reminiscent of Schrödinger’s cat, a thought experiment that illustrates quantum superposition by means of a feline that appears to be simultaneously dead and alive until it is observed. The sapphire cat is more than 100 trillion times the mass of the molecules previously put in cat states.

To be clear, the quantum superposition of Schrödinger's Cat is of potential states, alive or dead, one which is instantiated when it is observed.

This research, in contrast, is concerned with actual observed states, not potential unobserved states.
