Schrödinger's cat could be saved, say scientists

New research casts doubt on idea that a quantum jump is instant and unpredictable

Schridinger's cat might not only be dead or alive, but also brought back from the brink, according to scientists who said they have discovered a warning sign for quantum transitions once thought to be instantaneous and unpredictable.

The upshot is that the fate of Schridinger's cat can not only be predicted shortly in advance but even reversed once under way, the scientists said.
