This would enable the creation of quantum-correlated spin states over macroscopic distance, an as yet unexplored version of Schrödinger's cat.

He imagined a box containing a radioactive atom, a vial of poison and a cat. Governed by quantum rules, the radioactive atom can either decay or not at any given moment. There’s no telling when ...

"No one has ever seen an actual cat in a state of being both dead and alive at the same time, but people use the Schrödinger's cat metaphor to describe a superposition of quantum states that ...

Physicists at the University of New South Wales (UNSW) are the first to succeed in creating and manipulating quantum superpositions of a single, large nuclear spin. The superposition involves spin ...
