The imaginary feline known as Schrödinger’s cat, which is both alive and dead (or neither) until beheld, is the best-known representation of the real-life phenomenon known as superposition. Now, for the first time, scientists have demonstrated superposition over a macroscopic scale of about a half-yard (0.54 meters). This finding reveals that superposition is possible at the distances and timescales of everyday life, researchers said.
