The experiments require macroscopic quantum state preparation and quantum erasure by a hypothetical quantum computer which is currently outside experimental possibility.
In water-immiscible solvents, oil-in-water emulsions are not stable as the oil droplets coalesce until complete phase separation is achieved at macroscopic levels.
Random number generators can also be built from random macroscopic processes, using devices such as coin flipping, dice, roulette wheels and lottery machines.
Since the binasuan inverts the arm through rotation, it is sometimes given as a macroscopic, physical demonstration of the rotation properties of a spin- spinor.
