How many moves does it take to solve a Rubik’s cube if it is quantum?

A quantum Rubik’s cube would be infinitely more complex than the traditional puzzle, but mathematical modelling shows it wouldn’t be unsolvable.
In the summer of 2022, Noah Lordi and Maedée Trank-Greene at the University of Colorado Boulder and their colleagues made a bet: how many possible states would a quantum Rubik’s cube have? To even make their guesses, they first had to define what a quantum Rubik’s cube would entail.
