Notably, this game doesn't even try to teach about entanglement (which, no surprise, is hard to keep track of in your head!). Tt deals only with a single photon passing through a network of beamsplitters and phaseshifters: a situation that has one foot in quantum physics and one foot in classical physics (the macroscopic state of a laser beam obeys exactly the same math). But the puzzles are really clever!
If you're just trying to create an educational game, why bother using the Quantum Experience? Won't it just introduce enormous errors and delays (~30 seconds per run when I tried it), complicating and obfuscating whatever you're trying to teach? Why not just make some puzzles that force people to reason about small, idealized quantum systems, along the lines of the successful example above?
