Quantum mazes

Welcome to the quantum maze! Where is the maze I hear you ask?  Well, still in its many quantum states, awaiting your direction. Start exploring and the maze will begin to "collapse" around you, with walls materialising in positions dictated by your chosen route.  Can you successfully build and navigate the maze - both at the same time?
