Quantum Game

Drag mirrors and detectors onto the board to route single photons through real quantum physics.

Quantum Game turns optics into a hands-on puzzle. Place beam splitters, mirrors, polarizers and detectors, then fire a photon and watch superposition and entanglement play out on the grid. Each level asks you to make the photon reach a detector with a target probability, and an encyclopedia explains the physics behind every component. Built with a real quantum simulation underneath, it is as educational as it is clever.

Tip: use your keyboard arrows / touch to control the game.
