What it is

Most Bloch sphere explainers are flat diagrams. Guess the Qubit puts the sphere in AR so you can walk around it, inspect the axes and state vector, and watch the Ry gate and measurement collapse. It runs on real simulator and IBM Quantum jobs.

Built with

Expo SDK 57, ViroReact (procedural Bloch sphere geometry, 3D labels, native animations), and the builder's Quantum API JavaScript SDK. It is an AR port of the builder's earlier Unreal Engine game.

“A fun novel game... with some polish could be a fun game to play casually.”
