QuantumBob
Can you outsmart quantum physics?
QuantumBob is a quantum physics game where you guess the outcomes of real quantum measurements and compete against Alice, an AI opponent powered by actual entanglement data from IBM's quantum processor.
Every round, a quantum computer has already measured an entangled particle. You guess the result: 0 or 1. Alice uses her linked particle to make the same prediction. The quantum correlations give her an edge that no classical strategy can match.
How It Works
- Real quantum data from IBM's Marrakesh quantum processor, not simulations
- Play 10 rounds per game and try to beat Alice's quantum-powered predictions
- Learn as you play with contextual tips about entanglement, the classical limit, and Bell's theorem
- Track your stats with perfect rounds, win average, and Alice's accuracy over time
- Challenge friends with local multiplayer pass-and-play mode
- Explore the proof with built-in statistical tests that verify the quantum advantage is real
The Science
QuantumBob is built on the CHSH Bell experiment, one of the most important experiments in quantum physics. Without quantum entanglement, the best any strategy can achieve is 75% accuracy (the classical limit). But quantum correlations push Alice's accuracy to approximately 85%, a number called the Tsirelson bound. That gap is physically impossible without quantum physics, and you can see it happen in real time as you play.
