QuantumBob puts real quantum physics in your hands. Compete against Alice, an AI that uses actual entanglement data from IBM's quantum processor, by guessing measurement outcomes. Can you beat the quantum advantage? PLAY REAL QUANTUM DATA Every round, a real quantum computer has already measured an entangled particle pair. You guess the result — 0 or 1. Alice reads her linked particle and makes the same prediction. The quantum correlations give her an edge that no classical strategy can match. THE QUANTUM ADVANTAGE Without quantum physics, the best any strategy can achieve is 75% accuracy. But Alice's entangled particles push her to about 85%. That 10% gap is physically impossible without quantum mechanics. You'll see it happen in real time as you play. FEATURES - Real quantum measurement data from IBM's Marrakesh quantum processor - Compete against Alice's quantum-powered AI in 10-round ranked games - Challenge friends with local pass-and-play multiplayer - Learn quantum concepts as you play with contextual tips - Track perfect rounds, win average, and Alice's accuracy over time - Explore interactive lessons on entanglement, Bell's theorem, and the Tsirelson bound - Compare real quantum data against classical fakes side by side - Run built-in statistical proof tests that verify the quantum advantage - Game Center leaderboards to compete globally NO PHYSICS DEGREE REQUIRED QuantumBob starts from zero. The interactive tutorial walks you through everything — from "what is 0 and 1?" to "why can't I beat 75%?" to "what makes quantum special?" You'll understand entanglement through playing, not studying. THE SCIENCE BEHIND THE GAME QuantumBob is built on the CHSH Bell experiment, one of the most important experiments in quantum physics. In 2022, the Nobel Prize in Physics was awarded for work proving that quantum entanglement violates Bell inequalities — exactly what you experience every time you play. All quantum data comes from real IBM quantum hardware. No simulations, no random number generators — actual measurements of entangled qubit pairs. Download QuantumBob and discover why quantum physics breaks the rules.
