Fun with Quantum

Quantum computing taught through games: Jupyter notebooks, written with Qiskit, in which superposition, interference and entanglement are the tricks that win the game. Play first, then pull back the curtain and see the circuit.

More games, and the family of projects around them: fun-with-quantum.org.

▶ Open starts a free Jupyter session on mybinder.org through QuBins, with Qiskit preinstalled — no install, no account. Starting it can take a few minutes. Games 1–7 open as slideshows (how to use them); game 8 opens as a regular notebook. Binder builds this repository's own environment instead, which can take longer. View shows the notebook on GitHub without running it.

1. Quantum Coin Game

A quantum coin game that illustrates the power of quantum superposition and interference — two players take turns turning a hidden coin or leaving it as it is, and the player who may also use a Hadamard gate can win every time. Implemented by Jan-R. Lahmann using Qiskit, binder and RISE.

Play it right in your browser — no Jupyter, in seven languages: fun-with-quantum.org/play/quantum-coin-game.

Inspired by the TED talk of Shohini Ghose "Quantum computing explained in 10 minutes". The math behind the game: these charts.

2. GHZ Game

A quantum game that illustrates the power of quantum entanglement: three players answer questions about colors and shapes without talking. No classical team wins every round; sharing three entangled qubits in a GHZ state, they always do. Implemented by Isabell Heider using Qiskit.
