Quantum tic-tac-toe (2006)

Quantum tic-tac-toe

Quantum tic-tac-toe is a game that was invented by Allan Goff of Novatia Labs. It is a “quantum generalization” of tic-tac-toe in which the players’ moves are “superpositions” of plays in the classical game. The game was created as a way of introducing quantum physics without mathematics and offering a conceptual understanding of what it means to be in two places at once. The rules of quantum tic-tac-toe attempt to capture three phenomena of quantum systems: superposition, entanglement, and collapse.

Why is Quantum tic-tac-toe Popular?

Quantum tic-tac-toe is significant because it provides a fun and engaging way to learn about quantum mechanics. It is a playful learning environment for quantum mechanics that can help players understand the functioning of quantum gates in a playful way. The game is also significant because it has spawned new research and insights into abstract quantum systems.

Game Components of Quantum tic-tac-toe

A 3×3 gridX and O piecesQuantum pieces that represent qutrits (like qubits, but instead of having states 0 and 1, qutrits have states 0, 1, and 2)

Game Setup of Quantum tic-tac-toe

The game is set up like a traditional game of tic-tac-toe, with a 3×3 grid and X and O pieces. However, there are also quantum pieces that represent qutrits.

Gameplay Mechanics of Quantum tic-tac-toe

A typical game of quantum tic-tac-toe will look very much like regular tic-tac-toe until one of the players decides to make a quantum move. The squares in quantum tic-tac-toe are all fully quantum, and moves made by the players are unitary operations acting on them. The game consists of these essential elements: superposition, entanglement, and collapse.

Game Objective of Quantum tic-tac-toe

The objective of quantum tic-tac-toe is the same as traditional tic-tac-toe: to get three of your pieces in a row, either horizontally, vertically, or diagonally.
