Superposition Arcade is a mind-melting puzzle game built on an realistic simulation of quantum circuits. Your goal is simple: balls fall from the top of the screen, and you need to place pegs to bounce them into the right holes. Each row of pegs is a quantum logic gate, so your choices build up a complex quantum circuit. Gain an intuition for how all the gates work, solve levels based on real quantum circuit identities, and try to find the smallest circuits to solve real-world quantum computing problems!
How to play:
- Drag gates from the box in the lower-left to the board on the left
- Use the gates to bounce all the balls into the matching holes
- Press the Turbo button to speed up the game once you have a solution
- Mouse over a peg to see arrows showing where it sends the balls

To build the project from source, do the following:
- Install Unity 2022.3.10f1
- Clone this repository
- Open the project in Unity
- Play the game in the Unity Editor, or follow the guide here to export a build for web
Superposition Arcade is built in the Unity game engine. Superposition Arcade does not use any external code libraries.
The quantum circuits in Superposition Arcade are simulated with a simple custom quantum simulator, mostly implemented in the Assets/Scripts/QData.cs file. They include a variety of unitary gates, as well as some non-unitary gates, including measurement and noise. The game currently does not support changing the circuit based on the result of measurements, as this would be complex to build into the UI.
All the code in this repository is my original work, as are the UI, background, and VFX.
