Build Games with Real Quantum Mechanics
Superposition, entanglement, and interference as simple game properties. Not random numbers. Real quantum mechanics running in your game loop.
A new kind of emergent gameplay
Quantum mechanics is a new playground for game designers. Superposition, entanglement, and interference are real physical laws tied to the fundamental fabric of the universe. The emergent gameplay they produce is unlike anything available from classical systems.
Structure, Not Randomness
Superposition isn't "maybe." It's all states at once, with mathematical relationships intact. Interference creates patterns. Entanglement creates correlations. The resulting behavior feels designed, but nobody wrote it.
Players Discover, Designers Don't Dictate
When quantum states entangle, they create correlations across your entire game. Players find strategies you never planned. Speedrunners exploit quantum effects you didn't know were there.
Proven in Production
Three shipping games. A Caltech IQIM × LCAD game jam where student teams built playable quantum games in one week. The API is backend-agnostic: the same game code runs on simulation today and on quantum hardware without changes. We've done it.
Shipping games. Real quantum mechanics.
Every game below runs real quantum simulation. Superposition, entanglement, and interference drive the core gameplay, not the art direction.
Quantris
Tetris meets quantum mechanics. Blocks exist in superposition until measured. Entangle pieces across the tower. Clear lines by collapsing reality.
Play QuantrisQuantum Chess
Chess with quantum moves. Pieces exist in superposition across multiple squares. Entangle pieces, split moves, and use interference to outmaneuver your opponent.
View on SteamPonq
Quantum pong with entangled balls. Balls split and recombine through quantum zones. Phase affects trajectory. Measure to score.
Play PonqBloch Invaders
Space invaders on the Bloch sphere. Damage scales with quantum state overlap. Enemies decohere, entangle, and implement the quantum Zeno effect.
In DevelopmentIn 2024, we partnered with Caltech's IQIM and LCAD to run a quantum game jam. Student teams built playable quantum games in one week using Quantum Forge.
New opportunities for emergent gameplay
Probability spreads from the center tile. Click outer hexes to add barriers. Classical probability just redistributes evenly. Quantum probability creates asymmetric pockets through destructive interference. Those pockets are the emergent gameplay.
Classical probability mixes uniformly and always settles to an even split. Quantum applies a unitary operator that preserves phase, so it never settles. Barriers reshape the interference pattern instead of just redistributing probability.
Where we are
Classical computing took decades to go from room-sized machines to the games we play today. Quantum computing is on the same exponential curve. We're in the early chapters.

Three steps to quantum gameplay
Define quantum properties
Attach quantum state to any game object. A coin flip is dimension 2, a die is dimension 6, a hex tile is dimension 6. Each property becomes a qudit in the simulation.
Let players shape the quantum state
Give players tools that influence state evolution: actions, abilities, or choices that apply quantum operations. Players don't need to know the math. They discover that their choices create interference patterns, correlations, and strategies that feel new.
Measure to resolve
You decide when the quantum state collapses into a definite outcome. Everything the player did to shape the state influences what they get. Measurement is the payoff, not the gameplay.
// 1. Define: a door with 3 possible destinations const door = quantum.acquire({ dimension: 3 }); quantum.hadamard(door); // all three destinations at once // 2. Player shapes the state: using a crystal rotates probability function onUseCrystal(targetDest: number) { quantum.phase(door, targetDest, Math.PI / 4); } // Player can also entangle the door with a key const key = quantum.acquire({ dimension: 3 }); quantum.iSwap(door, key, 0.5); // now correlated // 3. Resolve: player steps through, state collapses const destination = quantum.measure(door); // The key collapses too — wherever it is, it matches
