Coherence Arcana is a strategy–memory puzzle set in the mysterious realm of quantum circuits. As Player, your task is simple but perilous — recreate a fleeting quantum circuit before decoherence consumes it.
You’ll glimpse a quantum circuit for a few seconds. Then, using draggable circuit cards, you must rebuild it from memory on the game board. Each drag or drop increases your Decoherence Meter — fill it, and the circuit collapses.
As you build, the Decoherence Meter rises with each action. If it fills up, your circuit collapses and you’ll have to reset. Use your limited Artifact Cards to undo mistakes or stabilize the system, but remember — every artifact use comes at a price.

-
Observe: At the start of each round, you’ll briefly see a completed quantum circuit.
-
Recreate: Use drag-and-drop controls to rebuild the circuit on the board.
-
Manage Decoherence: Each move increases the Decoherence Meter. If it reaches the top, you lose coherence and must reset.
-
Use Artifacts Wisely: Artifact Cards can:
- Stabilizer Card: Remove a wrongly placed card from the board.
- Noise Filter: Discard unnecessary cards from your hand.
- Coherent Qubit: Decrease the Decoherence Meter’s progress.
Each artifact use costs 10 points.
-
Measure: Once your circuit is ready, press Measure to finalize it and calculate your score.
- Level 1: Bell State.
- Level 2: Swap 2 Qubits using CNOT Gate.
- Level 3: 3 Qubit GHZ state.
- Level 4: Quantum circuit simulating Superdense Coding.
| Action | Points |
|---|---|
| ✅ Correct circuit measured | 100 pts |
| ❌ Wrong circuit measured | 0 pts |
| 🔄 Extra moves (beyond minimum) | –5 pts each |
| 🪄 Artifact used | –10 pts each |
| 🃏 Non-discarded cards in hand | –5 pts each |
- Memory & Precision: Quickly recall and rebuild quantum circuits.
- Strategic Planning: Balance your actions against decoherence buildup.
- Risk vs Reward: Use artifacts to recover from mistakes, but at a cost.
