Quantum Street Fighter

Dear Player, You are a ninja qubit balancing on precarious space-silicon which is stuck in a loop in the quantum-universe. As magnetic fields dangerously fly around you, you will have to fight for your coherence against another ninja-qubit. Your mission, should you choose to accept it, is to defeat the other ninja-qubit using quantum gates. You can flip them over with a X-gate punch, phase-flip them using a Z-gate phaser-gun or you can confuse them into a superposition by sending them a Hadamard...
