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-gate. As soon as the entities of the LOOP will offer you a gate, it is your task to collect it, and fire it onto the other ninja-qubit.

Player 1: Move left using the left arrow (<), right using the right arrow (>) and jump using the up arrow (^). Shoot the collected gate onto the other ninja-qubit using the down arrow (v).
Player 2: Move left using the Z key, right using the X key and jump using the S key. Shoot the collected gate onto the other ninja-qubit using the A key. Gravity from a nearby star will pull you downwards.

We thank you for your dedicated work towards saving the fragile coherence of the LOOP’s quantum bits.
