What you (player 1) are trying to do is to get the qubit to collapse into the \"0\" state. Your opponent (player 2) will \
trying to do the same, but they will be trying to get the qubit to collapse into the \"1\" state. \
You are both able to apply the [X], [Y], [Z], [Rx], [Ry], [Rz], [CNOT], [SWAP], and onto the circuit \
to manipulate the qubits. You each will have 3 opportunies to apply the gates before the game measures the qubits. Good luck!")
