X-Gate The X-gate is represented by the Pauli-X matrix, which is: To see the effect this gate has on qubit, we simply multiply the qubit’s statevector by the gate. We can see that the X-gate switches the amplitudes of the state |0⟩ and |1⟩. Remember that the states |0⟩ and |1⟩ can be represented as
