Gate The Hadamard gate (H-gate) is a fundamental quantum gate. It allows us to move away from the poles of the Bloch sphere and create a superposition of |0⟩ and |1⟩. It has the matrix: We can see that this performs the transformations below: H|0⟩=|+⟩ H|1⟩=|−⟩ This can be thought of as transforming
