circuit representation respectively The Hadamard gate acts on a single qubit. It maps the basic states |0⟩ and |1⟩ into exactly equal superposition. The Hadamard gate also takes a qubit in exactly-equal superposition, and transforms it into a |0⟩ or|1⟩-bit Remember operations are their own inverse!
