HGate
HGate(label=None)
Bases: qiskit.circuit.gate.Gate
Single-qubit Hadamard gate.
This gate is a pi rotation about the X+Z axis, and has the effect of changing computation basis from to and vice-versa.
Circuit symbol:
┌───┐
q_0: ┤ H ├
└───┘Matrix Representation:
Create new H gate.
Methods Defined Here
control
HGate.control(num_ctrl_qubits=1, label=None, ctrl_state=None)
Return a (multi-)controlled-H gate.
One control qubit returns a CH gate.
Parameters
- num_ctrl_qubits (int) – number of control qubits.
- label (str or None) – An optional label for the gate [Default: None]
- ctrl_state (int or str or None) – control state expressed as integer, string (e.g. ‘110’), or None. If None, use all 1s.
Returns
controlled version of this gate.
Return type
inverse
HGate.inverse()
Return inverted H gate (itself).
