U3Gate
class U3Gate(theta, phi, lam, label=None)
Bases: qiskit.circuit.gate.Gate
Generic single-qubit rotation gate with 3 Euler angles.
Circuit symbol:
┌───────────┐
q_0: ┤ U3(ϴ,φ,λ) ├
└───────────┘
Matrix Representation:
The matrix representation shown here differs from the OpenQASM 2.0 specification by a global phase of .
Examples:
Create new U3 gate.
Methods Defined Here
control
U3Gate.control(num_ctrl_qubits=1, label=None, ctrl_state=None)
Return a (multi-)controlled-U3 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
U3Gate.inverse()
Return inverted U3 gate.
