qiskit.circuit.QuantumCircuit.inverse¶
-
QuantumCircuit.inverse()[source]¶ Invert (take adjoint of) this circuit.
This is done by recursively inverting all gates.
- Returns
the inverted circuit
- Return type
- Raises
CircuitError – if the circuit cannot be inverted.
Examples
- input:
┌───┐
- q_0: ┤ H ├─────■──────
└───┘┌────┴─────┐
- q_1: ─────┤ RX(1.57) ├
└──────────┘
- output:
┌───┐
- q_0: ──────■──────┤ H ├
┌─────┴─────┐└───┘
- q_1: ┤ RX(-1.57) ├─────
└───────────┘
