QuantumCircuit.reverse_ops()[source]¶

Reverse the circuit by reversing the order of instructions.

This is done by recursively reversing all instructions. It does not invert (adjoint) any gate.

Examples

input:

     ┌───┐
q_0: ┤ H ├─────■──────
     └───┘┌────┴─────┐
q_1: ─────┤ RX(1.57) ├
          └──────────┘

output:

                 ┌───┐
q_0: ─────■──────┤ H ├
     ┌────┴─────┐└───┘
q_1: ┤ RX(1.57) ├─────
     └──────────┘
