qiskit.circuit.QuantumCircuit.reverse_bits

QuantumCircuit.reverse_bits()[fuente]

Return a circuit with the opposite order of wires.

The circuit is «vertically» flipped. If a circuit is defined over multiple registers, the resulting circuit will have the same registers but with their order flipped.

This method is useful for converting a circuit written in little-endian convention to the big-endian equivalent, and vice versa.

Devuelve
