"""Implement the multi-controlled X gate using recursion.
Using a single ancilla qubit, the multi-controlled X gate is recursively split onto
four sub-registers. This is done until we reach the 3- or 4-controlled X gate since
for these we have a concrete implementation that do not require ancillas.
Using a single clean ancilla qubit, the multi-controlled X gate is split into
four sub-registers, each one of them uses the V-chain method.
The method is based on Lemma 9 of [2], first shown in Lemma 7.3 of [1].
