RC3XGate

class RC3XGate(label=None)

The simplified 3-controlled Toffoli gate.

The simplified Toffoli gate implements the Toffoli gate up to relative phases. Note, that the simplified Toffoli is not equivalent to the Toffoli. But can be used in places where the Toffoli gate is uncomputed again.

This concrete implementation is from https://arxiv.org/abs/1508.03273, the complete circuit of Fig. 4.

Create a new RC3X gate.
