RCCXGate
class RCCXGate(label=None)
Bases: qiskit.circuit.gate.Gate
The simplified Toffoli gate, also referred to as Margolus gate.
The simplified Toffoli gate implements the Toffoli gate up to relative phases. This implementation requires three CX gates which is the minimal amount possible, as shown in https://arxiv.org/abs/quant-ph/0312225. 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 dashed box of Fig. 3.
