- classmethod cnx(circ, q, aux, q_num)¶
Function cnz : using the basic Toffoli gates and CZ gate to implement cc..cx gate,which includes n control gates.
- Parameters
circ – quantum circuit
q – qubits list. The last is target qubits
aux – auxiliary qubits
q_num – the number of qubits in q.
- classmethod cnz(circ, q, aux, q_num)¶
Function cnz : using the basic Toffoli gates and CZ gate to implement cc..cz gate,which includes n control gates.
- Parameters
circ – quantum circuit
q – qubits list. The last is target qubits

q_num – the number of qubits in q.
- classmethod neg_weight_gate(circ, qubits, aux, state)¶
Function neg_weight_gate : adding NOT(X) gate before the qubits associated with 0 state. For example, if we want to flip the sign of |1101>, we add X gate for q2 beforethe cccz gate, as follows.
- Parameters
circ – quantum circuit
qubits – the register of input qubits
aux – auxiliary qubits
state – a string that represents the state of the qubits,such as ‘1101’
