MCXGate¶
- class MCXGate(num_ctrl_qubits, label=None, ctrl_state=None, _name='mcx')[소스]¶
기반 클래스:
qiskit.circuit.controlledgate.ControlledGate
The general, multi-controlled X gate.
Create new MCX gate.
Methods Defined Here
Return a multi-controlled-X gate with more control lines.
Get the number of required ancilla qubits without instantiating the class.
Invert this gate.
Attributes
- ctrl_state¶
Return the control state of the gate as a decimal integer.
- 반환 형식
int
- decompositions¶
Get the decompositions of the instruction from the SessionEquivalenceLibrary.
- definition¶
Return definition in terms of other basic gates. If the gate has open controls, as determined from self.ctrl_state, the returned definition is conjugated with X without changing the internal _definition.
- 반환 형식
List
- duration¶
Get the duration.
- label¶
Return instruction label
- 반환 형식
str
- name¶
Get name of gate. If the gate has open controls the gate name will become:
<original_name_o<ctrl_state>
where <original_name> is the gate name for the default case of closed control qubits and <ctrl_state> is the integer value of the control state for the gate.
- 반환 형식
str
- num_ancilla_qubits¶
The number of ancilla qubits.
- num_clbits¶
Return the number of clbits.
- num_ctrl_qubits¶
Get number of control qubits.
- 반환
The number of control qubits for the gate.
- 반환 형식
int
- num_qubits¶
Return the number of qubits.
- params¶
Get parameters from base_gate.
- 반환
List of gate parameters.
- 반환 형식
list
- 예외 발생
CircuitError – Controlled gate does not define a base gate
- unit¶
Get the time unit of duration.
