MCXGate¶

class MCXGate(num_ctrl_qubits=None, label=None, ctrl_state=None)[소스]¶

기반 클래스: ControlledGate

The general, multi-controlled X gate.

Can be applied to a QuantumCircuit with the mcx() method.

Create new MCX gate.

Methods Defined Here

`control`	Return a multi-controlled-X gate with more control lines.
`get_num_ancilla_qubits`	Get the number of required ancilla qubits without instantiating the class.
`inverse`	Invert this gate.

Attributes

condition_bits¶: Get Clbits in condition.

ctrl_state¶: Return the control state of the gate as a decimal integer.

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.

duration¶: Get the duration.

label¶: Return instruction label

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.

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.
