C3SXGate¶
- class C3SXGate(label=None, ctrl_state=None)[소스]¶
기반 클래스:
ControlledGate
The 3-qubit controlled sqrt-X gate.
This implementation is based on Page 17 of [1].
참조
[1] Barenco et al., 1995. https://arxiv.org/pdf/quant-ph/9503016.pdf
Create a new 3-qubit controlled sqrt-X gate.
- 매개변수
label (str or None) – An optional label for the gate [Default: None]
ctrl_state (int or str or None) – control state expressed as integer, string (e.g. 〈110〉), or None. If None, use all 1s.
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_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.
