C3SXGate#

class qiskit.circuit.library.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

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_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.
