C3SXGate

class C3SXGate(label=None, ctrl_state=None)[fuente]

Bases: ControlledGate

The 3-qubit controlled sqrt-X gate.

This implementation is based on Page 17 of [1].

Referencias

[1] Barenco et al., 1995. https://arxiv.org/pdf/quant-ph/9503016.pdf

Create a new 3-qubit controlled sqrt-X gate.

Parámetros
  • 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.

Tipo del valor devuelto

List[Clbit]

ctrl_state

Return the control state of the gate as a decimal integer.

Tipo del valor devuelto

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.

Tipo del valor devuelto

List

duration

Get the duration.

label

Return instruction label

Tipo del valor devuelto

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.

Tipo del valor devuelto

str

num_clbits

Return the number of clbits.

num_ctrl_qubits

Get number of control qubits.

Devuelve

The number of control qubits for the gate.

Tipo del valor devuelto

int

num_qubits

Return the number of qubits.

params

Get parameters from base_gate.

Devuelve

List of gate parameters.

Tipo del valor devuelto

list

Muestra

CircuitError – Controlled gate does not define a base gate

unit

Get the time unit of duration.
