qiskit.aqua.components.variational_forms.VariationalForm

class VariationalForm

Base class for VariationalForms.

This method should initialize the module and use an exception if a component of the module is not available.

abstract __init__()

Initialize self. See help(type(self)) for accurate signature.

Methods

__init__()	Initialize self.
construct_circuit(parameters[, q])	Construct the variational form, given its parameters.
get_entangler_map(map_type, num_qubits[, offset])	returns entangler map
validate_entangler_map(entangler_map, num_qubits)	validate entangler map

Attributes

num_parameters	Number of parameters of the variational form.
num_qubits	Number of qubits of the variational form.
parameter_bounds	Parameter bounds.
preferred_init_points	Return preferred init points.
setting
support_parameterized_circuit	Whether or not the sub-class support parameterized circuit.

abstract construct_circuit(parameters, q=None)

Construct the variational form, given its parameters.

Parâmetros

• parameters (Union[List[float], ndarray]) – circuit parameters.

• q (Optional[QuantumRegister]) – Quantum Register for the circuit.

Retorna

A quantum circuit.

Tipo de retorno

QuantumCircuit

static get_entangler_map(map_type, num_qubits, offset=0)

returns entangler map

property num_parameters

Number of parameters of the variational form.

Retorna

An integer indicating the number of parameters.

Tipo de retorno

int

property num_qubits

Number of qubits of the variational form.

Retorna

An integer indicating the number of qubits.

Tipo de retorno

int

property parameter_bounds

Parameter bounds.

Retorna

A list of pairs indicating the bounds, as (lower, upper). None indicates an unbounded parameter in the corresponding direction. If None is returned, problem is fully unbounded.

Tipo de retorno

list

property preferred_init_points

Return preferred init points.

If an initial state is provided then the variational form may provide back this set of parameters which when used on the variational form should result in the overall state being that defined by the initial state

property setting

property support_parameterized_circuit

Whether or not the sub-class support parameterized circuit.

Retorna

indicate the sub-class support parameterized circuit

Tipo de retorno

boolean

static validate_entangler_map(entangler_map, num_qubits)

validate entangler map
