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.

パラメータ

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

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

戻り値

A quantum circuit.

戻り値の型

QuantumCircuit

static get_entangler_map(map_type, num_qubits, offset=0)

returns entangler map

property num_parameters

Number of parameters of the variational form.

戻り値

An integer indicating the number of parameters.

戻り値の型

int

property num_qubits

Number of qubits of the variational form.

戻り値

An integer indicating the number of qubits.

戻り値の型

int

property parameter_bounds

Parameter bounds.

戻り値

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.

戻り値の型

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.

戻り値

indicate the sub-class support parameterized circuit

戻り値の型

boolean

static validate_entangler_map(entangler_map, num_qubits)

validate entangler map
