qiskit.aqua.components.variational_forms.VariationalForm¶
-
class
VariationalForm[source]¶ Base class for VariationalForms.
This method should initialize the module and use an exception if a component of the module is not available.
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
Number of parameters of the variational form.
Number of qubits of the variational form.
Parameter bounds.
Return preferred init points.
Whether or not the sub-class support parameterized circuit.

abstract
construct_circuit(parameters, q=None)[source]¶ Construct the variational form, given its parameters.
- Parameters
parameters (
Union[List[float],ndarray]) – circuit parameters.q (
Optional[QuantumRegister]) – Quantum Register for the circuit.
- Returns
A quantum circuit.
- Return type
-
property
num_parameters¶ Number of parameters of the variational form.
- Returns
An integer indicating the number of parameters.
- Return type
int
-
property
num_qubits¶ Number of qubits of the variational form.
- Returns
An integer indicating the number of qubits.
- Return type
int
-
property
parameter_bounds¶ Parameter bounds.
- Returns
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.
- Return type
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

support_parameterized_circuit¶ Whether or not the sub-class support parameterized circuit.
- Returns
