qiskit.aqua.components.feature_maps.FeatureMap

class FeatureMap

Base class for FeatureMap.

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(x[, qr, inverse])	Construct the variational form, given its parameters.
get_entangler_map(map_type, num_qubits)	get entangle map
validate_entangler_map(entangler_map, num_qubits)	validate entangler map

Attributes

feature_dimension	returns feature dimension
num_qubits	returns number of qubits
support_parameterized_circuit	returns whether or not the sub-class support parameterized circuit

abstract construct_circuit(x, qr=None, inverse=False)

Construct the variational form, given its parameters.

Parameter

• x (numpy.ndarray[float]) – 1-D array, data

• qr (QuantumRegister) – the QuantumRegister object for the circuit, if None, generate new registers with name q.

• inverse (bool) – whether or not inverse the circuit

Rückgabe
