Components (qiskit.aqua.components)¶
Components were designed to be swappable sub-parts of an algorithm. Different implementations
of a component type can thereby be exchanged to potentially alter the behavior and outcome of
the algorithm. For example VQE takes an
Optimizer and a
VariationalForm components. There are a
selection of both different optimizers and
variational_forms that can be chosen from according the nature of
the problem. Some optimizers use gradients, others have alternative techniques to finding a
minimum. Variational forms include heuristic ansatzes such as
RYRZ and types designed for specific problems
such as UCCSD for chemistry and ground
state energy computation.
Components may also be used in other components. For example the
UnivariateVariationalDistribution takes a
VariationalForm.
Each type of component has a base class that can be extended to provide a new implementation. For
example the base class for variational_forms is
VariationalForm. For more information refer
to the component type of interest below.
