Initial States (
Initial states are a fixed quantum state. These can be used, for example, to define a starting
variational_forms, such as when used with
VQE, or to define a starting state for the evolution
in algorithms such as
If you have a specific quantum circuit you would like to use as an initial state, and do not
want to make a new class derived from
InitialState to use it, this can be especially so
if the circuit is fixed, then see
Custom which allows it to be used as an
InitialState for algorithms and components that expect this as a type.
Initial State Base Class¶
