ImaginaryVariationalPrinciple¶
- class ImaginaryVariationalPrinciple(qgt, gradient)[source]¶
Bases:
qiskit.algorithms.time_evolvers.variational.variational_principles.variational_principle.VariationalPrinciple,abc.ABCAbstract class for an Imaginary Variational Principle. The imaginary variant means that we consider imaginary time dynamics.
- Parameters
qgt (
BaseQGT) – Instance of a class used to compute the GQT.gradient (
BaseEstimatorGradient) – Instance of a class used to compute the state gradient.
