RealVariationalPrinciple¶

class qiskit.algorithms.time_evolvers.variational.RealVariationalPrinciple(qgt, gradient)[source]¶

Bases: VariationalPrinciple, ABC

Class for a Real Variational Principle. The real variant means that we consider real 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.
