RealVariationalPrinciple

class qiskit.algorithms.time_evolvers.variational.RealVariationalPrinciple(qgt, gradient)

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.
