RealVariationalPrinciple

class RealVariationalPrinciple(qgt, gradient)

Bases: qiskit.algorithms.time_evolvers.variational.variational_principles.variational_principle.VariationalPrinciple, abc.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.
