ImaginaryVariationalPrinciple#

class ImaginaryVariationalPrinciple(qgt, gradient)[source]#

Bases: VariationalPrinciple, ABC

Abstract 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.
