Entanglement with Pair Operators

For studying entanglement, use pair operator bases that can create correlations.

High-Precision Derivatives (Duhamel)

The Duhamel integration method provides high-precision quantum derivatives.

Third-Order Cumulants

The third cumulant \(\nabla G = \nabla \nabla \nabla \psi\) describes how the Fisher metric varies.

Optimisation on Manifolds

Constrained optimization techniques for quantum state spaces.
