Diagonalize arbitrary Hamiltonians

[ComputationalBasis]

Hello everyone,

I am almost finishing the project im working on. One last thing i need to know is if one can diagonalize arbitrary Hamiltonians using Qadence. For instance, let us say I want to obtain the eigenvalues and eigenstates of any Hamiltonian, is it possible? I was told I can do it using QuTiP, for example.

Thanks in advance, when I finish my project I do not mind sharing it here (but it is in spanish though).

@ComputationalBasis Yes that is possible. Take your hamiltonian block, then call block_to_tensor and simply use torch.linalg.eigh or any torch function you need for this.

Thank you so much, that is exactly what I was looking for!
