class CDFHamiltonian(num_orbitals, num_fragments, one_norm=None)

Bases: object

For a compressed double-factorized (CDF) Hamiltonian, stores the minimum necessary information pertaining to resource estimation.

Parameters:

• num_orbitals (int) – number of spatial orbitals

• num_fragments (int) – number of fragments in the compressed double-factorized (CDF) representation

• one_norm (float | None) – the one-norm of the Hamiltonian

Returns:

An instance of CDFHamiltonian

Return type:

CDFHamiltonian
