I think there could be three files: one about states (`get_ground_state`, `jw_configuration_state`, etc.) one about operations (`expectation`, `variance`, etc.), and one about restricting to subspaces (`jw_get_number_indices`, etc.). Perhaps it deserves...
I don't think QuadraticHamiltonian should depend on Givens rotations. I think the only essential method is `diagonalizing_bogoliubov_transform`. This would be a breaking change.
A lot of the code has stuff like `if abs(x) > EQ_TOLERANCE`. Is there a reason we don't do things the normal way, i.e., `if not numpy.isclose(x, 0)`? This would...
Plane waves are periodic basis functions. If one tries to use them to simulate systems of reduced periodicity (i.e. periodic in two-dimensions like graphene, one-dimension like a polymer, or zero-dimensions...
Hello OpenFermion developers I need the method (can contribute code) for generation of initial amplitudes for UCCSD from MP2 amplitudes as formula is well known. I do not quite understand...
Pull request #221 starts a comprehensive list of features which we will merge once completed (help on that welcome, especially if making additions which explain your contribution). This should help...
@TariniHardikar @kanavsetia @hsim13372 @jarrodmcc Now that we have the alpha version of our cloud library up and running (thanks again to @Spaceenter who did a lot of work on this)...
[arXiv:1502.04698](https://arxiv.org/abs/1502.04698) describes a method for "folding" correlations from Hamiltonians in larger basis sets into Hamiltonians in smaller basis sets. Thus, this is a method for obtaining minimal basis sets with...
Perturbative gadgets are techniques for manipulating representations of qubit Hamiltonians which would be very useful in some contexts. They are particularly interesting in the context of quantum simulation and multiple...
Schemes such as Dynamical Mean-Field Theory (DMFT) or Density Matrix Embedding Theory (DMET), to name just two ideas from a larger family, allow one study the properties of a much...
