GPUniverse models quantum fields in finite dimensional Hilbert spaces with Generalised Pauli Operators (GPOs) and overlapping degrees of freedom. In addition, the package can simulate sets of qubits that are only quasi independent (i.e., the Pauli algebras of different qubits have small, but non-zero anti-commutator), which is useful for validating analytical results for holographic versions of the Weyl field.

The MapCUMBA package applies a multigrid fast iterative Jacobi algorithm for map-making in the context of CMB experiments.
