Nuclear N-body calculation using DWave quantum annealer.

NuclearNBody

Nuclear N-body calculation using DWave quantum annealer.

Requires:

dimod
dwave-system
dwave-neal
dwave_networkx
numpy
pyqubo
minorminer
networkx

To run test example:

./nbody.py -s n_spin_orbitals -f n_fermions -r num_reads -m max_evals

Change h and V in make_hamiltonian() according to the problem.

Reverse_anealing.py creates a BQM and a graph to represent it. This code requires an initial state and then outputs a BQM where all possible single electron transformations have the lowest energy. Read the comments for more details. To run, simply change varriable state_i with desired initial state and then run.

All_permutations_algorithm.py has extra qubits to represent the various initial states. This has a longer computation time but it allows for all permutations of the initial state.
