Result data for Exploring ab initio machine synthesis of quantum circuits

This repository collects the data produced for the paper Exploring ab initio machine synthesis of quantum circuits (arXiv:2206.11245). The filenames are in the format

<target>_<n>qb_<method>_<gateset>.json

where target is the unitary we are trying to produce, n is the number of qubits of the target, method is either tabu for tabu search, or rand for random search, and gateset is either all-controlled for controlled rotations with all-to-all connectivity, nn-controlled for controlled rotations with only nearest-neighbour connectivity on a linear chain, or swap for local rotations plus a parametrised SWAP gate between neighbouring qubits in a linear chain. There may be a self-explanatory comment in the filename after the gate set as well.

The structure of the JSON files is quite straightforward. There are some general parameters reiterating information from the filename, as well as the maximum number of iterations used. The runs array contains all attempts at synthesising a circuit, each having the final energy of the attempt, the number of iterations, the time as measured by the code itself, as well as the walltime calculated from SLURM logfiles (these should be roughly identical for completed runs that exited normally), whether the run finished normally or was terminated by a timeout, the number n_gates of gates in the final circuit, what the energy was througout each iteration (energy_progression), as well as the final circuit the run produced, where each gate has target qubits and a rotation angle.
