Blockchain with proof of quantum work

This repository includes sampled Quantum Processsing Unit (QPU) data for each of the four generally available solvers used in our Physical Review A publication (and preprint arXiv:2503.14462). Each file is named by a generally-available solver, and the statistic type (mean or variance). If hyperplanes are projected orthogonal to J the file name contains 'orthogonal-to-J'.The file contains data for 20 J-realizations (by row) and 1024 random hyperplane (by column). A witness is defined as a weighted (by hyperplane components) sum of sampling statistics, see article for details. Each element in the file is a witness mean or variance estimated from 32 independent parallelized programmings (each differing in spin-reversal transform and embedding automorphism). This data is used in the statistical analyses of Figures 5, 13, 14, 15, 16.https://github.com/dwave-examples/quantum-blockchain/releases/tag/PRA demonstrates the hashing and blockchain methods used in our Physical Review paper demonstration adapted to the latest generally available QPUs. The code also includes the methods necessary for emulating the creation and verification of quantum hashes with and without Leap access (including by use of data matching that of this repository). This codebase is sufficient to reproduce paper statstical analyses and blockchain realizations. Methods for spin-glass generation, embedding and energy-time rescaling are also included.
