Code and data for "Probabilistic bits that sample quantum circuits from the Born rule"

Code and data for the manuscript "Probabilistic bits that sample quantum circuits from the Born rule" (submitted to Nature Communications). The package contains the Python model of the packet state and the Born-field sampler with the Feynman-path and Gibbs baselines, the optimized CPU samplers, the Verilog RTL of the sampling engine with feed-forward and its testbenches, the bit-exact model of the fixed-point datapath, the FPGA build scripts and implementation reports, the host software and measurement records of the ZCU104 board runs, and the aggregated post-layout results of the 28-nm design. The numbers in the manuscript and its Supplementary Information are produced by these scripts or read from these records, except the area and block-level values of the 28-nm design. Code is released under the MIT License and data under CC BY 4.0. See README.md in the archive for the folder layout and the steps to reproduce the board results.
