Building a QFT Comparison Table for a Paper With One Shell Loop and OQFT

A paper or a design review usually wants one table: circuit size against depth and gate count, for a few register sizes and error targets. oqft stats prints all of it, one size at a time. A short shell loop turns that into a CSV file you can drop into a spreadsheet or a LaTeX table.

echo "qubits,eps,qft_depth,oqft_depth,qft_gates,oqft_gates"
for n in 64 256 1024; do
  for eps in 0.1 0.01; do
    oqft stats -n "$n" --eps "$eps" | awk -v n="$n" -v e="$eps" '
      /^Total gates/ {qg = $3}
      /^Depth/       {qd = $2}
      /^OQFT/        {gsub(",", ""); print n "," e "," qd "," $NF "," qg "," $6}'
  done
done > qft-table.csv

The awk part picks three lines out of each report: the textbook total from “Total gates”, the textbook depth from “Depth”, and both OQFT figures from the line that starts with “OQFT”. The commas inside that line are stripped so they don’t split the CSV.
