Independent replication invited — derived onset thresholds for the Petz recovery bound on a qubit witness (five preregistered studies)
We are a small research program that publishes preregistered computational studies. We are writing to invite independent replication of five related results about the Petz recovery map.
Each study first derived — analytically, before any computation — a specific number describing where the ordinary Petz map's recovery bound holds and where it fails on a fixed qubit witness, and then tested that number in a frozen, preregistered simulation campaign. All five tests reproduced the derived values. The numbers are concrete enough to be checked by anyone:
