"This paper presents implementations that match and, where possible, exceed current quantum factorisation records using a VIC-20 8-bit home computer from 1981, an abacus, and a dog.

We hope that this work will inspire future efforts to match any further quantum factorisation records, should they arise."

Note that this is three attempts to match current quantum computing records, not a single attempt utilizing all three tools.
