Replication of Quantum Factorisation Records with an 8-bit Home Computer, an Abacus, and a Dog
Abstract
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: Minor revisions made to the original to correct a few typos, clarify the use of sqrt(n) for factorisation, correct an editing error in the FIPS 186 requirements, add email addresses, and add a few additional references.
