Re: Is 2029 a Realistic Date?
@ParlezVousFranglais: Thanks. I found the https://algassert.com/post/2500 article to be fascinating. My take aways.
1. 15 happens to be an exceptionally easy number for QCs to factor.
2. The claimed factoring of 21 is much, much harder than factoring 15 and could only be done because they already knew the answer.
3. If you're looking to make a financial killing, Penney Canadian Mining Stocks are likely a better bet than betting on a QC company.
I recall reading and much enjoying Replication of Quantum Factorisation Records with an 8-bit Home Computer, an Abacus, and a Dog some time ago. I think I'll go check some of the other links in the article and see if there are any I can understand.
