Again, wow! "behind my back" means you denigrated my work in a public forum without apprising me. For all you knew, or cared, I'd never have seen this and the harm you inflicted would have been done. What if I went around in public forums and said, "Hey there's this crackpot out there, Ron Garret, check him out on your bogometer"? Most of us learn at a young age not to disparage people behind their back. Apparently you didn't learn that. You introduced the term "quantum supremacy" to our discussion. I don't usually think in such hype-y / marketing terminology, but I assented because I take it to be synonymous with there being a classical realization of quantum superposition. There is. Sparsey is an example. But you haven't taken the time, again by your own admission, to study or understand that. For the (apparently hundreds, based on hits on my website) of others watching this thread, my short 2012 paper, "Quantum Computation via Sparse Distributed Representation", clearly describes how the probabilities of multiple states can simultaneously, physically be active, in superposition if those states are represented as sparse distributed representations (SDRs). And, contrary Ron Garret's claim, my 2017 paper, "A Radically New Theory of how the Brain Represents and Computes with Probabilities", provides empirical evidence that the probabilities of all states (hypotheses) represented (stored) in an SDR coding field are updated (in a way that is semantically consistent with the learned dynamics of the input space) with a number of steps that remains constant as the number of stored states increases. That capability is minimally necessary for any quantum algorithm. I don't know of any other model that has shown this ability. I think the mental block that has existed thus far in quantum computing (QC), and in quantum theory (QT) more generally, is that theorists have been thinking in terms of the probability amplitudes of states as being represented in localist fashion A localist representation is one in which any single entity is represented by a single representational unit and that unit represents only that entity. Any localist simulation of QC on a classical machine will require exponential memory. But, an SDR coding space has a storage capacity of combinatorial order. This opens the possibility that an exponential order number of states can be represented in the polynomial number of units comprising the SDR coding field.

> you denigrated my work in a public forum without apprising me I'm sorry, I didn't realize I was under any obligation to apprise you. You certainly never asked me to, and if there's some kind of universal social obligation that applies here that's news to me. (BTW, did it even occur to you that the reason I did this is not because I'm a coward or a drunkard, but simply because I might be clueless?) > the harm you inflicted would have been done What harm could I possibly inflict? I have no influence in the quantum computing community. I've never published anything in that field, and I've been retired from research in general for nearly 20 years. No one who matters has any reason to pay attention to what I say. The only way my critique could possibly harm you is if it has merit. (Does it?) > What if I went around in public forums and said, "Hey there's this crackpot out there, Ron Garret, check him out on your bogometer"? You mean like when Lubos Motl called me a "category 5 loon"? https://motls.blogspot.com/2012/10/evading-quantum-mechanics-again.html https://motls.blogspot.com/2012/10/evading-quantum-mechanics... I was actually flattered that someone of Lubos's stature would take notice of my work and put forth the effort to criticize it. I think it said more about Lubos than it did about me that he chose to lob an ad-hominem at me, but whatever, it's a win-win for me: either Lubos is right, and I learn something, or he's wrong, and I get to be smug about having taught him something. :-) It's certainly not worth getting upset over. > You introduced the term "quantum supremacy" to our discussion. That's true, but I introduced it in the context of a question: are you claiming that you have achieved quantum supremacy in a classical computer?

(In retrospect, I guess the fact that you had to look Shor's algorithm up on Wikipedia should have been a clue.) So... now that you do know it, I am going to ask you again: are you claiming to have achieved quantum supremacy on a classical computer?

The math has been stated,the resources to understand the algorithm are all there and not particularly hard to understand if you take the time. If you have questions on implementing the algorithm on your own you can ask. Otherwise there will eventually be public code available for people to see themselves and you can just wait for it. Have a nice night.

    I understand the math. What I don't understand (yet) is what the benefit is supposed to be. Why should I care about the math? What can I do with an SDR that I cannot do equally well some other way? When Gerard originally approached me, he gave me what was essentially answer to that question that I interpreted as claiming that he had achieved quantum supremacy on a classical computer. When I asked him to confirm this, he did. But the problem is, it turns out that Gerard didn't know what quantum supremacy was. He thought it was "hype-y / marketing terminology". It isn't. It's a technical term with a precise meaning [2]. So this whole mess is, AFAICT, just a misunderstanding.
