What are peoples current estimated years for when QC will... a) Break some of today's modern yet non-PQC cryptosystems? and/or b) Give major speedups or scaling to some other realworld applications?

Use RFC 2549[1] with good old OTPs and case can be closed. :-) [1] Should be updated IMHO for cheap and littel toy drones, if Cypherpunks (in case they would still exist) write routing software for that, so that an operator is not needed, when sending a letter from one home to another, in a city. :-) Regards and Good Night, Stefan

Units are already available. Regards Stefan

yes, exactly 10 years from today.
b) Quantum Supremacy will be archived by non-US/Canadian companies, as understood, operating at room temperature and lower prices. Units are already available.
so 'quantum supremacy' has been achieved....?

I seem to recall that cryptosystems based on multi-dimensional lattices are thought to be quantum-resistant. https://en.wikipedia.org/wiki/Lattice-based_cryptography?wprov=sfla1
From that: "Lattice-based cryptography is the generic term for constructions of cryptographic primitives that involve lattices, either in the construction itself or in the security proof. Lattice-based constructions are currently important candidates for post-quantum cryptography. Unlike more widely used and known public-key schemes such as the RSA, Diffie-Hellman or elliptic-curve cryptosystems, which could, theoretically, be easily attacked by a quantum computer, some lattice-based constructions appear to be resistant to attack by both classical and quantum computers. Furthermore, many lattice-based constructions are considered to be secure under the assumption that certain well-studied computational lattice problems cannot be solved efficiently."(End of quote) An RSA-type system depends on the difficulty of factoring a huge composite number, but I think that involves only one 'degree of freedom'. That is, as your guess for one factor goes up, the other goes down. However, finding distances in a large-dimensional lattice might involve as many degrees of freedom as dimensions, or maybe (dimensions minus 1). Perhaps this is what would defeat quantum calculations.

I seem to recall that cryptosystems based on multi-dimensional lattices are thought to be quantum-resistant. As understood, yes, and that was the reason why NIST run a competition and I think the winners fromround 3 are already announced. But the problem, IMHO, is all the collected encrypted data from theInternet, obtained by third parties.RegardsStefan
