That would be awesome. Do you have a reference? As pertains to the whole of asymmetric cryptography, I believe there are not a variety of post quantum schemes, there is only one*: lattice-based cryptography. (Which scares me, because it is not all that different from the others.)
(* Actually, in contexts where time can be used for asymmetry, as in TESLA, we can then use hash functions to create something like asymmetric signatures as well. But the functional context has to be compatible with delayed verification.) (But I do not mean to focus exclusively on Schor's algorithm, the history of even pre-quantum cryptanalysis shows that primitives tend to have finite lifespan. Redundancy of any sort of good, even when not focused specifically on quantum risks.)
