comment Can a symmetry-preserving unitary transformation that goes from a trivial SPT to a non-trivial SPT be local?
Thanks for Everett You's comment which is very clear. I modified my answer to make it more clear.

comment advantages and disadvantages of using topological quantum computation to study grand-unified SO(10) supersymmetric standard model
I do not know any refs in this direction. Also, it seems that SO(10) supersymmetric model is not the standard model.

comment Topological Charge. What is it Physically?
topological quasiparticle ie "domain-wall" in symmetry breaking phase are not stable. If we break the symmetry they will confine.

comment Can spin-1/2 emerge as a property of quasiparticles if original description of the system was without spin?
Thank you for fixing the answer!
