Compressible tight-binding Hamiltonians on N=2^L sites map to L-pseudospin MPOs and can be solved at billion-site scale with TensorBinding.jl without explicit matrix storage.
Conservation laws in quantum circuits and Hamiltonians replace logarithmic coherence saturation with slow hydrodynamic relaxation globally and produce algebraic peak-time growth locally, unlike ergodic cases.
