    "abstract": "We demonstrate the onset of strong on-site localization in a one-dimensional\nmany-particle system. The localization is obtained by constructing, in an\nexplicit form, a bounded sequence of on-site energies that eliminates resonant\nhopping between both nearest and remote sites. This sequence leads to\nquasi-exponential decay of the single-particle transition amplitude. It also\nleads to strong localization of stationary many-particle states in a\nfinite-length chain. For an {\\it infinite} chain, we instead study the time\nduring which {\\it all} many-particle states remain strongly localized. We show\nthat, for any number of particles, this time exceeds the reciprocal frequency\nof nearest-neighbor hopping by a factor $\\sim 10^5$ already for a moderate\nbandwidth of on-site energies. The proposed energy sequence is robust with\nrespect to small errors. The formulation applies to fermions as well as\nperpetually coupled qubits. The results show viability of quantum computing\nwith time-independent qubit coupling.",
