    "abstract": "We introduce a general scheme to realize perfect quantum state reconstruction\nand storage in systems of interacting qubits. This novel approach is based on\nthe idea of controlling the residual interactions by suitable external controls\nthat, acting on the inter-qubit couplings, yield time-periodic inversions in\nthe dynamical evolution, thus cancelling exactly the effects of quantum state\ndiffusion. We illustrate the method for spin systems on closed rings with XY\nresidual interactions, showing that it enables the massive storage of\narbitrarily large numbers of local states, and we demonstrate its robustness\nagainst several realistic sources of noise and imperfections.",
