    "abstract": "Quantum decoherence is the major obstacle in using the potential of\nengineered quantum dynamics to revolutionize high-precision measurements,\nsensitive detection, or information processing. Here we experimentally\ndemonstrate that quantum state of a system can be recovered after the state is\ndestroyed by uncontrollable natural decoherence. Physical system is a cluster\nof seven dipolar-coupled nuclear spins of single-labeled 13C-benzene in liquid\ncrystal. 13C spin plays a role of a device for measuring protons\u0027 \"cat\" state,\na superposition of states with six spins up (alive) and six spins down (dead).\nInformation about the state, stored in the 13C spin, is used to bring the\nprotons\u0027 subsystem into the alive state, while the excess entropy produced by\ndecoherence is transferred to the \"measuring device\", the 13C spin.",
