    "abstract": "It is proposed that the state space of a quantum object with a complicated\ndiscrete spectrum can be used as a basis for multiqubit recording and\nprocessing of information in a quantum computer. As an example, nuclear spin\n3/2 is considered. The possibilities of writing and reading two quantum bits of\ninformation, preparation of the initial state, implementation of the \"rotation\"\nand \"controlled negation\" operations, which are sufficient for constructing any\nalgorithms, are demonstrated.",
