    "abstract": "The current proposals for the realization of quantum computer such as NMR,\nquantum dots and trapped ions are based on the using of an atom or an ion as\none qubit. In these proposals a quantum computer consists from several atoms\nand the coupling between them provides the coupling between qubits necessary\nfor a quantum gate. We discuss whether a {\\it single} atom can be used as a\nquantum computer. Internal states of the atom serve to hold the quantum\ninformation and the spin-orbit and spin-spin interaction provides the coupling\nbetween qubits in the atomic quantum computer. In particular one can use the\nelectron spin resonance (ESR) to process the information encoded in the\nhyperfine splitting of atomic energy levels. By using quantum state engineering\none can manipulate the internal states of the natural or artificial (quantum\ndot) atom to make quantum computations.",
