    "abstract": "An electron-nucleon double spin(ENDOS) solid-state quantum computer scheme is\nproposed. In this scheme, the qubits are the nuclear spins of phosphorus ion\nimplanted on the (111) surface of $^{28}$Si substrate. An $^{13}$C atom on a\nscanning tunnelling probe tip is used both to complete single qubit and\ntwo-qubit control-not operation, and single qubit measurement. The scheme does\nnot require interactions between qubits, and can accomplish two qubits without\nthe use of SWAP gate.\n  This scheme is scalable, and can be implemented with present-day or\nnear-future technologies.",
