    "abstract": "We present a model for quantum computation using n steady 3-level atoms or\n3-level quantum dots, kept inside a quantum electro-dynamics (QED) cavity. Our\nmodel allows one-qubit operations and the two-qubit controlled-NOT gate as\nrequired for universal quantum computation. The n quantum bits are described by\ntwo energy levels of each atom/dot. An external laser and n separate pairs of\nelectrodes are used to address a single atom/dot independent of the others, via\nStark effect. The third level of each system and an additional common-mode\nqubit (a cavity photon) are used for realizing the controlled-NOT operation\nbetween any pair of qubits. Laser frequency, cavity frequency, and energy\nlevels are far off-resonance, and they are brought to resonance by modifying\nthe energy-levels of a 3-level system using the Stark effect, only at the time\nof operation.",
