    • Chang, Jun-Tao; Zubairy, M. Suhail (American Physical Society, 2008)
      We describe a three-qubit quantum phase gate which is implemented by passing a four-level atom in a cascade configuration initially in its ground state through a three-mode optical cavity. The three qubits are represented ...
    • Kiffner, M.; Zubairy, M. Suhail; Evers, J.; Keitel, C. H. (American Physical Society, 2007)
      A two-mode single-atom laser is considered, with the aim of generating entanglement in macroscopic light. Two transitions in the four-level gain medium atom independently interact with the two cavity modes, while two other ...
