    • Fast noise in the Landau-Zener theory RID B-5617-2009 

      Pokrovsky, Valery L.; Sinitsyn, NA. (American Physical Society, 2003)
      We study the influence of a fast noise on Landau-Zener transitions. We demonstrate that a fast colored noise much weaker than the conventional white noise can produce transitions itself or can change substantially the ...
    • Quantum search protocol for an atomic array 

      Scully, Marlan O.; Zubairy, M. Suhail (American Physical Society, 2001)
      Quantum computers can, in principle, exceed the speed of ordinary computers by taking advantage of quantum coherence and entanglement. It is possible to find a "needle in a haystack" of N-1 straws in only rootN searches ...
    • Tunable phase control for subluminal to superluminal light propagation 

      Sahrai, M.; Tajalli, H.; Kapale, KT; Zubairy, M. Suhail (American Physical Society, 2004)
      We demonstrate tunable control of the group velocity of a weak probe pulse from subluminal to superluminal. The model is an extended Lambda-type system with two extra control fields and an extra energy level. Phase variation ...
