|MACIEY LEWENSTEIN, University of Hannover|
Diploma in physics at the Warsaw University. OPhD thesis at the University
of Essen. Since 1979-1994 employed in the Institute for Theoretical Physics
of Polish Academy of Sciences (Warsaw). Since 1986 faculty member there.
Numerous postdoc and research associate stays (Essen, Harvard, JILA, Saclay).
Since 1995 permanently employed at Saclay CEA. Since 1998 C4 Professor
and leader of the quantum optics
|I will review recent activities of Hannover gorup in modeling
quantum information processing with neutral cold atoms in optical microtraps.
I present the idea of realising "spatially delocalized" qubits, i.e. coding the qubit state as a presence in a given site of two microtraps. I will show, how one can realize quantum randoim walks with this idea.
Investigations of motion of atms in three microtraps will lead us to the idea of three lavel atom optics, and atom optics analogues of adiabatic Raman passage (STIRAP), elctromagnetically induced transparency, and coherent population trapping.
