SUMMARY:Adiabatic control for efficient single photon absorption in free space and for quantum gates in optical lattices
DESCRIPTION:A technique is presented for achieving deterministic generation and
absorption of single photon
wave packets by single atoms in free space. It exploits basic features 
of stimulated Raman adiabatic passage. These procedures can be used as
basic building blocks for engineering
quantum communication protocols compatible with free space links relevant
for satellite-based
quantum communication.
Furthermore, a protocol for implementing a two qubit gate in an optical
lattice
is presented. The interaction between the neighbouring qubits is mediated
by a large ensemble of atoms in the superfluid phase. Adiabatic control
is used in order to tailor the local interaction between the single atoms
carrying the
qubits and the additional atoms in the superfluid phase. Using such a
large ensemble of atoms significantly increases the strength of the
non-local interaction between
neighbouring lattice sites leading to faster gate operations.
