Query: Scheme for the implementation of optimal cloning of arbitrary single
  particle atomic state into two photonic states   We present a feasible scheme to implement the $1 \to 2$ optimal cloning of
arbitrary single particle atomic state into two photonic states, which is
important for applications in long distance quantum communication. Our scheme
also realizes the tele-NOT gate of one atom to the other distant atom trapped
in another cavity. The scheme is based on the adiabatic passage and the
polarization measurement. It is robust against a number of practical noises
such as the violation of the Lamb-Dicke condition, spontaneous emission and
detection inefficiency.
