Query: Entanglement preparation and non-reciprocal excitation evolution in
  giant atoms by controllable dissipation and coupling   We investigate the dynamics of giant atom(s) in a waveguide QED scenario,
where the atom couples to the coupled resonator waveguide via two sites. For a
single giant atom setup, we find that the atomic dissipation rate can be
adjusted by tuning its size. For the two giant atoms system, the waveguide will
induce the controllable individual and collective dissipation as well as
effective inter-atom coupling. As a result, we can theoretically realize the
robust entangled state preparation and non-reciprocal excitation evolution. We
hope our study can be applied in quantum information processing based on
photonic and acoustic waveguide setup.
