摘要
We investigate the dynamics of a giant atom (or atoms) 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-atom system, the waveguide will induce the controllable individual and collective dissipation as well as effective interatom coupling. As a result, we can realize theoretically the robust entangled state preparation and nonreciprocal excitation evolution. We hope our study can be applied in quantum information processing based on a photonic and acoustic waveguide setup.
