High-fidelity quantum state transfer through a dissipative quantum data bus*

Figure 1. Schematic illustrations of multiple-range adiabatic quantum state transfer from site A to B through an N trap optical lattice. Electron beams impacted on the traps are used to remove atom deterministically from the system. The loss rate at the lth trap is ${\gamma }_{l}$. Sender A and receiver B are time-dependently coupled to the two ends of the traps array. The neutral atom is assumed to be initialized in site A at the beginning of transport, while the other traps are empty. The atom can be transported through the lattice by adiabatically modulating JA and JB.
