| contents | Fast long-range interactions between distant quantum dots in arrays remains an unsolved issue, which can be key to solve scalability issues in quantum simulation and computation processes, particularly related to the overhead associated with quantum error correction schemes. Furthermore, transport between static and moving quantum dots, relevant in surface acoustic wave induced experiments, has not been studied in detail. This article presents a paradigmatic model for picturing this process, where non-adiabatic terms driving a two-state transfer process are derived and discussed. Moreover, the main effects in the spin state of the electron and its effect on the transfer probability of the loading are analyzed including the most relevant interaction in semiconductor heterostructure induced 2 dimensional electron gases i.e. the Rashba-Dresselhaus terms. |
