Query: Tunneling transfer protocol in a quantum dot chain immune to
  inhomogeneity   We propose a quantum dot (QD) implementation of a quantum state transfer
channel. The proposed channel consists of N vertically stacked QDs with the
nearest neighbor tunnel coupling, placed in an axial electric field. We show
that the system supports high-fidelity transfer of the state of a terminal dot
both by free evolution and by adiabatic transfer. The protocol is to a large
extent insensitive to inhomogeneity of the energy parameters of the dots and
requires only a global electric field.
