Abstract

We have investigated the properties of Coherent Tunneling Adiabatic Passage (CTAP) with alternating tunneling matrix elements. This geometry provides an interesting route to long-range quantum transport that has not previously been considered in the donor in silicon paradigm. We introduce simplified coupling protocols, and transient eigenspectra as well as a realistic gate design for this transport protocol. Numerical simulations of the electrostatic landscape have been performed and from this we make estimates of the conditions required for adiabatic operation.
