  Adiabatic transport of information is a widely invoked resource in connection
with quantum information processing and distribution. The study of adiabatic
transport via spin-half chains or clusters is standard in the literature, while
in practice the true realisation of a completely isolated two-level quantum
system is not achievable. We explore here, theoretically, the extension of
spin-half chain models to higher spins. Considering arrangements of three
spin-one particles, we show that adiabatic transport, specifically a
generalisation of the Dark State Adiabatic Passage procedure, is applicable to
spin-one systems. We thus demonstrate a qutrit state transfer protocol. We
discuss possible ways to physically implement this protocol, considering
quantum dot and nitrogen-vacancy implementations.
