  Adiabatic methods are potentially important for quantum information protocols
because of their robustness against many sources of technical and fundamental
noise. They are particularly useful for quantum transport, and in some cases
elementary quantum gates. Here we explore the extension of a particular
protocol, dark state adiabatic passage, where a spin state is transported
across a branched network of initialised spins, comprising one `input' spin,
and multiple leaf spins. We find that maximal entanglement is generated in
systems of spin-half particles, or where the system is limited to one
excitation.
