We investigate a periodic array of metallic nanoparticles as a channel for short distance on-chip nanophotonic quantum communication. The transfer of a quantum state, encoded in the form of a single-qubit wavepacket, is studied under ideal conditions. The effects of loss in the metal are then included in order to put the investigation into a more practical setting and quantify the performance of realistic plasmonic nanoparticle arrays as quantum channels. Our study highlights the benefits as well as the drawbacks associated with nanophotonic periodic systems that use surface plasmons in the quantum regime. The techniques introduced in this work and the results obtained from them are aimed at contributing to the study of plasmonic nanostructures for quantum control applications and probing nanoscale optical phenomena.
