Collaboration between Space and Naval Warfare Systems Center Pacific SSC Pacific and the Naval Research Lab NRL was initiated in 2015 and 2016 as part of the OSD Quantum Science and Engineering Program QSEP. The collaborations topic is to examine the effect of an electric-field on silicon carbide qubits as a unique contribution, as well as a general benefit in increasing knowledge in the quantum information field and working towards supporting demonstrations of quantum entanglement based on these qubits and quantum memories developed out of the silicon carbide system and other systems as necessary through the QSEP program. This years highlights included successful completion of a novel process flow for the construction of the tunable qubits, measurements of the optical emission from the devices, simulations of the tuning process, and progress for experimental validation of the concepts and for supporting entanglement demonstrations. A patent disclosure was filed on the concept of tunable silicon carbide qubits as well as a conference abstract was accepted to the SPIE 2017 nanoscience plus engineering conference for consideration in the quantum photonic devices section.
