Silicon Qubit Environment & Interface Program

The Silicon Qubit Environment & Interface Program, led by Prof Sven Rogge at UNSW Sydney, aims to couple qubits in a robust manner from the atomic nano-meter length scale to macroscopic coupling via photons. On the atomic scale we optimise the coupling between donor atoms while taking the complex nature of their charge density in silicon into account. To achieve macroscopic coupling we engineer electric-dipole coupling to spin qubits. This enables direct qubit-qubit coupling at the 100nm length scale and the coupling to microwave resonators that allows for chip scale coupling. Finally, an optical interface to spin qubits is investigated for long distance coupling based on rare-earth ions in silicon and integrated single-photon detectors in collaboration with ANU, Griffith, RMIT, and UNSW Canberra.
