Spin-photon interface using InAs quantum dots

The spins of electrons and holes confined within InAs quantum dots can be used as qubits within spin quantum networks. The spins interact strongly with photons, and this provides the basis for a spin-photon interface, enabling transfer of quantum information between separated spin qubits using photons. In our research group we have developed a spin-photon interface using chiral effects in nano-photonic waveguides, where the spin information couples to the direction of the photon that is emitted. Our goal now is to optimize the interface using the Purcell effect to enhance the light-matter interaction. The project will involve advanced experimental work using state of the art techniques of nanophotonic spectroscopy, with scope for numerical modelling to optimize the devices using advanced software packages.
