Solid-state photonic quantum systems have matured dramatically, and time is now mature to merge small-scale quantum systems into larger quantum architectures for advanced functionalities. We exploit single quantum dots embedded in photonic nanostructures as qubits for quantum-information processing. Recent highlights include the demonstration of single-photon switching controlled by a single spin chiral photon-emitter coupling. The platform is considered a promising pathway to on-demand multi-photon entanglement generation and deterministic quantum gates for quantum-information processing applications We currently have an opening for a 2 year (with possibility of extension) postdoc position in the Quantum Photonics Group at the Niels Bohr Institute. The project is embedded in the Center of Excellence Hybrid Quantum Networks Hy‑Q and the EU Quantum Internet Alliance.
The project concerns experimental generation of multi-photon entangled states by coherently coupling and controlling a single spin in a quantum dot embedded in a waveguide. Pioneering work on quantum dots in bulk samples [Science 354, 434 (2016)] has shown the exciting potential of this approach. Following recent theoretical proposals [Phys. Rev X 7, 041023 (2017)], we intend to generate on-demand all-photonic quantum repeater states.
