• Abstract: Solid-state quantum dots are promising candidates for efficient light-matter interfaces connecting internal spin degrees of freedom to the states of emitted photons. However, selection rules prevent the combination of efficient spin control and optical cyclicity in this platform. By utilizing a photonic crystal waveguide we here experimentally demonstrate optical cyclicity up to $\approx15$ through photonic state engineering while achieving high fidelity spin initialization and coherent optical spin control. These capabilities pave the way towards scalable multi-photon entanglement generation and on-chip spin-photon gates.

• Controlling photon polarisation with a single quantum dot spin [0.0]
  We demonstrate the control of giant polarisation rotations induced by a single electron spin. We find that the polarisation state of the reflected photons can be manipulated in most of the Poincar'e sphere, through controlled spin-induced rotations. This control allows the operation of spin-photon interfaces in various configurations, including at zero or low magnetic fields.
