We presented our latest work at the Frontiers in Optics and Laser Science conference

Dr Koleva presented a poster on our latest work on ultrafast optical polarisation rotation through spin-photon entanglement in a charged quantum dot embedded in a microvillar cavity.

We modelled the spatial and temporal dynamics for the weak, intermediate and strong coupling regimes. The work also included new calculations of the ultrafast phase shift of the transmitted signal at the output cavity facet that can be measured experimentally. We carried out this work in collaboration with Prof. Christian Jirauschek and Dr Michael Haider of Technische Universität München.

The poster is entitled ‘Optical Polarization Rotation through Spin-Photon Entanglement in a Charged Quantum Dot-Micropillar System’

Our method is useful for realising high-fidelity photon polarisation states and conditional phase gates for photon-based quantum computing.
