What is the challenge of my research project? Why am I eager to do it?
Semiconductor quantum dots excel with on-chip integrability and the possibility to emit quantized light on demand. Quantum-dot based sources of quantum light may be the key to advance quantum information science. Two-photon processes in quantum dots show the potential to emit either highly entangled pairs of photons or a single photon, whose polarization state can be controlled all-optically.
Why did I choose this project?
The project A03 focusses on the down-conversion from the biexciton state via an optically induced virtual state, which leads to cavity enhanced single photon emission. In this theoretical contribution to the project I predict the quantum properties of the emitted single photon. This involves highly demanding numerical calculations.
