Context

Quantum technologies have the potential to revolutionise the world in many aspects. Quantum colour centres in in wide bandgap semiconductors have recently emerged as a promising platform, since they can incorporate quantum systems, which can be scaled up by industrial processing.
Along these lines, we have recently shown that individual colour centres can be integrated into silicon carbide nanophotonic waveguides with littletono degradation of spinoptical coherences.
These finding define the strategy for developing a scalable quantum technology architecture.
Our strategy is to establish an onchip photonic quantum communication link between two colour centres. The idea is to perform photonic interference experiments using onchip beamsplitters, which enables direct entanglement generation between two separated colour centres. With this milestone demonstration, we strive to kickstart subsequent developments towards a truly scalable distributed quantum computing architecture.

Mission

The objective of this PhD thesis is to demonstrate photonic interference between two colour centres on a silicon carbide photonic chip. By characterising the quality of this interference for the first time, we will be able to clearly define the research direction towards scalable quantum computing architectures.
The initial part of this thesis comprises setting up our new optical cryostat platform, which is based on a combination of standard confocal microscopy, and direct fibretochip coupling. In the second step, you will benefit from our ongoing activities towards quantum photonic silicon carbide chips in which we generate colour centres in waveguides and onchip beamsplitters.
You will determine the ideal wavelength tuning mechanisms for colour centres, considering both electric tuning (Stark shift) and mechanical tuning (laserinduced strain). Subsequently, you will characterise these photonic quantum devices and identify suitable ones for the interference experiments between two colour centres. This then will allow you to implement onchip twophoton interference between separated colour centres, including a demonstration of photonmediated entanglement generation between two colour centres, i.e., the central building block of a distributed quantum computing architecture.
