I will outline our vision towards the deployment of quantum technology based on a transition from heritage systems towards semiconductor quantum chips “made in Europe”.

After presenting some use cases and quantum hardware developments, I will outline our approach towards the initiation of the semiconductor age of quantum technology.

 

 

More detailed, our ambition is the integration of quantum systems on a chip-scale, which is a promising route towards an improved accessibility of quantum technologies, leveraged by lower costs, higher reproducibility, and more complex functionalities.

 

Our approach lends inspiration from classical computers that spread across the society after the transition from vacuum tubes to semiconductor chips. We envision a similar quantum revolution, enabled by semiconductor technology.

 

Towards this mission, important semiconductor quantum systems cover quantum dots, spins and photons in silicon, as well as atomic defects in silicon or silicon carbide – so-called “colour centres”.

 

In recent years, quantum colour centres in silicon carbide are on a steep rise, closely competing with heritage diamond colour centres.
In this regard, I will show our recent work on nanophotonic integration of colour centres, as well as our advances on using nuclear spins as qubits.

 

I will also provide an overview of our ongoing activities at the Luxembourg Institute of Science and Technology (LIST), which intend to transition academic nano-fabrication processes to methods to standard methods of the industrial sector. Here, it is crucial to ensure that all fabrication processes are “quantum-grade”, avoiding parasitic background fluoresce, as well as excessive charge noise. In this quest, we are currently setting up a high-throughput cryo-optic quantum characterisation platform through which we want to significantly accelerate the discovery and reproducibility of ideal quantum fabrication techniques. With the ideal processes developped, we see a strong potential for quantum communication and computing tasks.
