Recent cryogenic platform developments from Oxford Instruments for quantum computing and quantum technology research
Dr Harriet van der Vliet, Oxford Instruments NanoScience

In this webinar you will hear an update on the technological advancements and cryogenic platform developments from Oxford Instruments NanoScience, focusing on our data centre installations, customer research and our recent introduction of QCoDeS to our Proteox platform.

The ProteoxS, the most compact dilution refrigerator, with the same specifications as its larger family members which is ideal for spin qubit applications, will be introduced with latest data presented from the platform. This is a dilution refrigerator that is perfect not only for small numbers of qubits and fundamental research, but as a tool for educating the quantum workforce, from cryogenic technicians to quantum engineers in academic labs.
At the other end of the scale, the ProteoxQX, the only true modular, scalable solution for the 1000+ qubit regime will be presented, a system suitable to allow users to deliver their roadmaps and achieve their national goals.

Atomic-scale processing techniques for quantum device fabrication
Dr Nicholas Chittock, Oxford Instruments Plasma Technology

Current generation quantum devices are limited by losses. A primary source of these losses is poor quality interfaces and damaged surfaces, which are generated during device fabrication. To minimise (or avoid) the formation of these loss channels in quantum devices advanced nanofabrication techniques are required.

In this webinar, we will discuss the application of atomic layer deposition (ALD) and atomic layer etching (ALE) to materials relevant for quantum applications. ALD of superconducting nitrides for superconducting nanowire single photon detectors and through silicon vias will be discussed. While for ALE, the use of both anisotropic and isotropic ALE for low damage material removal for superconducting, colour center and waveguide applications will be highlighted. Utilising processing techniques that are inherently low damage may enable the fabrication of quantum devices with lower losses, helping to provide longer coherence times and quantum devices with higher Q-factors.
