Post Event Brief

He highlighted the “ugly” side in semiconductor foundry facilities that may cause potential surface damage, resulting in high coherence and large variability for large scale fabrication. He also shared some examples on the direct and indirect consequences of material limitations of superconducting quantum circuits. He followed on by explaining the investigation of resonators to improve qubit performance, further discussing some recent results of materials control such as both superconducting and silicon spin qubit platform. He also shared the process challenges and emphasised the need of high uniformity, high yield, high process control qubit application. Lively discussion ensued at the end of the session with numerous questions raised from attendees. The session wrapped up at 11.30 am with Prof Aaron Thean presenting Dr Kristiaan with a gift as a token of appreciation.
