Post Event Brief
On Nov 18th, SHINE hosted the Quantum Science Talk given by Dr.Kristiaan De Greve, Scientific Director and Program Director of Quantum Computing of imec, Belgium. Held at the campus of College of Design and Engineering, the response to the talk was overwhelming with close to 80 turn-up. The talk commenced at 10:30 am with Prof Aaron Thean, Director of SHINE centre, kicking things off.
During the talk, Dr Kristiaan spoke about factory mean and novelty of some activities of phenomena of qubit platform as well as the recent collaboration with NUS on photonics communication. He further shared about spin qubit superconducting and advantages of advanced manufacturing technology.
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.
