Senior Research Fellow at The University of New South Wales, Sydney Australia (May 2021 – current)

  • I am currently working on the implementation of spin-photon coupling in a silicon quantum dot qubit devices with on-chip fabricated superconducting microwave resonators to enable distant qubit coupling and realization of scaled-up quantum processor.

Head of Quantum Device Fabrication at IQM Quantum Computers, Finland (Jun 2019 – March 2021)

  • I led a team of quantum engineers, focusing on the design and fabrication of scalable superconducting quantum computing with circuit refrigeration for qubit reset and utilizes 3D integration technologies.
  • I also led the establishment of a cleanroom facility to manufacture commercial superconducting quantum computers.

Senior Scientist at Microsoft Quantum, Sydney Australia (Jun 2018 – May 2019) 

Research Fellow at The University of New South Wales, Sydney Australia (Oct 2015 – Jun 2018) 

  • My research focused on the design and development of silicon quantum dot architecture with fabrication process suitable for scalable quantum computing. This architecture is based on metal—oxide—semiconductor compatible aluminum multi-layer gating technology. I played an integral role in this novel process in Prof. Andrew Dzurak’s group. I have fabricated devices which meet the experiment requirement for current state-of-the-art two-qubit logic gates operation and facilitated the first demonstration of full two-qubit state tomography and randomized benchmarking in silicon quantum dot spin qubit platform, published in Nature

Research Fellow at The National University of Singapore, Singapore (Oct 2012 – Sep 2015) 

  • I assisted the Director, Prof. Antonio Castro Neto to establish the Micro and Nano Fabrication Facilities under the National University of Singapore and Singapore National Research Foundation (NRF) start-up grants, worth S$40 million. The cleanroom facility, named CA2DM Micro- and Nanofabrication Facilities comprise a state-of-the-art 800 sqm Class 100 and 1000 areas dedicated to 2D materials research such as graphene. I established and supervised a competent cleanroom operation and management team. I fabricated graphene bolometer devices which have produced results published in Nature
