As an experimental physicist

I am a condensed matter experimentalist with primary research interests regarding realization and improvement of superconducting circuits for quantum computation.

In my PhD research in Prof. Gershenson's lab at Rutgers University, I fabricated and characterized nanoscale aluminum Josephson junctions and circuit elements such as capacitors, inductors, microwave resonators, and qubits. Our recent progress was the successful demonstration of ten-fold T1 enhancement in protected state with bifluxon qubits.

In the meantime, I am also interested in making novel circuit components to enable new tools for superconducting qubits. For example, realizing large (kinetic) sheet inductances in disordered aluminum thin films (2 micro-Henry per square) which was used in later stage of development to serve as a superinductor for bifluxon qubits. Another example is Josephson junction-embedded resonators which enables compact resonators to improve connectivity and potentially higher quality factor due to less dielectric interfaces.

Before I pursued my PhD degree, I served 2+ years as a research and development engineer at Taiwan Semiconductor Manufacturing Company Limited (tsmc), focusing on development of fingerprint sensors with through-silicon-vias (TSV) technology, wafer backside processing and chip level packaging. The process integration includes wafer thinning and TSV reveals, backside metal redistribution layer formation, microbumping, chip stacking, and mold packaging.

As a hardware enthusiast

I am a “toolbox” person, so it is my personal endeavor to learn new hardware and expand my skill spectrum in process integrations.

My current research interest is to implement 3DIC technology in superconducting qubits to pave the path for scaling up future qubit platforms such as Si-spin qubits, surface ion traps or even the hybrids of qubits. Please do feel free to shoot me a message if you share similar thoughts, looking forward to exciting interactions with enthusiasts!

As a quantum developer

I started my quantum programming language with Qiskit ("I speak Qiskit" in short). And I also participated in quantum Hackathon to serve as coach or judges hosted by IBM Quantum. I am also a Qiskit advocate who dedicates in quantum education with visualization modules and quantum games.

If you happened to have both Qiskit and Pygame installed in your python environment, I would love to hear your thoughts on my previous quantum game called QShooter. The github repository can be found below, and I am currently porting it into LUA (pico-8) platform for more vintage feelings.

Currently the line in between software developers and hardware engineers in my field is still vague, and I feel quite fortunate to be born in this early stage of the history to participate the development of quantum engineering frameworks. As a result I am also actively looking for active discussions, educations, and brainstorming with energetic minds in the field of quantum education for K-12 and quantum games for kids!
