Quantum computing PhD student · Fintech enthusiast · Singapore
These days I work on neutral-atom quantum computing in David Wilkowski’s group at NTU / CQT. Before that I spent a year on Singapore’s first homegrown superconducting quantum computer, a 20-qubit processor: error sources, gate fidelity, crosstalk, and machine-learning methods to improve qubit readout. I also wrote an open introduction to superconducting qubits.
I’ve been into crypto since 2019, way before I studied physics. I like zero-knowledge proofs, options and trading, so I tend to build around markets and privacy.
I write here in English and Chinese. The older posts are about school, part-time jobs, and a few poems.

Quantum-inspired optimisation everyone can check: simulated bifurcation races classical solvers and the exact optimum in your browser, with every number labelled measured, estimated or not run.
My part: solo build.
Mar–May 2026
An options DEX on Solana, built as a private OTC market: traders get competing quotes without revealing their budget.
My part: protocol design, the ZK prototype and the option flow. Rust/Anchor program on devnet.
A bilingual AI companion: a portable device and the web app behind it, where the character Yori keeps you company and helps you take the first small step.
A market that pays commuters to miss the crush: shift your trip off-peak and get paid once the shift is verified.
Private auctions for autonomous AI agents: a computing-resources marketplace with verifiable settlement.

Superconducting qubits Machine-learning methods for more reliable readout on CQT’s 20-qubit processor.
Trapped-ion addressing A dual-AOD laser setup for addressing one ion while keeping crosstalk low.
Proof systems Binius and sumcheck in Python; Lasso and Jolt-style lookups in Rust.
Introduction to superconducting qubits Open tutorials I compiled after teaching PH3410 Quantum Hardware: twelve chapters and twelve Python labs.

I had barely used a laser when I joined a trapped-ion lab. I built a two-axis beam-steering setup at 355 nm, lost the alignment over the December break, rebuilt it in three months, and later worked out what really limited it.

How a quantum mechanics course led me to Marco Tomamichel’s group at the Centre for Quantum Technologies, and what a summer of quantum cryptography taught me about what quantum mechanics can and can’t do.
