Temporary Research Assistant (Hui Khoon's group)

Q: What qualifications do I need to apply for this Temporary Research Assistant role?

Undergraduate degree in Physics or Computing is essential. Candidates should have quantum computing knowledge , particularly in numerical stabilizer simulation for BB codes . Direct experience building a simulator for these codes is highly valued. The role is ideal for someone who has completed a final-year project on this topic at NUS. When preparing your application, check out our guide on how to write a winning academic CV .

Q: What exactly will I be working on in this numerical simulator project?

You will complete and optimize a numeric simulator for the Bicycle Bivariate (BB) good q-LDPC code . Key tasks include speeding up an existing BP-OSD decoding algorithm by converting it to C++ and applying optimizations for the [[144,12,12]] code . You'll also explore the fail-fast technique to accurately estimate logical error rates for high-distance codes. If time permits, you may investigate performance under general noise models. This builds on a previous NUS Physics Final-Year Project . For more context on what research assistants do, see our research assistant job overview .

Q: What programming languages and skills are required?

Strong coding ability in Python and C++ is a must. You will need to convert existing Python code to C++ and optimize it for performance. Experience with numerical simulation in quantum computing , especially with stabilizer codes, will be key. The role also demands familiarity with BP-OSD decoding and parallelization techniques. If you are looking to strengthen these skills, check out our tips for excelling as a research assistant (many apply globally).

Q: How long is the appointment, and can it be extended?

This is a temporary, three-month contract to complete specific research tasks. There is no mention of extension in the job description, so the role is strictly fixed-term . The academic calendar might influence the start date, but it's not specified. If you seek long-term roles, explore more research assistant positions on our research assistant jobs page .

Q: Who will I be working under, and which research group?

You will join the research group of HK Ng at the Centre for Quantum Technologies (CQT) at NUS. The project is part of Hui Khoon's group (likely co-supervised). The group focuses on quantum error correction and code simulation. Learn more about similar roles on our research assistant listings .

Job Description

To build a numerical simulator for the Bicycle Bivariate (BB) good q-LDPC code.

The hired staff will complete remaining tasks leftover from their NUS Physics Final-Year Project on the same topic.

The staff will build a numerical simulator for the BB code, incorporating the simulator into the existing code simulation infrastructure within the group of HK Ng at CQT.

Specific tasks to be completed in the three months:

Speed up existing code with decoding algorithm BP-OSD, converting it to C++ and optimizing the code performance, possibly incorporating optimizations/specializations to the [[144,12,12]] code.
Explore the possibility of applying the “fail-fast” technique to simulating the BB code within our simulator, for accurate estimating of the logical error rates for high-distance codes.
(Time permitting) Explore performance of BB code under general noise.

Qualifications

Undergraduate degree in Physics and/or computing. Quantum computing knowledge, with direct experience in building numerical stabilizer simulator for BB codes. Strong coding ability (e.g., Python, C++).
