Dr Koh Teck Seng

Lecturer, School of Physical & Mathematical Sciences
Director, Odyssey Leaders in Science Programme

Dr Koh Teck Seng

BSc (Hons) Physics, National University of Singapore (1998)
PGDE (Education), NIE, Nanyang Technological University (1999)
PhD Physics, University of Wisconsin-Madison (2012)
Research Interests
(1) Quantum Information and Quantum Computation
I study quantum computation protocols applied to quantum dot spin qubit systems, in the context of Noisy Intermediate-Scale Quantum (NISQ) devices.

(2) Multi-scale perturbative quantum master equation approaches
I am interested in developing perturbative quantum master equation approaches to quantum transport.


** Undergraduate students looking to do an FYP with me: please contact me before the end of Year 3 Semester 2, so that we can work on a paid internship under the Odyssey research program over the special term that can lead into the FYP for Year 4.

Students currently working with me:
1. Mr Jeremy Lian (FYP Student: Computational Thinking in Physics)
2. Mr Woo Ying Zheng (FYP Student: Tunneling Noise in Quantum Dot Spin Qubits)
3. Mr Zaw Lin Htoo (FYP Student: Randomized Benchmarking)
4. Mr Radha Krishnan (PhD Student: Cotunneling Spectroscopy in Double Quantum Dots ;with Asst Prof Bent Weber)
