Dr Koh Teck Seng

Biography
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.
