Koh Teck Seng is a physicist who conducts theoretical research in quantum computing, especially quantum devices. From his interactions with the quantum community, he has now come to believe that quantum computers are an engineering challenge awaiting realization. Ironically, he prefers to have a technology detox every now and then, sit silently in meditation and enjoy the mental freedom.

One of his favourite quotes comes from Jack Kornfield, “Remember when computers were going to mean you would have lots of free time? How has that worked out for you?”

Research Statement

My research is on quantum computer architectures in semiconductors. Currently, the focus is on how to make quantum bits work better in the noisy solid state environment. Ultimately, the broad goals in this field is to make progress towards a fully fault-tolerant quantum computer.

My other interests relate to the philosophical and humanistic aspects of quantum theory and quantum technology. I find questions pertaining to the nature of reality deeply fascinating, and ask questions of the ethics of emerging quantum technology as well.
