Biography
Tzu-Chieh Wei received his B.A. and M.Sc. in physics from National Taiwan University
before the millennium. He earned his PhD degree in physics from the University of
Illinois in 2004. Afterwards, he held postdoctoral and research associate positions
at the University of Illinois, the University of Waterloo (in their Institute for
Quantum Computing), and the University of British Columbia. In 2011, he joined the
faculty of the C. N. Yang Institute and Department of Physics and Astronomy at Stony
Brook University.
Research Statement
As early as in his PhD study, Tzu-Chieh Wei worked on entanglement theory and its
applications to quantum phase transitions and on schemes of entangled photons for
applications in quantum information processing. He also did research on carbon nanotubes,
superconductivity, BEC, and optical lattices. His main theme of research has been
the interdisciplinary quantum information science and has contributed to the development
of the geometric measure of entanglement, quantum computational universality of two-dimensional
Affleck-Kennedy-Lieb-Tasaki (AKLT) states and the existence of the spectral gap in
some AKLT models, the use of symmetry-protected topological states for measurement-based
quantum computation, the QMA-hardness complexity for certain bosonic problems, and
applications of tensor-network methods in quantum many-body systems. He was also involved
with several milestone experiments in quantum information. His recent interest and
contributions include error mitigation for near-term quantum devices, quantum algorithms,
and quantum machine learning, and he has spearheaded the effort in creating a quantum
master’s program at Stony Brook University.
