III. Major Directions:

The mission of the thematic group is to build a platform of communication and discussion for researchers in the area of Quantum Information Science and Quantum Control in Taiwan with particular emphasis to enhance the internal collaborations and the international links. Research topics that may promote the collaboration and research of the core members are listed below.

      (1)   Temporal Steering and its applications
(2)   Steering from the relativistic quantum information perspective
(3)   Quantum Nonlocality & Device-independent Quantum Information
(4)   Quantum Hybrid Systems
(5)   Robust Quantum Control and non-Markovian Process Characterization


VI. Activities: 


Regular Seminars at NCKU

        Non-regular seminars at NTU





Young Researchers Forum on Quantum Information Science


Workshop on Quantum Science and Technology


V. Highlight of Results (2017-2018):

   Prof. Guang-Yin Chen and Prof. Yueh-Nan Chen study theoretically the bio-sensing capabilities of metal nanowire surface plasmons [1]. The results provide a feasible way, using single photons, to detect mutation-induced, or bleaching-induced, local defects or modifications of the FMO complex. In particular, they find that the change of the Fano lineshape in the scattering spectra further reveals that “site 5” in the FMO complex plays a distinct role from other sites. This theoretical prediction has been experimentally confirmed very recently [2].

   Prof. Yueh-Nan Chen collaborated with the group of Prof. Nori (Riken, Japan) and proposed that the temporal steering can be quantified via semidefinite programing, with a temporal steerable weight. It can be used to define a sufficient and practical measure of strong non-Markovianity [3]. Recently, this theoretical prediction has also been experimentally verified [4].
