QFort

Quantum technology, particularly quantum information science and the development of future electronics, is a major technology that can enhance societies and lead us into the Fourth Industrial Revolution. It lies at the heart of many future technologies, artificial intelligence, the Internet of Things, and their future development and potential are all based on and limited by the power of computation and communication. Over the past decade, NCKUI has invested significant resources and manpower towards quantum science and technology. This investment has led to the finest research outcomes in Taiwan and a new Center for Quantum Frontiers of Research and Technology (QFort). QFort focuses on three strongly correlated research directions: theory for quantum devices and quantum computations; superconductor-semiconductor (and other emergent materials) hybrid quantum devices and qubits; integrates scholars with different expertise – ranging from theoretical prediction to numerical simulation, epitaxial growth and material characterization – to achieve cutting-edge breakthroughs in quantum materials. 

New Possibility of Open Quantum System

Professor Yueh-Nan Chen in the Depart­ment of Physics and Assistant Professor Hong-Bin Chen in the Department of Engineering Science developed a method for the detection and certification of the nonclassicality of dephasing dynamics. After proving the feasibility of the Hamiltonian-ensemble simulation method, Hong-Bin Chen gave the theory a formal rewrite by describing and examining the dephasing in the frequency domain rather than in the time domain, as is generally done. This opened up a new path for research, is considered groundbreaking, and was published in Nature Communication in August2019 

BiFeO₃ – Higher Efficiency, Less Waste 

A research team led by Professors Jan-Chi Yang and Yi-Chun Chen of the Department of Physics have developed bismuth ferrite (BiFe03), a multi-digit memory material which is capable of recording eight logic states (0-7) simultaneously in a single memory unit. The application of multi-digit materials in conjunction with light control technology can greatly reduce memory storage volume and energy consumption/dissipation levels compared to existing memory devices. A report of this work was published in May 2019 in the prestigious international peer-reviewed journal Nature Materials.
