Institute for Interdisciplinary Information Sciences (IIIS)

Institute for Interdisciplinary Information Sciences (IIIS) established on December 30, 2010, held the inauguration ceremony on January 15, 2011. Prof. Andrew Chi-Chih Yao, Dean of the Institute, is a world-leading computer scientist, winner of the A.M. Turing Award in 2000, member of the Chinese Academy of Sciences,  foreign member of the US National Academy of Sciences and the American Academy of Arts and Sciences. The Institute aims to become one of the leading research centers on interdisciplinary information sciences in the world as well as to offer a habitat for the research and education of computer science and quantum information science in China.

The development of information science and technology has paved the way for modern civilization while computers, communication technologies and Internet, which are indispensable in our modern society, pervade all parts of human activity. The further development of information science in the 21st century depends on the exploration of new fundamentals and methods, the most effective method of which lies in the interaction between information science and other disciplines. IIIS at Tsinghua University led by Prof. Andrew Chi-Chih Yao is devoted to promoting the innovative development of information science and cultivating the next generation of scientific talents with extensive background knowledge in China. It is primarily engaged in the interaction of information science and other disciplines, physics, mathematics, as well as life science and social sciences in particular in the future while conducting effective research in emerging disciplines and nurturing talents with distinctive characteristics.

IIIS is an umbrella institute hosting four research organizations, namely Institute for Theoretical Computer Science (ITCS), Center for Quantum Information (CQI), Tsinghua-Ant Joint Research Laboratory for Digital FinTech (JRLDF), and Tsinghua University-China Quantum Technologies Corporation Joint Laboratory for Quantum Network (JLQN). IIIS also used to host four international research centers in the past few years, namely Tsinghua-MIT-CUHK Research Center for Theoretical Computer Science (CTCS), Tsinghua-Michigan Joint Center for Quantum Information (JCQI), Tsinghua-Waterloo Joint Center for Quantum Computing (JCQC), and Tsinghua-Aarhus Center for the Theory of Interactive Computation (CTIC).


I. Computer Science

ITCS founded in 2005 emphasizes on the interaction between theoretical computer science and mathematics. With a mission to build a super-highway for CS education and research in China, its international faculty team has played an important role in teaching, research, talent recruitment and academic exchanges.

JRLDF founded in 2016 focuses on the cutting-edge research in financial security, block-chain technology, artificial intelligence and robo-advisor.

CTCS inaugurated in June 2010 is the first joint venture of its kind that MIT has established in China.

CTIC founded in January 2011 focuses on foundational topics within the theory of computation using mathematical methods.

2. Physics

CQI founded in January 2011 focuses on the interaction of computer, information science and physics as quantum Information provides a new technology in the post-Moore era and has explored new fundamentals and methods for the development of information science.

JCQI founded in July 2011 aims to establish an international first-class platform and center for talent cultivation in quantum information in Tsinghua University.

JCQC founded in April 2012 focuses on the study of quantum computing and the development of quantum computers.

JLQN founded in September 2016, aims to integrate academic and corporate resources, cooperate in quantum information and quantum measurement with high-qualified research, and will focus on key quantum devices in long range quantum networks.

Prof. Andrew Chi-Chih Yao, Dean of IIIS, is world-leading computer scientist and winner of the A.M. Turing Award in 2000. The Turing Award is recognized as the “highest distinction in Computer Science” and the “Nobel Prize of computing”. Prof. Yao is the first Asian scholar to win the award since its establishment and the only Chinese laureate so far. Prof. Yao has a PhD in Physics from Harvard University and a PhD in Computer Science from the University of Illinois. His road to success has been a powerful example showing the importance of developing interdisciplinary information sciences.

Led by Prof. Andrew Chi-Chih Yao, IIIS has built up a strong international faculty team and is currently carrying out research in Theoretical Computer Science, Quantum Information, Security Computing, Network Science and Machine Intelligence. Specifically speaking, Theoretical Computer Science research at IIIS includes Computational and Communication Complexity, Algorithm Design and Analysis, Theory of Computation, Quantum Computing, Computational Logic and Computational Geometry,Quantum Information includes Quantum Computing, Quantum Memory, Quantum Communication, Quantum Network, Quantum Cryptography, Quantum Simulation, Quantum Measurement, Quantum Sensor and Many-body Theory. Cyber Security includes Computing Information Theory and Cyber Security, Cryptography, Cryptographic Theory and Protocols, Data Security, System Security and Network Security. And Network Science includes Computer Networks and Algorithm, Wireless Sensor Network, Complex Network, Social Network, Financial Network, Smart Grid, Network Optimization and modeling of and theoretical research on various complex systems (including financial and social systems). 

In the International Academic Review on Computer Science and Technology of Tsinghua University in August 2010, the committee has been impressed by the creation and progress of the institute under the leadership of Prof. Andrew Yao. They have been pleased to see the high level international academic activities developing around ITCS, which include the visits by a series of world-class experts in computer science, the student intern programs, and the establishment of collaborative programs with world leading institutions. ITCS has already had considerable positive impact on Tsinghua’s computer science program as part of its endeavour to become a world-class program.
