Associate Professor, Tokyo University of Agriculture and Technology

**Topic: **Information Theoretic Cryptography (1/2)

**Abstract: ** In this tutorial we will cover the basic topics of secure transmission and secure computation. The list of topics to be covered include universal hash functions, authentication, CPA/CCA secure encryption, secure computing and oblivious transfer, bit commitment, composable security, zero-knowledge proofs and completeness of OT. These are standard topics for a cryptography course, but our exposition will focus on the information theoretic perspective. In particular, we will provide information theoretic proofs of security, under the assumption of availability of correlated randomness.

Assistant Professor, National University of Singapore

**Topic: **Information-Theoretic Limits for Inference, Learning, and Optimization

**Abstract: ** The field of information theory was introduced as a means for understanding the fundamental limits of data compression and transmission, and has shaped the design of practical communication systems for decades. These lectures will be based on the emerging viewpoint that information theory is not only a theory of communication, but a far-reaching theory of data that is applicable to seemingly unrelated problems such as estimation, prediction, and optimization. This perspective leads to principled approaches for certifying the near-optimality of practical algorithms, as well as understanding where further improvements are possible. I will provide an introduction to some of the main ideas and insights offered by this perspective, cover some commonly-used tools such as Fano's inequality and Le Cam's method, and present examples including group testing, graph learning, sparse regression, and black-box function optimization.

**Topic: **Some facets of information theoretical graph analytics

**Abstract: **This course will present two aspects of graph analytics, namely node centrality and clustering, with emphasis on methods coming from information theory. Datasets will be shared and examples will be given using Jupyter notebooks, thus providing an (optional) introduction to NetworkX.

**Biography: **F. Oggier is an associate professor in the division of mathematical sciences, Nanyang Technological University, Singapore. Her interests are in the areas of algebraic coding theory at large, security, and more generally applied algebra.

Professor, Tata Institute of Fundamental Research

**Topic: **An introduction to quantum computation and information

**Abstract: **We will start with a comparison of quantum probability and classical probability by considering the task of computing the AND of two bits, one of which is with with Alice and the other with Bob. We will build on this and set up the framework of quantum circuits. We will review standard quantum algorithms based on an efficient circuit for Quantum Fourier Transform and Phase Estimation. We will discuss the entropy of quantum states, and some standard coding theorems in quantum information theory. We will apply these ideas to derive some lower bounds in quantum communication complexity.

**Biography: **Jaikumar Radhakrishnan works in the area of Theoretical Computer Science, and is interested in applying algebraic, combinatorial, probabilistic and information theoretic tools for studying computational problems. He has contributed results in Approximation Algorithms, Circuit Complexity, Communication Complexity and Quantum Computing. Jaikumar received his BTech degree in Computer Science and Engineering from Indian Institute of Technology, Kharagpur, in 1985. He received his PhD degree in Computer Science from Rutgers University in 1991. Since 1991, he has been at the Tata Institute of Fundamental Research, Mumbai, where he is currently a Senior Professor in the School of Technology and Computer Science.
