Quantum Computation And Sensing On Network

Speaker:  Yuki Takeuchi, NTT Basic Research Laboratories

Abstract: Quantum computers are expected to outperform modern computers (i.e., classical computers) including supercomputers. From the high expectations, several companies and universities have devoted huge efforts toward the realization of full-fledged quantum computers. On the other hand, due to their physical sizes and the necessity of a cryogenic environment, it should be hard to personally own first-generation full-fledged quantum computers. A possible approach to overcome this issue is blind quantum computation, which is a secure cloud quantum computing protocol. By using it, a client, who would like to solve some hard problem, but his/her quantum capability is weak, can delegate the hard problem to a remote quantum computer without revealing what the answer is. Recently, we have extended it to quantum sensing, i.e., have proposed secure cloud quantum sensing. Quantum sensors also have several advantages compared with modern sensors (i.e., classical sensors) in terms of sensitivity, spatial resolution, and so on. In short, the combination of quantum information processing and network should achieve a society where anyone can enjoy quantum advantages from anywhere.

In this talk, first, I introduce some basic concepts of quantum information processing. Then, I explain the current status of cloud quantum protocols and review our recent theoretical and experimental results.

From 5G To 6G: Towards A Ubiquitous Network With Intelligent Air Interface

Speaker: Chu-Hsiang Huang, Qualcomm

Abstract: Fifth generation (5G) cellular communication system provides a flexible system architecture that enables wireless communication technology to penetrate different verticals and connect various devices. Since 5G devices began to appear in the market, we have seen connected systems implemented across multiple use cases in different scenarios, e.g., vehicular network, high speed train, broadcast, and even satellite communications. However, emerging application scenarios under different conditions and with diverse objectives bring new challenges to traditional wireless system design methodology, which mainly relies on abstract models to capture the environment accurately and develop algorithms accordingly. Applying machine learning to develop AI models applicable to various application scenarios becomes a promising direction for designing wireless communication systems. Therefore, creating a new generation of machine learning-based intelligent air interface, which can adapt to different conditions, is a key technology for successfully developing and deploying wireless communication systems to cover all the use cases envisioned by 5G, 6G, and beyond. In this tutorial, we start with the flexible system architecture in the 5G standard, and explain how connected systems in different scenarios can be developed from the 5G system architecture. Then we show how machine learning can help to develop AI models in various wireless communication system use cases, and the challenge to design an intelligent air interface leveraging the vast capability of machine learning methodology, to provide a promising vision to the future 6G systems.

Trustworthy Machine Learning Systems Under Adversarial Environments

Speaker: Ning Wang, University of South Florida

Abstract: Modern AI systems, particularly with the rise of big data and deep learning in the last decade, have greatly improved our daily life and at the same time created a long list of controversies. Generative ML models used for art creation have been used by fraudsters to generate deepfakes; well-trained language models have been shown to exhibit generalizability deficiency and intrinsic bias; machine learning (ML) models have been demonstrated to leak sensitive information about the data owners. Meanwhile, AI systems are often subject to malicious and stealthy subversion that jeopardizes their efficacy, represented by model poisoning in the training and adversarial data generation in the testing. It is evident that security, privacy, and robustness have become more important than ever for AI to gain wider adoption and societal trust. This talk will introduce evasion attack, poisoning attack, inference attack, and their corresponding countermeasures.
