Venue: Room 308, Chow Yei Ching Building, The University of Hong Kong
Speaker(s): Professor Chang Wen Chen
Remark(s): Professor Chang Wen Chen
The Chinese University of Hong Kong, Shenzhen China &
State University of New York at Buffalo, USA
Date: June 11, 2019 Tuesday
Time: 3:00pm
Venue: Room 308, Chow Yei Ching Building, The University of Hong Kong
Abstract:
The worldwide flourishing of the Internet of Things (IoT) in the past decade has enabled numerous new applications through the internetworking of a wide variety of devices and sensors. More recently, visual sensors has seen their considerable booming because they usually capable of providing richer and more versatile information. Internetworking of large scale visual sensors has been named Internet of Video Things (IoVT). IoVT has its own unique characteristics in sensing, transmission, storage, and analysis, which are essentially different from conventional IoT. These new characteristics of IoVT are expected to impose significant challenges to existing technical infrastructures. In this talk, an overview of recent advances in various fronts of IoVT will be introduced and a broad range of technological and system challenges will be presented.

Title: Some perspectives on relativistic causality
Time: 02:00pm
Venue: Room 308, Chow Yei Ching Building, The University of Hong Kong
Speaker(s): Professor Pawel Horodecki
Remark(s): Professor Pawel Horodecki
Gdańsk University of Technology
Poland
Date: June 3, 2019 Monday
Time: 2:00 - 3:00pm
Venue: Room 308, Chow Yei Ching Building, The University of Hong Kong
Abstract:
We shall discuss two perspectives on relativistic causality. The first one is based on discrete systems statistics and shows that minimal assumption on correlation boxes from the perspective of relativistic causality leads to a correlation picture that goes fat beyond standard no-signaling paradigm. The second analysis involves an analysis of dynamics of potential continuous statistics of single system in a quantum-like, linear or not, theory. The main result provides the condition under which such dynamics may be causal.
About the speaker:
Pawel Horodecki graduated from Gdańsk University. He is currently Professor and lecturer at Gdańsk University of Technology, Professor and group leader in International Centre for Theory of Quantum Technologies. His research includes contributions to theory of quantum entanglement and quantum communication, including co-discovery of bound entanglement phenomenon and quantum entanglement witnesses. His research interests are quantum information and foundations of quantum physics.

Title: Memory effects in quantum metrology
Time: 02:00pm
Venue: Room 308, Chow Yei Ching Building, The University of Hong Kong
Speaker(s): Yuxiang Yang
Remark(s): Yuxiang Yang
Institute for Theoretical Physics ETH
Zurich
Date: May 31, 2019 Friday
Time: 2:00 - 3:00pm
Venue: Room 308, Chow Yei Ching Building, The University of Hong Kong
Abstract:
Quantum metrology concerns estimating a parameter from multiple identical uses of a quantum channel. We extend quantum metrology beyond this standard setting and consider estimation of a physical process with quantum memory, here referred to as a parametrized quantum comb. We present a theoretic framework of metrology of quantum combs, and derive a general upper bound of the comb quantum Fisher information. The bound can be operationally interpreted as the quantum Fisher information of a memoryless channel times a dimensional factor. We then show an example where the bound can be attained up to a factor of two. With the example and the bound, we show that memory in quantum sensors plays an even more crucial role in the estimation of combs than in the standard setting of quantum metrology.
About the speaker:
Yuxiang Yang is a postdoctoral fellow at the Institute for Theoretical Physics, ETH Zurich. He holds a PhD in Computer Science from The University of Hong Kong and a BS in Physics from Tsinghua University. In 2017 he was awarded a Microsoft Research Asia Fellowship for his work in quantum information theory. His research aims to identify quantum advantages in communication and computation, and to design optimal protocols for the next generation of quantum computing devices

Title: Quantum Shannon theory with superpositions of trajectories
Time: 02:00pm
Venue: Room 308, Chow Yei Ching Building, The University of Hong Kong
Speaker(s): Hlér Kristjánsson
Remark(s): Hlér Kristjánsson
Department of Computer Science
University of Oxford
Date: May 24, 2019 Friday
Time: 2:00 - 3:00pm
Venue: Room 308, Chow Yei Ching Building, The University of Hong Kong
Abstract:
Shannon’s theory of information was built on the assumption that the information carriers were classical systems. Its quantum counterpart, quantum Shannon theory, explores the new possibilities arising when the information carriers are quantum systems. Traditionally, quantum Shannon theory has focused on scenarios where the internal state of the information carriers is quantum, while their trajectory is classical. Here we propose a second level of quantisation where both the information and its propagation in spacetime is treated quantum mechanically. The framework is illustrated with a number of examples, showcasing some of the counterintuitive phenomena taking place when information travels simultaneously through multiple transmission lines.

Title: Computation of emotions
Time: 11:00am
Venue: Room 308, Chow Yei Ching Building, The University of Hong Kong
Speaker(s): Prof Peter Robinson
Remark(s): Date:
May 16, 2019
Thursday
11:00 am
Venue:
Room 308 Chow Yei Ching Building
The University of Hong Kong
Peter Robinson
Professor of Computer Technology
University of Cambridge
Abstract:
The importance of emotional expression as part of human communication has been understood since the seventeenth century, and has been explored scientifically since Charles Darwin and others in the nineteenth century. Recent advances in Psychology have greatly improved our understanding of the role of affect in communication, perception, decision-making, attention and memory.
At the same time, advances in technology mean that it is becoming possible for machines to sense, analyse and express emotions. We can now consider how these advances relate to each other and how they can be brought together to influence future research in perception, attention, learning, memory, communication,decision-making and other applications.
This talk will survey recent advances in theories of emotion and affect, their embodiment in computational systems, the implications for general communications, and broader applications.The combination of new results in psychology with new techniques of computation on new technologies will enable new applications in commerce, education, entertainment, security, therapy and everydaylife. However, there are important issues of privacy and personal expression that must also be considered.
About the Speaker:
Peter Robinson is Professor of Computer Technology at the University of Cambridge, where he works on problems at the boundary between people and computers. This involves investigating new technologies to enhance communication between computers and their users, and new applications to exploit these technologies.
His recent work has included desk-size projected displays, emotionally intelligent interfaces and applications in semi-autonomous vehicles. This has led to broader explorations of what it means to be human in an age of increasingly human-like machines.
