Decoy State Quantum Key Distribution---The Best of Both Worlds
Wed, Mar 02, 2005 @ 11:00 AM - 12:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Dr. Hoi-Kwong Lo, University of TorontoAbstract: There has been much interest in quantum key distribution. Experimentally, quantum key distribution over 150 km of commercial Telecom fibers has been successfully performed. Commercial quantum cryptographic products are currently being marketed by two start-ups. The crucial issue in quantum key distribution is its security. Unfortunately, all recent experiments are, in principle, insecure due to real-life imperfections. Here, we propose a method that can for the first time make most of those experiments secure by using essentially the same hardware. Our method is to use decoy states to detect eavesdropping attacks. As a consequence, we have the best of both worlds---enjoying unconditional security guaranteed by the fundamental laws of physics and yet surpassing substantially even some of the best experimental performances reported in the literature.[Work done with Xiongfeng Ma and Kai Chen.]Bio: Hoi-Kwong Lo is currently an Associate Professor of the Center for Quantum Information and Quantum Control (CQIQC), at the Dept. of ECE and Dept. of Physics of the University of Toronto. He received his Ph.D. in Physics from Caltech in 1994. After spending two years at the Institute for Advanced Study (IAS), Princeton, he joined Hewlett-Packard Labs, Bristol UK in 1996 and became a Senior Member of Technical Staff there in 1997. From 1999 to 2002, he was the Senior VP, R&D and Chief Scientist of MagiQ Technologies, Inc., a firm that has recently been chosen as a top ten company to watch by IEEE Spectrum. Hoi-Kwong Lo was among the first to prove the impossibility of quantum bit commitment and the security of quantum key distribution. His work has been widely reported in scientific press including "Science" and "Science News". His recent work on decoy state QKD (the subject of the present talk) was highlighted recently in a "News Scientists" article. He is a Founding Managing Editor of the journal QIC, which is a leading journal in the field. In 2003, he won a number of honors including Canada Research Chair, Ontario Distinguished Researcher, Premier's Research Excellence Award and Outstanding Young Researcher Award by the Overseas Chinese Physics Association.Host: Dr. Igor Devetak, x.09264, devetak@usc.edu

MULTIPLAYER GAMES AND ADAPTIVE CONVERGENCE TO NASH EQUILIBRIA

Professor Jeff ShammaMechanical and Aerospace Engineering Department
University of California, Los AngelesConsider a scenario in which multiple decision makers repeatedly play a matrix game and adjust their strategies according to observations of each other's actions. The game is noncooperative in that each player may have its own objective/utility function, and these objectives are not shared among players. A central issue is whether player strategies will converge to a Nash equilibrium. Prior work shows how convergence to a Nash equilibrium in this setting may or may not occur. This talk presents new strategic update mechanisms that can lead to convergent
behavior in previously nonconvergent cases (such as the Shapley and Jordan counterexamples) through the use of fundamental feedback control concepts. The talk also discusses implications regarding evolutionary game theory and population dynamics.----------------------------------------------------------- BIOGRAPHY Jeff S.

"FPGA-BASED DATA-MINING ARCHITECTURES"Zachary BakerElectrical Engineering-SystemsAbstract:Recent advances in storage and data sensing have revolutionized our technological capability for collecting and storing data. The Apriori algorithm is a popular correlation-based data-mining kernel. However, it is a computationally expensive algorithm and the running times can stretch up to days for large databases, as database sizes can extend to Gigabytes. Through the use of a new extension to the systolic array architecture, time required for processing can be significantly reduced. Our array architecture implementation on a Xilinx Virtex-II Pro 100 provides a performance improvement that can be orders of magnitude faster than the state-of-the-art software implementations. The system is easily scalable and introduces an efficient ``systolic injection'' method for intelligently reporting unpredictably generated mid-array results to a controller without any chance of collision or excessive stalling.Bio:Zachary K.

"SOFTWARE DEFINED SIGNAL PROCESSING"Prof. Ryan KastnerUC, Santa BarbaraAbstract:The vision of ubiquitous connectivity is gradually becoming a reality with the development and deployment of cellular, Wi-Fi (802.11x) and even underwater wireless networks. However, many important challenges remain before true universal access is achieved. Among them is the development of hardware that can implement these increasingly complex communication protocols. Ideally, the hardware platform will provide a mechanism for multimode, multi-band, and multifunctional wireless communication. All the functions of this "software defined" communication device, except the front end of the receiver/transmitter (e.g. antenna and RF power amplifier), are implemented in changeable code. This requires an efficient and flexible high performance platform. The performance and flexibility of reconfigurable computing systems make them ideal platform for software defined signal processing. In order to realize a software-defined signal processing system, we must develop tools and methodologies to can automatically map communication protocols to hardware. In this talk, I will describe some of our research aimed at providing signal processing application designers with basic tools that allow them to quickly map their protocols into reconfigurable hardware. I will present a design flow from high level application specification to a bitstream that can be used to program a modern, high performance FPGA. Our design flow is unique in that it treats the FPGA as a two dimensional array of configurable data paths. As such, the distribution of the application data plays a large role in the performance of the application mapping. I will discuss our optimizations for partitioning data across the complex memory hierarchy seen in modern reconfigurable architectures. To motivate our design flow, I will discuss our recent work on implementing two signal processing applications on a high performance FPGA - radiolocation algorithms for RF (802.11x) and underwater acoustic modems.Bio:Ryan Kastner is currently an assistant professor in the Department of Electrical and Computer Engineering at the University of California, Santa Barbara. He received a PhD in Computer Science (2002) at UCLA, a masters degree in engineering (2000) and bachelor degrees (BS) in both electrical engineering and computer engineering (1999), all from Northwestern University. His current research interests lie in the realm of embedded systems, in particular reconfigurable computing, compilers and sensor networks. Professor Kastner has published close to 50 journal and conference papers, and is the author of the book, "Synthesis Techniques and Optimizations for Reconfigurable Systems" (with Majid Sarrafzadeh and Adam Kaplan), available from Kluwer Academic Publishing. He is a member of numerous conference technical committees including International Conference on Computer Aided Design (ICCAD), Design Automation Conference (DAC), International Conference on Computer Design (ICCD), Great Lakes Symposium on VLSI (GLSVLSI), the Engineering of Reconfigurable Systems and Algorithms (ERSA) and the IEEE International Symposium on Circuits and Systems (ISCAS). He serves on the editorial board for the Journal of Embedded Computing.Host: Prof. Viktor Prasanna, Ext. 04483

"DISTRIBUTION OF PATH DURATIONS IN MOBILE AD-HOC NETWORKS"Prof. Richard LaUniversity of MarylandAbstract:We study the distribution of path duration in multi-hop wireless networks. Sadagopon et al. have shown using simulation results that the distribution of path duration can be well approximated when the number of hops in the path is larger than 3-4. In this talk we will show using an analytical model that indeed as the number of hops along a path increases, the path duration distribution can be accurately approximated by an exponential distribution under a set of mild conditions. We consider two different cases: (i) link residual lives are independent, and (ii) link residual lives are not independent. In the latter case we assume that the dependency between two links goes away as the distance between them increases. Then, we develop an approximate model for computing the distribution of link duration under a Random Waypoint (RW) mobility model, and demonstrate that the path duration distribution converges to an exponential distribution with increasing number of hops. Simulation results obtained using ns-2 simulator are provided to validate our assumptions and analysis as well as the accuracy of our approximate model for RW mobility.** Refreshments will be served Host: Prof. Ahmed Helmy, x11329, helmy@usc.edu

DISTINGUISHED LECTURER SERIES: Assisted Capacities of Quantum Channels
Thu, Mar 24, 2005 @ 03:00 PM - 04:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
DR. CHARLES BENNETTIBM T.J. WatsonABSTRACT:Auxiliary resources such as shared randomness and feedback have no effect on the capacity of classical channels, but can have a dramatic effect on both the classical and quantum capacities of quantum channels. It has long been known that classical feedback can increase the quantum capacity of quantum channels, but recent results suggest that it can also increase their classical capacity. The quantum analog of shared randomness, namely sender:receiver entanglement, is the most powerful auxiliary resource, leading to assisted capacities that are both larger, and given by a simpler mathematical expressions, than other capacities. Joint work with Igor Devetak, Peter Shor, and John Smolin.BIO:Charles H. Bennett graduated from Croton-Harmon High School in 1960 and from Brandeis University, majoring in chemistry, in 1964. He received his PhD from Harvard in 1970 for molecular dynamics studies (computer simulation of molecular motion) under David Turnbull and Berni Alder. For the next two years he continued this research under the late Aneesur Rahman at Argonne Laboratory. Since coming to IBM Reseach in 1972, he has worked on various aspects of the relation between physics and information. In 1973, building on the work of IBM's Rolf Landauer, he showed that general-purpose computation can be performed by a logically and thermodynamically reversible apparatus, which can operate with arbitrarily little energy dissipation per step because it avoids throwing away information about past logical states; and in 1982 he proposed a reinterpretation of Maxwell's demon, attributing its inability to break the second law to the thermodynamic cost of destroying, rather than acquiring, information. In collaboration with Gilles Brassard of the University of Montreal he developed a practical system of quantum cryptography, allowing secure communication between parties who share no secret information initially, based on the uncertainty principle instead of usual computational assumptions such as the difficulty of factoring, and with the help of John Smolin built a working demonstration of it in 1989. Other research interests include algorithmic information theory, in which the concepts of information and randomness are developed in terms of the input/output relation of universal computers, and the analogous use of universal computers to define the intrinsic complexity or "logical depth" of a physical state as the time required by a universal computer to simulate the the evolution of the state from a random initial state. In 1983-5 as visiting professor of computer science at Boston University, he taught courses on cryptography and the physics of computation. In 1993 Bennett and Brassard, in collaboration with Claude Crepeau, Richard Jozsa, Asher Peres, and William Wootters, discovered "quantum teleportation," an effect in which the complete information in an unknown quantum state is decomposed into purely classical information and purely non-classical Einstein-Podolsky-Rosen (EPR) correlations, sent through two separate channels, and later reassembled in a new location to produce an exact replica of the original quantum state that was destroyed in the sending process. In 1995-7, working with Smolin, Wootters, IBM's David DiVincenzo, and other collaborators, he helped found the quantitative theory of entanglement and introduced several techniques for faithful transmission of classical and quantum information through noisy channels, part of the larger and recently very active field of quantum information and computation theory. More recently He is an IBM Fellow, a Fellow of the American Physical Society, and a member of the National Academy of Sciences.
