A quantum computer works in a totally different way from a classical computer. Quantum bits or 'qubits' can exist in a superposition state of both zero and one simultaneously. This means that a set of two qubits can be in a superposition of four states, which therefore require four numbers to uniquely identify the state. So the amount of information stored in N qubits is two to the power of N classical bits.

Introduction:
RNS is a subfield of finite field arithmetic.
It is considered a carry-free system, which is used in cryptography.
Very suitable to be used in applications like DSP, Image Processing, FIR & IIR filters.
Thus, over 35 years RNS has received major attention in such applications that needs a high degree of concurrency.
Attractive for research due to its characteristics of error detection and correction (fault tolerant), modularity and embedded parallelism.

Title: Renyi's Information Measures and Augustin's Proof of The Sphere Packing Bound
Abstract: Information transmission problems are usually posed on models with finite sample spaces, such as the discrete product channels (DPCs), or on models with a specific noise structure, such as the Gaussian or Poisson models. Although such an approach is plausible, if not necessary, when analyzing a given information transmission problem for the first time, the analysis of the problem on abstract models, subsuming these special cases, is necessary in order to gain a more complete and fundamental understanding of the problem. Furthermore, such an analysis is likely to point out more fundamental observations that may or may not be salient in the analysis of the problem on more specific models.
The sphere packing bound (SPB), establishing the optimality of the list decoding variant of Gallager's inner bound, is a case in point. The standard proofs of the SPB are either for specific models, such as Gaussian or Poisson channels or for stationary product channels with finite input sets. Augustin's proofs of the SPB are exceptional in this regard because they establish the SPB for rather general abstract models. Furthermore, unlike previous proofs of the SPB, Augustin's proofs don't assume the channels to be stationary.** In this presentation, we use Renyi's information measures to derive the SPB with Augustin's method. In the first part of the presentation we review Renyi's information measures and point out some recent developments. In the second part of the presentation, we derive the SPB for product channels using Augustin's method and briefly discuss the derivation of SPB for the memoryless channels. In the last part of the presentation, we discuss possible applications of Augustin's method in other information transmission problems and point out new directions for abstract formulations of the information transmission problems.
**Ebert's proof of the SPB for Gaussian channels is the only previous proof that works for non-stationary channels.

Presented by Nigel P. Smart
ABSTRACT
Multi-Party Computation (MPC) allows, in theory, a set of parties to compute any function on their secret input without revealing anything bar the output of the function. For many years this has been a restricted to a theoretical tool in cryptography. However, in the past five years amazing strides have been made in turning theory into practice. In this talk I will present the latest, practical, protocol called SPDZ (Speedz), which achieves much of its performance advantage from the use of Fully Homomorphic Encryption as a sub-procedure. No prior knowledge of MPC will be assumed.

Daniel Lidar visited the Quantum AI Lab at Google LA to give a talk: "Quantum Information Processing: Are We There Yet?" This talk took place on January 22, 2015.
Abstract:
Quantum information processing holds great promise, yet large-scale, general purpose quantum computers capable of solving hard problems are not yet available despite 20+ years of immense effort. In this talk I will describe some of this promise and effort, as well as the obstacles and ideas for overcoming them using error correction techniques. I will focus on a special purpose quantum information processor called a quantum annealer, designed to speed up the solution to tough optimization problems. In October 2011 USC and Lockheed-Martin jointly founded a quantum computing center housing a commercial quantum annealer built by the Canadian company D-Wave Systems. A similar device is operated by NASA and Google. These processors use superconducting flux qubits to minimize the energy of classical spin-glass models with as many spins as qubits, an NP-hard problem with numerous applications. There has been much controversy surrounding the D-Wave processors, questioning whether they offer any advantage over classical computing. I will survey the recent work we have done to benchmark the processors against highly optimized classical algorithms, to test for quantum effects, and to perform error correction.

Agenda:
0:45 Intro
Lee Barford's job is to help to guide Keysight into the quantum computing industry and enable quantum computing experts
2:00 Why is quantum computing/a quantum computer important?
Clock rates for digital processors stopped getting faster around 2006 because of excessive heat
The processor manufacturers realized they needed more processor parallelism
Graphics processor units (GPUs) can be used as vector and matrix computational machines
Bitcoin utilizes this method.
6:00 What does the development of quantum computing and quantum computers mean for the future?
Gates being made with feature size of the digital transistor that have an effective gate length of down to 7 nm
Now we're pushing below 5 nm, and there are not many unit cells of silicon left in the layer. (one unit cell of silicon is 0.5 nanometer)
The Heisenberg uncertainty principle comes into play at this point because there are few enough atoms that quantum mechanical effects will disturb electronics.
These quantum mechanical effects include a superposition of states (Schrodinger's cat) and low error tolerance.
10:20 When will Moore's law fail?
Quantum computing and quantum computers are one way of moving the computing industry past this barrier by taking advantage of quantum effects - engineering with them - to build a quantum computer that will do certain tasks much faster than today's computers.
15:20 Questions for future episodes:
What sort of technology does it take to make a quantum computer?
Where are current experiments probing?
Why are people funding quantum computing research and the building of quantum computers?
What problems are quantum computing (and quantum computers) working to solve?
17:30 Using quantum effects
Quantum computers probably won't be used in consumer devices because it currently requires a very low temperature and/or a vacuum.
18:00 The quantum computer's fundamental storage unit is a qubit (quantum bit). It can be in states 1 or 0 with some finite probability
19:00
You can set up a quantum register to store multiple potential qubits, and when read out, have an identical probability to be either of these numbers. A quantum register can store multiple states at once, but only one register value can be read out of the quantum register.
21:00 How do you get the desired value out of a quantum register? You do as much of the computation ahead of time and then read the quantum computers quantum register.
It works because the answer is either such a high probability to be correct that you don't need to check it, or it is very easy to double check if the answer is correct.
21:00 How do you get the desired value out of a quantum register? You do as much of the computation ahead of time and then read the quantum computers quantum register.
22:30 Quantum computers are good at factoring very large numbers (breaking RSA in cryptography)

Quantum computers exploit the bizarre features of quantum mechanics to perform tasks that are impossible using conventional means. Sending instantaneous messages across long distances or quickly computing over ungodly amounts of data are just two possibilities that arise if we can design computers to exploit quantum uncertainty, entanglement, and measurement.
In this SFI Community Lecture, scientist Christopher Monroe describes the architecture of a quantum computer based on individual atoms, suspended and isolated with electric fields, and individually addressed with laser beams. This leading physical representation of a quantum computer has allowed demonstrations of small algorithms and emulations of hard quantum problems with more than 50 quantum bits. While this system can solve some esoteric tasks that cannot be accomplished in conventional devices, it remains a great challenge to build a quantum computer big enough to be useful for society. But the good news is that we don’t see any fundamental limits to scaling atomic quantum computers, and Monroe speculates as to how this might happen.
Christopher Monroe is a leading atomic physicist and quantum information scientist. He demonstrated the first quantum gate realized in any system at the National Institute of Standards and Technology (NIST) in the 1990s, and at University of Michigan and University of Maryland he discovered new ways to scale trapped ion qubits and simplify their control with semiconductor chip traps, simplified lasers, and photonic interfaces for long-distance entanglement. He received the American Physical Society I.I. Rabi Prize and the Arthur Schawlow Laser Science Prize, and has been elected into the National Academy of Sciences. He is Co-Founder and Chief Scientist at IonQ in College Park, MD.

Last year we showcased the incredible potential of CMOS when UltraCMOS® technology uses Intelligent Integration to provide the combination of reliability, smaller footprint, improved performance, greater system capability, and flexibility.
We demonstrated this potential by releasing the world’s first RF switch to operate at zero Hertz, replacing mechanical relays while integrating Analog, digital, and rf functions on a single die in order to enable features such as Analog DC-offset voltage tracking, digital logic control, and high performance rf switching.
Later we released our Monolithic Phase & Amplitude Controller, a single-chip, digitally-controlled solution used to optimize the performance of a Doherty power amplifier architecture. A single device which incorporates maximum phase and amplitude tuning flexibility for the carrier and peaking path with an integrated 90 degree splitter.
And now we are extending our phase and amplitude control capability into the microwave domain for Analog signal processing. Using intelligent integration, UltraCMOS RFICs provide a clear advantage to applications such as Wireless Infrastructure, 5G, Beamforming, Interference Cancellation, and commercial SAR applications such as weather radar, air traffic control, and phased array antenna for satellites. For example, next generation cellular systems will rely more on beamforming antennas to improve data rates and provide users with better quality of service (pause) or QOS. These antennas require advanced signal processing capabilities in order to accurately steer multiple signals simultaneously.
Leveraging the phase and amplitude control capability we’ve successfully developed for our MPAC product, we’re able to provide the phase and amplitude accuracy to enable fast, reconfigurable antennas for the next generation 5G solutions. Key to achieving the desired performance are intelligent arrays. In each antenna, the phase and amplitude of the signal can be independently and accurately controlled.
Let’s take a look at a typical beamforming example using signals received from a wireless transmitter. With increased accuracy, resolution, and speed of reconfiguration, intelligent arrays can be further optimized for their overall performance – whether it be the fundamental beam pattern or reducing unwanted interferers, either through interference nulling during the receive function or through better side-lobe suppression during transmission. When the phase accuracy and resolution of the array is low the directionality of the beam is also low. Increasing the phase accuracy and resolution increases the directionality and the ability to focus the signal at a specific handset. Further fine tuning the phase relationships of all the elements in an array can create nulling effects that can be leveraged to mitigate effects of interferers and help reduce the level of interference generated, improving overall signal quality and giving the user better QOS.
We’ve leveraged the success of the integrated phase and amplitude control of our MPAC products to start developing core chips that can utilize integrated digital capability to give the flexibility needed to tune gain and phase at fine resolution. Ideal for high density, compact arrays, such as the ones being developed for 5G, the UltraCMOS core chip uses intelligent integration to provide a flexible analog processing solution with digital programmability that works seamlessly together on a single, monolithic chip. Memory elements can be added to the core chip which allows pre-loading of configurations that can be automatically cycled at high speed. All of this without degradation in RF performance, especially linearity. And, UltraCMOS process consistency guarantees the reliability and repeatability of each device, resulting in a single-chip solution with the performance and versatility ideal for a wide-range of microwave applications.
This Configurability, Flexibility, Repeatability, Ease of Use, and Performance is only possible with UltraCMOS technology.
Intelligent Integration. UltraCMOS Technology.

Fingerprinting with Morph
Sun Tzu once stated, "Know your enemy and know yourself, and in a hundred battles you will never be defeated." By denying outsiders information about our systems and software, we make it more difficult to mount successful attacks.
There are a wealth of options for OS-fingerprinting today, evolving from basic TCP-flag mangling tools such as Queso, through the ICMP quirk-detection of the original Xprobe, and the packet timing analysis of RING, to today's suite of multiple techniques employed by nmap. The ultimate advantage in the OS-detection game lies with the defender, however, as it is they who control what packets are sent in response.
Morph is a BSD-licensed remote OS detection spoofing tool. It is portable and configurable, and will frustrate current state-of-the-art OS fingerprinting. This presentation will discuss the current techniques used for OS fingerprinting, and how to frustrate them. A newer version of Morph will be released with the talk, as a concrete example of the discussed techniques.

CERIAS Security Seminar at Purdue University
John Oritz, SRA International
John Oritz, SRA International
Steganography is a discipline of computer science whose aim is to conceal the existence of information. Steganography synergizes various technologies including data compression, digital signal processing, information theory, data networks, cryptography, coding theory, and the human audio and visual system. Strap on your seatbelt. I will present some key concepts of steganography, describe a number of basic and advanced spatial and transform domain techniques (with lots of pictures and sounds for the â��attention-challengedâ��), and demonstrate these techniques using custom steganography software. The demonstrations include a Least Significant Bit (LSB) technique, High-Capacity Hiding in Jpegs, and time modulation in audio.
John Ortiz is currently a senior computer engineering consultant for SRA International. In this position he researches information hiding techniques and steganography software, assesses the security and feasibility of advanced DoD security applications, examines and deobfuscates malware, and develops forensics tools. Prior to SRA, he spent 5 years at General Dynamics developing source code and network traffic analysis techniques and software.In a second role, Mr. Ortiz teaches a variety of computer science and electrical engineering courses at the University of Texas at San Antonio (UTSA). In particular, he developed and still teaches a Steganography course, which covers a broad spectrum of data hiding techniques in both the spatial and transform domains. For his course, Mr. Ortiz personally developed several steganographic programs for testing and analysis. Mr. Ortiz holds two masterâ��s degrees from the Air Force Institute of Technology, one in computer engineering and one in electrical engineering and a bachelorâ��s degree in electrical engineering from Rose-Hulman Institute of Technology.

In this talk I will cover two topics. I will present MPyC, an open-source Python framework for rapid prototyping of MPC protocols, which is being developed at TU Eindhoven. Also, I will present a new MPC protocol for securely solving a full-rank linear system over the rational numbers. More precisely, given a square full-rank matrix with integral coefficients, whose elements are secret-shared among multiple parties, the parties’ goal is to compute the inverse (over Q) in secret-shared form, without leaking any information. Finally I will demonstrate the usefulness of MPyC in practice, by means of explaining step-by-step the MPyC-implementation our new protocol for secure linear algebra.

ABSTRACT
Neurocomputational models provide fundamental insights towards
understanding the human brain circuits for learning new associations
and organizing our world into appropriate categories. In this talk I
will review the information-processing functions of four interacting
brain systems for learning and categorization:
(1) the basal ganglia which incrementally adjusts choice behaviors using environmental
feedback about the consequences of our actions,
(2) the hippocampus which supports learning in other brain regions through the creation of
new stimulus representations (and, hence, new similarity
relationships) that reflect important statistical regularities in the
environment,
(3) the medial septum which works in a feedback-loop with
the hippocampus, using novelty-detection to alter the rate at which
stimulus representations are updated through experience,
(4) the frontal lobes which provide for selective attention and executive
control of learning and memory.
The computational models to be described have been evaluated through a variety of empirical
methodoligies including human functional brain imaging, studies of
patients with localized brain damage due to injury or early-stage
neurodegenerative diseases, behavioral genetic studies of
naturally-occuring individual variability, as well as comparative
lesion and genetic studies with rodents. Our applications of these
models to engineering and computer science including automated anomaly
detection systems for mechanical fault diagnosis on US Navy
helicopters and submarines as well more recent contributions to the
DoD's DARPA program for Biologically Inspired Cognitive Architectures
(BICA).

The 50-year reign of Moore’s Law, which delivered a billion-fold increase in transistors per chip, is finally over. Given that transistors are no longer getting much better, that the power budgets of microprocessors are not increasing, and that we’ve already replaced the single power-hungry processor with several energy-efficient ones, the only path to improve energy-performance-cost is specialized hardware. Microprocessors of the future will include special-purpose processors that do one class of computation much better than general-purpose processors. Accelerators for deep neural networks are but one of many potential targets. Panelists will discuss what old doors this seismic change will close and what new doors it will open.

New Era in Distributed Computing with Blockchains and Databases
Abstract
A new era is emerging in the world of distributed computing with the growing popularity of blockchains (shared, replicated and distributed ledgers) and the associated databases as a way of integrating inter-organizational work. Originally, the concept of a distributed ledger was invented as the underlying technology of the cryptocurrency Bitcoin. But the adoption and further adaptation of it for use in the commercial or permissioned environments is what is of utmost interest to me and hence will be the focus of this keynote. Computer companies like IBM and Microsoft, and many key players in different vertical industry segments, have recognized the applicability of blockchains in environments other than cryptocurrencies. IBM did some pioneering work by architecting and implementing Fabric and then open sourcing it. Now Fabric is being enhanced via the Hyperledger Consortium as part of The Linux Foundation. A few of the other efforts include Enterprise Ethereum, R3 Corda, and BigchainDB.
While there is no standard in the blockchain space currently, all the ongoing efforts involve some combination of database, transaction, encryption, consensus, and other distributed systems technologies. Some of the application areas in which blockchain pilots are being carried out are: smart contracts, supply chain management, know your customer, derivatives processing, and provenance management. In this talk, I will survey some of the ongoing blockchain projects with respect to their architectures in general and their approaches to some specific technical areas. I will focus on how the functionality of traditional and modern data stores are being utilized or not utilized in the different blockchain projects. I will also distinguish how traditional distributed database management systems have handled replication and how blockchain systems do it. Since most of the blockchain efforts are still in a nascent state, the time is right for database and other distributed systems researchers and practitioners to get more deeply involved to focus on the numerous open problems.
This talk was delivered as the opening keynote at the 37th IEEE International Conference on Distributed Computing Systems (ICDCS) in Atlanta (USA) on 6 June 2017. Extensive blockchain related collateral could be found at bit.ly/CMbcDB.
Bio
Dr. C. Mohan has been an IBM researcher for 36 years in the database area, impacting numerous IBM and non-IBM products, the research and academic communities, and standards, especially with his invention of the ARIES family of database locking and recovery algorithms, and the Presumed Abort commit protocol.

A Google TechTalk, June 28, 2016, presented by Yu Chen (Google)
ABSTRACT: Quantum annealer, constructed from an array of coupled flux qubits, represents an analog approach to build a quantum computer. In Quantum A.I. Lab, we are working on building an enhanced-performance quantum annealer - quantum annealer v2.0. We introduce the "fluxmon" flux qubit as the building block of quantum annealer v2.0. With the capacitance and inductance provided by a coplanar waveguide, the fluxmon qubit design balances between coherence and coupling. Utilizing a microwave control and readout, we were able to characterize single-qubit performance and discovered that the qubit decoherence is dominated by 1/f flux noise over a wide range of frequencies. Meanwhile, with the linear inductance distributed over a macroscopic length scale, we discuss that the fluxmon design allows for GHz-scale coupling for multiple qubits, suitable for highly connected annealer architectures.
