Understanding Quantum Technologies 2022

Understanding Quantum Technologies 2022 is a creative-commons ebook that provides a unique 360 degrees overview of quantum technologies from science and technology to geopolitical and societal issues. It covers quantum physics history, quantum physics 101, gate-based quantum computing, quantum computing engineering (including quantum error corrections and quantum computing energetics), quantum computing hardware (all qubit types, including quantum annealing and quantum simulation paradigms, history, science, research, implementation and vendors), quantum enabling technologies (cryogenics, control electronics, photonics, components fabs, raw materials), quantum computing algorithms, software development tools and use cases, unconventional computing (potential alternatives to quantum and classical computing), quantum telecommunications and cryptography, quantum sensing, quantum technologies around the world, quantum technologies societal impact and even quantum fake sciences. The main audience are computer science engineers, developers and IT specialists as well as quantum scientists and students who want to acquire a global view of how quantum technologies work, and particularly quantum computing. This version is an extensive update to the 2021 edition published in October 2021.Comment: 1132 pages, 920 figures, Letter forma

On 'a continuum with expansion' : UK-US intelligence relations & wider reflections on international intelligence liaison

Since 9/11, intelligence liaison has increased exponentially. Yet, both in international affairs and within the academic fields of international relations (IR) and intelligence studies, the phenomenon of intelligence liaison remains under-researched and under-theorised. Moreover, intelligence studies remain remarkably disconnected from IR. Accordingly, this study attempts to advance a timely understanding of both international intelligence liaison generally, and UK-US intelligence liaison specifically, in a contemporary context. Methodologically, this is accomplished through conducting a qualitative analysis of UK-US intelligence liaison focussed on two ‘critical’ and ‘intensive’ case studies. These represent the key issues over which the UK and US have liaised, namely counter-terrorism and weapons of mass destruction (WMD) non-/counter-proliferation. In practical terms, the ‘rise’ of intelligence liaison can be substantially explained. However, the phenomenon itself can only be ‘theorised’ so far. Intelligence is, by its very nature, a fragmented subject. Accordingly, cascades of complexities increasingly enter, especially at the lower/micro levels of analysis - where the details and specifics concerning particular sources and operations matter further. Therefore, intelligence liaison effectively represents the concept of ‘complex co-existence plurality’ in action. This is both at and across all its different, yet closely interrelated, levels of analysis, and also when broken down into eight systemic variables or attributes. Notwithstanding this complexity, wider conclusions can be drawn, allowing this thesis to advance the proposition that we are now witnessing the globalisation of intelligence. Overall, this trend is facilitated through the developments occurring in a web of overlapping international intelligence liaison arrangements, which collectively span the globe. Reflective of a continuously evolving attempt for ‘optimum outreach’, these intraliaison developments include: firstly, the establishing of frameworks and defining of operational parameters for the intelligence liaison arrangements, and then their subsequent consolidation (or normalisation) and optimisation over time. These wider trends are simultaneously observable in the microcosm of UK-US intelligence liaison relations, which are also on ‘a continuum with expansion’ as the UK and US remain broadly exemplary ‘friends and allies’

Spying on chaos-based cryptosystems with reservoir computing

International audienceReservoir computing is a machine learning approach to designing artificial neural networks. Despite the significant simplification of the training process, the performance of such systems is comparable to other digital algorithms on a series of benchmark tasks. Recent investigations have demonstrated the possibility of performing long-horizon predictions of chaotic systems using reservoir computing. In this work we show that a trained reservoir computer can reproduce sufficiently well the properties a chaotic system, hence allowing full synchronisation. We illustrate this behaviour on the Mackey-Glass and Lorenz systems. Furthermore, we show that a reservoir computer can be used to crack chaos-based cryptographic protocols and illustrate this on two encryption schemes. © 2018 IEEE

Tematski zbornik radova međunarodnog značaja. Tom 3 / Međunarodni naučni skup “Dani Arčibalda Rajsa”, Beograd, 10-11. mart 2016.

In front of you is the Thematic Collection of Papers presented at the International Scientific Conference “Archibald Reiss Days”, which was organized by the Academy of Criminalistic and Police Studies in Belgrade, in co-operation with the Ministry of Interior and the Ministry of Education, Science and Technological Development of the Republic of Serbia, National Police University of China, Lviv State University of Internal Affairs, Volgograd Academy of the Russian Internal Affairs Ministry, Faculty of Security in Skopje, Faculty of Criminal Justice and Security in Ljubljana, Police Academy “Alexandru Ioan Cuza“ in Bucharest, Academy of Police Force in Bratislava and Police College in Banjaluka, and held at the Academy of Criminalistic and Police Studies, on 10 and 11 March 2016. The International Scientific Conference “Archibald Reiss Days” is organized for the sixth time in a row, in memory of the founder and director of the first modern higher police school in Serbia, Rodolphe Archibald Reiss, PhD, after whom the Conference was named. The Thematic Collection of Papers contains 165 papers written by eminent scholars in the field of law, security, criminalistics, police studies, forensics, informatics, as well as by members of national security system participating in education of the police, army and other security services from Belarus, Bosnia and Herzegovina, Bulgaria, China, Croatia, Greece, Hungary, Macedonia, Montenegro, Romania, Russian Federation, Serbia, Slovakia, Slovenia, Spain, Switzerland, Turkey, Ukraine and United Kingdom. Each paper has been double-blind peer reviewed by two reviewers, international experts competent for the field to which the paper is related, and the Thematic Conference Proceedings in whole has been reviewed by five competent international reviewers. The papers published in the Thematic Collection of Papers contain the overview of contemporary trends in the development of police education system, development of the police and contemporary security, criminalistic and forensic concepts. Furthermore, they provide us with the analysis of the rule of law activities in crime suppression, situation and trends in the above-mentioned fields, as well as suggestions on how to systematically deal with these issues. The Collection of Papers represents a significant contribution to the existing fund of scientific and expert knowledge in the field of criminalistic, security, penal and legal theory and practice. Publication of this Collection contributes to improving of mutual cooperation betw
