In this undergraduate textbook, the author develops the quantum theory from first principles based on very simple experiments: a photon travelling through beam splitters to detectors, an electron moving through a Stern-Gerlach machine, and an atom emitting radiation. From the physical description of these experiments follows a natural mathematical description in terms of matrices and complex numbers. The first part of the book examines how experimental facts force us to let go of some deeply held preconceptions and develops this idea into a mathematical description of states, probabilities, observables, and time evolution using physical applications. The second part of the book explores more...
Based on eight extensive lectures selected from those given at the renowned Chris Engelbrecht Summer School in Theoretical Physics in South Africa, this text on the theoretical foundations of quantum information processing and communication covers an array of topics, including quantum probabilities, open systems, and non-Markovian dynamics and decoherence. It also addresses quantum information and relativity as well as testing quantum mechanics in high energy physics. Because these self-contained lectures discuss topics not typically covered in advanced undergraduate courses, they are ideal for post-graduate students entering this field of research. Some of the lectures are written at a more introductory level while others are presented as tutorials that survey recent developments and results in various subfields.

Explores the experiences of transnational migrant families from Africa, including flows into and out of South Africa, and how technology is used to maintain kinship and duties of care from afar.
The apartheid era in South Africa lasted more than 40 years. It was marked by political repression and the attempt to create a homogeneous "white South Africa", which meant excluding the non-white majority population. The establishment and maintenance of white supremacy in South Africa by colonialism and, since 1948, grand apartheid was not only the result of racist regulations and laws, but also followed a "scientific" logic to justify the resettlement and expulsion of South African blacks.The history of South Africa from 1948 to 1994 can also be seen as the history of a major society-spanning project; an attempt to build a "modern" state on the basis of racial segregation. This work investigates the factors that make it possible to stabilize a policy based on virtually impossible prerequisites over four decades: Ethnic categorization, territorial planning and "environmental protection measures".
These songlines’sing' into history the personal story of Action Learning and Research (ALAR) by an ALAR founder, Ortrun Zuber-Skerritt. Revealed through a collection of interviews conducted by scholars from six countries, these engaging, informative, intimate stories record her ALAR journey to document history and, more importantly, to help develop skills and innovation in workplace/community and lifelong learning for everyone, including the disadvantaged and poorest. Reviewers comments: This book is a must read for action researchers of all stripes and experience levels. Ortrun Zuber-Skerritt, a principal architect of ALAR who has pushed the boundaries of AR conceptually and methodologically, has now created a unique book built out of orchestrated interviews that provide us with much insight into who she is, why and how to learn from her, and invitation to collaborate in further developing our practice for the benefit of everyone.

"The magnitudes, nature, causes, and consequences of population movements between rural and urban sectors of developing countries are examined. The prior literature is reviewed, proving limited in key dimensions. Evidence is presented from a new database encompassing nationally representative data on seventy-five developing countries. Several measures of migration propensities are derived for the separate countries. The situation in each country is documented, both in historical context and following the time of enumeration. Rural-urban migrants enjoy major gains; those who do not move forego substantial, potential gains. Barriers to migrating are very real for disadvantaged groups. Migratio...
A thorough exposition of quantum computing and the underlying concepts of quantum physics, with explanations of the relevant mathematics and numerous examples. The combination of two of the twentieth century's most influential and revolutionary scientific theories, information theory and quantum mechanics, gave rise to a radically new view of computing and information. Quantum information processing explores the implications of using quantum mechanics instead of classical mechanics to model information and its processing. Quantum computing is not about changing the physical substrate on which computation is done from classical to quantum but about changing the notion of computation itself, a...
