Quantum optics, i.e. the interaction of individual photons with matter, began with the discoveries of Planck and Einstein, but in recent years it has expanded beyond pure physics to become an important driving force for technological innovation. This book serves the broader readership growing out of this development by starting with an elementary description of the underlying physics and then building up a more advanced treatment. The reader is led from the quantum theory of the simple harmonic oscillator to the application of entangled states to quantum information processing. An equally important feature of the text is a strong emphasis on experimental methods. Primary photon detection, heterodyne and homodyne techniques, spontaneous down-conversion, and quantum tomography are discussed, together with important experiments. These experimental and theoretical considerations come together in the chapters describing quantum cryptography, quantum communications, and quantum computing.

This handbook maps and analyzes cross-sector (public–corporate–social–community–faith) governance theories, models, and practices as they are evolving in a digital world. It studies human, cultural, societal, institutional interactions and challenges in a digitally enabled world, especially in the context of post-crisis resilience and agility. Every global crisis forces societies and nations to realign while addressing deeper structural and cultural issues in governance. The Covid-19 pandemic has necessitated swift local-to-global governance responses for timely digital innovations for health crisis interventions, economic recovery, and societal equity. While every nation-state is developing global pandemic responses in a digitally enabled world, the deeper crisis of human, institutional, and societal governance deficit is also evident. This handbook documents digital governance innovations that enhance stakeholder engagement and inclusion for resilient, accountable, and effective governance across sectors. This volume reflects on a range of theoretical frameworks adapted for understanding global and digital governance. It looks at international governance collaborations; corporate governance reform; education governance innovations; public sector and urban governance; health system governance, sustainability, and environmental governance; community and faith-based governance; and digital, cultural, and creativity governance. This book is unique, as it presents important work on post Covid-19 digital and democratic governance and brings together holistic—interdisciplinary and intersectoral— perspectives from the Global North and Global South, engaging the leading scholars, practitioners, businesses, and civil society. It will be of interest to multi-sector institutions and global audiences: governments, corporates, social sector institutions, digital entrepreneurs, students and researchers, academic professionals, policy-makers, public and private sector institutional leaders, and organizational and entrepreneurial innovators interested in the field of governance.
