Quantum Cryptography and Secure Communications: An Applied Approach explores the fundamentals of quantum computing, quantum cryptography, and secure communication, and offers an insight into quantum key distribution (QKD) and Post-Quantum Cryptography (PQC). The book looks at QKD protocols, techniques and algorithms, such as BB84, E91 and SARG04, and how secure communication uses quantum physics to construct a cryptographic protocol which allows two parties to generate a shared secret key that is known only to them. The applied approach of the book examines recent implementations of quantum cryptography for secure communication among different industry vertices, discusses algorithms which are quantum resistant, such as lattice based and code based algorithms, and considers how secure quantum computing applications addresses societal challenges such as sustainability, as well as the crucial role played by simulations. Quantum Cryptography and Secure Communications finishes with a study of current research trends and uses cases within quantum cryptography to provide a structured learning process that intertwines theory with practical applications, to make quantum cryptography more approachable and relevant.Offers an overview of the fields of quantum cryptography and secure communicationsCombines quantum key distribution (QKD) and post-quantum cryptography techniquesProvides examples and case studies to ground the theory in practiceConsiders how quantum computing applications can address sustainability and societal challenges

This book explores the risk-return paradox in portfolio selection by incorporating multi-objective criteria. Empirical research is presented on the development of alternate portfolio models and their relative performance in the risk/return framework to provide solutions to multi-objective optimization. Next to outlining techniques for undertaking individual investor’s profiling and portfolio programming, it also offers a new and practical approach for multi-objective portfolio optimization. This book will be of interest to Foreign Institutional Investors (FIIs), Mutual Funds, investors, and researchers and students in the field.

This book explores the rapidly evolving Metaverse, where digital and physical realities merge to create immersive interactions and transactions. As virtual real estate and digital assets gain traction, investors increasingly view them as a new asset class, akin to traditional real estate or collectibles. Blockchain technology underpins this transformation, ensuring secure transactions through decentralized and transparent systems. Non-fungible tokens (NFTs) play a crucial role in establishing ownership, enabling value exchange, and preserving intellectual property within virtual economies.The book presents the financial and legal dimensions of Metaverse investments, covering blockchain, Web3, cryptocurrencies, and NFTs. It examines how digital property markets operate, with investors purchasing, selling, and monetizing virtual land and assets in platforms like The Sandbox and Decentraland. Key factors such as virtual location, user traffic, and economic activity influence the valuation of these assets.Beyond investment opportunities, the book highlights the broader economic impact of the Metaverse, including monetization avenues for creators, developers, and businesses. It explains how smart contracts and financial assurance mechanisms enhance trust and security in virtual transactions. Additionally, it addresses the evolving legal frameworks for digital intellectual property rights, ensuring regulatory clarity and integrity.This book is essential for investors, legal scholars, financial analysts, policymakers, and tech enthusiasts looking to understand the intersection of digital assets, blockchain, and virtual economies. By providing a comprehensive analysis of Metaverse finance, it equips readers with the insights needed to navigate this transformative digital landscape.
