Quantum Computing and Blockchain in Business

By: Arunkumar Krishnakumar

Overview of this book

Are quantum computing and Blockchain on a collision course or will they be the most important trends of this decade to disrupt industries and life as we know it? Fintech veteran and venture capitalist Arunkumar Krishnakumar cuts through the hype to bring us a first-hand look into how quantum computing and Blockchain together are redefining industries, including fintech, healthcare, and research. Through a series of interviews with domain experts, he also explores these technologies’ potential to transform national and global governance and policies – from how elections are conducted and how smart cities can be designed and optimized for the environment, to what cyberwarfare enabled by quantum cryptography might look like. In doing so, he also highlights challenges that these technologies have to overcome to go mainstream. Quantum Computing and Blockchain in Business explores the potential changes that quantum computing and Blockchain might bring about in the real world. After expanding on the key concepts and techniques, such as applied cryptography, qubits, and digital annealing, that underpin quantum computing and Blockchain, the book dives into how major industries will be impacted by these technologies. Lastly, we consider how the two technologies may come together in a complimentary way.

Quantum-Safe Blockchain

The thesis of this book revolves around exploring two technologies: quantum computing and Blockchain. I have touched upon the key concepts and the history of these two technologies. There were a few interviews and industry-focused chapters where I brought to light the practical applications of these technologies. This was to establish that, despite several challenges, these technologies have fundamental use cases.

We have established that these two technologies are here to stay. They may go through winters, where their relevance may be challenged. Yet, the most impactful technologies weather such storms and resurface as soon as they become relevant. Technologies could see low points due to limitations or a lack of ecosystem maturity. In the case of Blockchain, we touched upon the trilemma that highlighted that the technology is yet to scale. For instance, a completely decentralized ledger often struggles to demonstrate the throughput that today&apos...
