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.

The hype surrounding quantum networks

In the section discussing China's focus on quantum communication, we saw that they were able to pioneer quantum-encrypted communication channels that are secure from hackers. Quantum encryption is a good step forward. However, information flow on quantum networks is being hailed as the holy grail of secure communication.

Imagine an internet where nobody can eavesdrop on your messages. Imagine an internet where you can communicate and transact freely without having to worry about data security. That could be possible as qubits lose their states as soon as observed. Therefore, when there is a hacking attempt, the sender and the receiver of the message can identify it. The implications of this technology paradigm for communications in military and defense can hardly be underestimated.

A quantum network could be visualized as a network of three quantum devices that are 50 to 100 kilometers apart. China created the first quantum satellite...
