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.

Does quantum computing mean chaos?

So why is internet security, as it stands today, a ticking time bomb? Would there be chaos if quantum computing became mainstream, and what are the chances of that happening? These are the questions that have largely been troubling nation states worried about cyber warfare. CEOs of top banks and healthcare firms dealing with sensitive client data are also worried about data security.

Let's quickly look at where the quantum computing world is and why it might be a threat to global data security. In 1994, Peter Shor presented two quantum algorithms. One that could factor large prime numbers and another that could compute discrete logarithms in a finite field of prime order. The former could be a threat to the RSA method, and the latter would address elliptic curves.

Shor essentially showed that almost all public key encryption techniques we use today can be cracked using a quantum Fourier attack. He used quantum Fourier sampling to find the...
