Quantum Computing and Blockchain in Business

Quantum Computing – Key Discussion Points

At a recent event, I was asked a question on the kind of problems a quantum computer could solve that a classical computer cannot. The audience were also keen to understand why quantum computers were able to do things that classical computers have historically struggled with. A quantum computer could potentially model nature and the complexities that lie within. Classical computers are yet to scale to that extent as bits exist in two states. The ability of quantum systems to exist in superpositions allows them to deal with the problems of exponential. In order to understand how quantum computers can, in effect, leapfrog innovations in several industries, it is critical to understand the fundamental principles of quantum physics that underlie quantum computing.

Many of these principles of quantum physics have evolved over a century, and have a particular weirdness about them, as they are often counter-intuitive to minds...

Superposition

Superposition is one of the properties that differentiates a quantum computer from a classical computer. The qubits of a quantum computer can exist in 0s and 1s and linear combinations of both of these states. A quantum computer can achieve a special kind of superposition that allows for exponentially more logical states at once. This helps in solving problems such as factoring large numbers, which is typically hard for classical computers to solve. Classical computers are limited in terms of their ability to model the number of permutations and combinations that cryptography needs.

An example of the application of quantum computers in cryptography involves RSA encryption. RSA encryption involves two large prime numbers being multiplied to arrive at a larger number. The following examples should bring these challenges to life.

An exponential challenge

The story of the chessboard and rice brings to life the challenges in dealing with the exponential...

Entanglement – spooky action at a distance

The quantum property of entanglement was referred to by Einstein as Spooky action at a distance. Two particles in a system are entangled if one particle in a system cannot be described without taking the other part into consideration. In a quantum computer, qubits demonstrate this property. So, the probability of observing the configuration of one qubit will depend on the probability of observing the configuration of its entangled other half. This property of qubits exists in a quantum system, even when the entangled pair are separated by a good distance. This means, if one qubit spins in a clockwise direction, its entangled pair could spin in a counter-clockwise direction, even when miles apart.

Recently, scientists in China have demonstrated entanglement at a distance of up to 1,200 kilometres. Source: https://phys.org/news/2018-01-real-world-intercontinental-quantum-enabled-micius.html

This experiment was...

Conclusion

In order to understand the interviews in this book, and the key inferences from them, it is essential that this chapter is well understood by the reader. For the same reason, I have described the concepts of quantum computing using practical examples, with comparisons to classical computing equivalents. There are a few concepts of quantum computing that are hard to grasp without delving into the underlying physics (if not the math). In such cases, the simplification of the underlying concepts of physics in this chapter would help understand the weirdness in the behavior of microscopic elements that make up a quantum system. The simplified version may make a quantum scientist cringe, but I firmly believe that simplifying the narrative is critical for any technology to go mainstream.

Description

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.

This a comprehensive but easy to read exploration into some of the most complex technology subject matters. For novice and expert alike, this book offers so much. The exploration into business applications and the use cases that prove the need for this technology, is both practical and rewarding. And it’s something I feel will have an evergreen nature to it.

Many business leaders and software developers have heard about Quantum Computing and Blockchain, but not many understand what applications could be built and how these technologies could be used to explorer new business opportunities in Healthcare, Financial Services, Logistics, Climate and Elections.The "Quantum Computing and Blockchain in Business" gives a very good explanation of these two technologies in easy to understand language. The book includes many charts, graphs and images which help the reader to better understand the concepts being described. A nice touch is the link to download the colour images.The font size used is very readable which puts less strain on your eyes. If you are an old fashioned like me I prefer the physical, paper book instead of a tablet.There aren't many books written on the subject and I would recommend "Quantum Computing & Blockchain in Business" to anybody who would like to learn more about Quantum Computing and Blockchain.

This books explains very well what Blockchain and Quantum are and their main applications in businesses, as well as interviews with experts in both technologies. I liked that it connects what the technologies are with their projected use cases in a realistic manner, knowing that these are emergent technologies and there is always a tendency to create a hype. Points extra for treating this subject from a humble, realistic perspective. Great book!

Blockchain and quantum computing are poised to have significant impact across a host of industries. If you are a business leader, if you are an armchair futurist or technologist, or even if you are a science fiction writer who wants to get the science right, you should read this book. Not only does it go beyond the hype, it provides a solid historical perspective to help put these technologies in context. It also provides a sound technical explanation which does not require a PhD in physics to understand.In my role as a healthcare leader, I need to understand the technologies that are going to change our business. As a citizen of the world, it is also useful to understand the changes that may be occurring in other industries.For those that also are interested in how the world might change in the next decade or two, the digitization of our lives which has already been occurring lends itself well to the simultaneous advances in artificial intelligence/machine learning, blockchain, and quantum computing. This book provides a peek into what that future might look like.
