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

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.

Can I download the code files for Early Access titles? Chevron down icon Chevron up icon

We try to ensure that all books in Early Access have code available to use, download, and fork on GitHub. This helps us be more agile in the development of the book, and helps keep the often changing code base of new versions and new technologies as up to date as possible. Unfortunately, however, there will be rare cases when it is not possible for us to have downloadable code samples available until publication.

When we publish the book, the code files will also be available to download from the Packt website.

How accurate is the publication date? Chevron down icon Chevron up icon

The publication date is as accurate as we can be at any point in the project. Unfortunately, delays can happen. Often those delays are out of our control, such as changes to the technology code base or delays in the tech release. We do our best to give you an accurate estimate of the publication date at any given time, and as more chapters are delivered, the more accurate the delivery date will become.
