Quantum Supremacy: How Quantum Computers will Unlock the Mysteries of Science – and Address Humanity’s Biggest Challenges

Product Information

The runaway success of the microchip processor may be reaching its end. Running up against the physical constraints of smaller and smaller sizes, traditional silicon chips are not likely to prove useful in solving humanity’s greatest challenges, from climate change, to global starvation, to incurable diseases. But the quantum computer, which harnesses the power and complexity of the atomic realm, already promises to be every bit as revolutionary as the transistor and microchip once were. Its unprecedented gains in computing power herald advancements that could change every aspect of our daily lives.

Quantum Supremacy is definitely the best book on quantum computing, its expected integration to AI, and the startling results of this combination. There’s hope, though. Mother nature achieves coherence at regular temperatures in a little process called photosynthesis. So scientists are studying how coherence is achieved in nature in the hope of finding a way to recreate the process in a computer.Me: Yes, but how is the computation performed with qubits? Why is it so powerful? Why do particles have to be entangled? This book has a whole lot of speculation, a lot of 'mays' and 'mights'. 'Might' is used 178 times and 'may' a whopping 304. Quantum calculations could also direct the course of gene-editing therapies with the potential of heading off diseases before they arise — an application that raises hopes as well as ethical concerns.

Why is that? In contrast to the rigid one-or-zero approach that serves as the foundation of classical computing, quantum computers would take advantage of the fact that quantum bits — better known as qubits — can represent multiple states when information is processed. Quantum computing could change our perspective on the cosmos.

Moore’s Law, first postulated in 1965, suggests that the number of transistors that can be built into a microchip doubles every 18 months. Effectively, that means computer power also doubles every 18 months. But if we continue primarily using silicon, this law will stop being true in the very near future.Me, after a long while: This has been quite interesting. But I would still like to understand how quantum computation-- If the reader is a bit suspicious of both the future of computing and AI and how it will affect our lives, Kaku’s effort is heads above the numerous books I’ve read on quantum computing work, separately, and the great potential when working together. Kaku produces great insights and explanations of how they work together. As a physicist, his investigation clears up many of the challenging technical issues that are glossed over by non-scientist authors. This is a huge differentiator. On November 16 of that same year, the IBM Eagle was revealed which beat them both with 127 qubits. A year later IBM launched Osprey at 433 qubits.

No device came close to the technical advancement of the Antikythera device – let alone built on it – until the 1800s. It was then that Charles Babbage invented the first digital computer. Ada Lovelace, daughter of Lord Byron, figured out how to feed the computer information to get it to perform complicated mathematical tasks that were essential in industries such as construction or navigation. She was essentially the first programmer. Simulation is the goal of quantum computing. When we can simulate the world around us down to the quantum level, we can begin to analyze some of the many problems that have plagued us since the beginning of time. Computer scientists might take issue with Kaku’s digital doomsaying — but there’s little doubt that quantum computers will transform the field as much as artificial intelligence is transforming it today.It's about what quantum computers "might" be able to do in the future if we can build sophisticated enough ones to solve practical problems that require far too much data for digital computers.

stars -- 3 stars is "liked it", and in this case I can't force myself to say I did. On the other hand, it had plenty of interesting information, some of which was new to me. Thanks to all of these inventions and discoveries, we understand the pieces and processes needed to produce the energy that sustains life. But there are still many obstacles to overcome. Just like Haber’s crude process for nitrogen-fixing, many of our attempts at coming up with clean energy are actually sourced through unsustainable means, and our efforts at discovery are still done largely by trial and error.

Chemists who do not use quantum computers to model chemical reactions will go bankrupt,” he says. “They’ll be out of a job. They’ll be replaced by chemists who do use quantum computers. This means all medicine. All medicine can eventually be reduced to a quantum computer.” Earth is warming up as a result of human behavior. This warming is creating a variety of problems. One of those is the release of the greenhouse gas methane due to the melting of polar ice caps. As it’s released, it contributes to yet more global warming. How do we find new drugs today? Trial and error,” Kaku says. “We have thousands of Petri dishes with chemicals in them. We tediously see whether or not they have any antibiotic properties. Why not do that in the memory of a quantum computer?”
