Quantum 2.0: The Weird Physics Driving a New Revolution in Technology
Quantum computers, quantum cryptography, and even quantum AI—a century after the discovery of an unexpected physical world, researchers are putting this puzzling science to work in dazzling new ways.
In this exhilarating and mind-bending book, renowned scientist and author Paul Davies offers readers a glimpse of how quantum physics has led to a quantum technology revolution. Quantum 2.0 reveals how today’s brightest minds are harnessing exotic states of matter that have no counterpart in everyday life. Specifically, all eyes are on entanglement, called “spooky” by Einstein, which links the activities of separated particles even across vast distances.
By manipulating these weird properties of atoms, electrons, and photons, scientists are driving the burgeoning field of “quantum information science,” featuring new tools such as quantum computers, quantum cryptography, and the quantum internet. In turn, their efforts have attracted billions of dollars in investments and triggered a frantic quantum arms race between nations. At the same time, theorists are taking a closer look at quantum systems themselves, which possess properties that defy intuition and shred everyday notions of reality. Davies explains how researchers, including himself, are wrestling with quantum theory to make sense of this realm, where ghostly quantum particles produce tiny forces in nanotechnology, cause black holes to evaporate, and may even contribute to the universe’s accelerating expansion. A trusted guide, Davies takes readers from the basic concepts to today’s cutting edge, inviting us all to glimpse the wonderland of quantum physics and its stunning implications.

Review of advance copy received from Netgalley
Quantum 2.0: The Weird Physics Driving a New Revolution in Technology by Paul Davies is a deeply ambitious exploration of the scientific principles shaping the next technological revolution. I requested this ARC out of professional and personal interest, as my background in cybersecurity closely intersects with the future implications of quantum computing—particularly in encryption, data security, and computational power.
Davies methodically traces the evolution of quantum mechanics, from its early theoretical foundations to the major breakthroughs that have positioned it at the forefront of modern science. He highlights key advances across multiple disciplines, including physics, computing, biology, and artificial intelligence, demonstrating how quantum principles are no longer abstract concepts but practical drivers of innovation.
I will be transparent in saying that portions of this book are intellectually demanding and, at times, exceeded my current technical grasp. However, that is not a criticism—it is a testament to the complexity and depth of the subject matter. The scale of the global race in quantum research cannot be overstated. It represents one of the most consequential scientific competitions of our time, with profound geopolitical, economic, and security implications. The nation or organization that successfully harnesses quantum capabilities will possess a transformative advantage.
What I appreciated most is Davies’s ability to convey both the promise and the risk inherent in quantum advancement. The same technologies that offer unprecedented insight into the nature of reality also present serious ethical and security challenges. This book underscores that scientific progress is not value-neutral and must be approached with responsibility and foresight.
While this is not light reading, it is an important and thought-provoking book. I am grateful for the opportunity to engage with a book that expands understanding of both the possibilities and the consequences of Quantum 2.0.
Thank you to Paul Davies, the University of Chicago Press, and NetGalley for the ARC.

I’ve been reading a lot of books about physics and quantum physics recently and I was very excited when I saw this for download on Netgalley. I’m glad I got a copy of this for review and I had a good time reading it overall.
Books about any kind of physics can be incredibly difficult to parse depending on who is writing this but I found this very easy to read and understand. It talks about a wide variety of topics in the find (some more speculative with less proof that the thing is realistic or can ever happen) and everything held my attention throughout. It definitely veers to the wild speculation side of things toward the end of the book but that doesn’t much takeaway from everything that came before it.
Overall I had a really good time with this and recommended it.
