The term “quantum” is everywhere these days. From quantum computers to even quantum refrigerators, it seems like everyone is jumping on the bandwagon. But what does it all mean? Paul Davies’s new book, Quantum 2.0: The Weird Physics Driving a New Revolution in Technology, seeks to clarify this. Davies is a theoretical physicist and leads the Beyond Center for Fundamental Concepts in Science at Arizona State University.
His book breaks down the basics of quantum mechanics—how it has shaped science for over a century and how it will continue to do so. He argues that we’re entering a new phase: Quantum 2.0, where we can manipulate individual particles like electrons and photons. This allows for deeper levels of control over technology and information.
So, what was Quantum 1.0? Davies explains that it all began around 1925, when quantum mechanics first emerged. This revolutionary theory helped us understand everything from tiny subatomic particles to massive stars. It gave rise to the laser, microchips, MRI machines, and much more. To celebrate this milestone, UNESCO has declared 2025 the International Year of Quantum Science and Technology, highlighting the ongoing advancements in this field.
Many products now claim to be “quantum,” but Davies warns that not all of these claims are genuine. True quantum technology goes beyond buzzwords; it manipulates physical properties at a fundamental level. For example, real quantum devices exploit phenomena like quantum entanglement and superposition.
Yet, quantum mechanics can be perplexing. It challenges our everyday perceptions of reality. At the quantum level, particles don’t have definite properties until they are measured. This creates a disconnect between our tangible world and the strange behaviors of subatomic particles, leaving scientists puzzled even today.
Davies mentions a fascinating aspect of quantum science: quantum biology. Erwin Schrödinger, a pioneer of quantum theory, puzzled over how life seemed to defy these laws. Recently, researchers are exploring whether quantum effects play a role in biological processes, suggesting that life’s complexities might be tied to quantum principles. This area is still under debate, but it opens intriguing possibilities for understanding consciousness and life itself.
Talking about AI, Davies stresses that traditional artificial intelligence relies heavily on quantum principles. In the future, we might see “quantum AI,” an even more advanced form that can perceive multiple realities at once. This raises questions about the nature of consciousness and the potential for AI to think in ways we cannot yet comprehend.
Looking ahead, what might Quantum 3.0 look like? Davies suggests it could involve mind-machine interfaces, allowing us to connect our brains with quantum computers. While this idea is thrilling, it also sparks concerns about privacy and the future of human interaction.
Ultimately, quantum science continues to reshape our understanding of existence itself. The idea that observation creates reality challenges our very notions of what is real. The next generation of physicists will face the exciting task of unraveling these complexities.
Quantum 2.0 was released in the UK on November 29, 2025, and is now available worldwide. For more insights into quantum science, check out this link.
