Towards a New Technological Revolution

From teleportation to quantum computers, what new powers does the quantum world have to offer? The second quantum revolution is underway: the next technological era will be quantum. However, despite its many theoretical and experimental successes, quantum physics remains haunted by demons that are inaccessible to the layman, such as superposition, entanglement, contextuality and quantum indeterminacy. These notions cloak it in a halo of disquieting strangeness and mystery that it struggles to shake off. This book aims to pierce that halo by inviting readers to harness the magic of quantum physics.

The famous quantum paradoxes defy understanding. “Schrödinger’s cat is both dead and alive,” “a quantum computer computes in parallel worlds,” “quantum particles communicate instantaneously,” one hears. These ambiguous phrases sketch a mysterious world, populated by phenomena as fascinating as they are elusive such as superposition, entanglement, or indeterminacy.

Yet this baffling universe is at the heart of an imminent technological revolution. Computers with immense capabilities, sensors of unprecedented precision, inviolable communications: these are the new promises of quantum physics. Deconstructing the myths that surround it becomes imperative. This book aspires to lift the veil on this “magic” and to offer a clear understanding of its foundations, while exploring its concrete applications.

Set off on a fascinating journey into the heart of quantum strangeness, where the technologies of tomorrow are already taking shape.

Readership: All those very, very interested in popular science, learned readers.

Hippolyte Dourdent

Hippolyte Dourdent is a postdoctoral researcher at the Institute of Photonic Sciences (ICFO) in Barcelona. A physicist graduated from Institut d’Optique Graduate School and a PhD in theoretical physics from Université Grenoble-Alpes, he specializes in the foundations of quantum theory and explores its most fascinating and counter-intuitive aspects, from contextuality to indeterminate causality, as well as their uses in the field of quantum information processing.
