A technology that promises many revolutions, from medicine to finance.The quantum computer of the future could perform calculations in seconds that would take millions of years for the most powerful supercomputer in existence today. But how do these “impossible computers” work? And why are they so extraordinarily efficient? The first quantum revolution transformed our understanding of the world, forcing us to abandon a deterministic view of the universe. The second revolution, already underway, aims to build real machines: computers that follow quantum logic, an intrinsically secure Internet, and ultra-precise sensors that will change our daily lives, from medicine to cybersecurity. It is true that “God plays dice,” and with those dice we can create the technology of the future. Written in a clear and accessible style, this book guides the reader from an understanding of the fundamental principles of quantum theory to the new technologies that will transform the world.Praise for THE IMPOSSIBLE COMPUTER"Among the many books seeking to explain quantum physics to nontechnical readers, The Impossible Computer stands out because of its unique and original emphasis: explaining how apparently abstract scientific investigations into the nature of reality are increasingly affecting every detail of our daily lives. To encourage us along this intellectual journey, from philosophy to technology, is far from easy. The authors accomplish it by employing familiar analogies in unfamiliar ways, to make understandable quantum concepts such as superposition and entanglement, and their many and varied applications to fields such as computation, keeping secrets, and diagnostics of unprecedented accuracy." Michael Berry, University of Bristol, UK"Casati and collaborators invite the reader into the strange and fascinating world of quantum computation with clarity, wit, and elegance. It is a compelling introduction to the quantum information revolution—and to the probability that quantum computing will reshape the way we understand the world.” Eric Heller, Harvard University, USA
