How did a radical new theory of nature - quantum mechanics - revolutionize our world? Where
might it take us next? And why do we still not understand it? In this exhilarating and
sometimes mind-bending book renowned scientist and author Paul Davies tells the gripping story
of how beginning with an iconic mathematical equation in the 1920s a radical new theory of
nature - quantum mechanics - burst upon the modern world and how today we are on the cusp of
the second great quantum technology revolution. Quantum 2.0 reveals how exotic states of
matter that have no counterpart in the everyday world are being harnessed to enable forms of
teleportation and 'spooky' telepathic links between remote places. Powerful new tools such as
quantum computers quantum cryptography and the quantum internet have attracted billions of
dollars of investments triggering a frantic quantum arms race. And appearing on the horizon is
the most awesome and game-changing prospect of all - quantum AI. Yet underpinning this
dazzling promise lies a paradox. Although quantum mechanics is the most successful scientific
theory ever quantum systems possess properties that defy intuition and shred everyday notions
of reality. Albert Einstein could never quite believe it. And decades after Erwin Schrödinger
introduced his famous cat paradox scientists are still divided over how to make sense of the
weird quantum realm one where ghostly quantum particles produce tiny forces in nanotechnology
cause black holes to evaporate - and may even be making the universe expand faster and faster.
Indeed cosmologists believe the imprint of a quantum process remains etched into the
afterglow of the big bang. Quantum 2.0 takes the reader gently from the basic concepts to the
cutting edge inviting us all to peek into the new wonderland of quantum physics and glimpse
its stunning implications.
