Quantum computing
Quantum computing is perhaps the weirdest technology ever devised, carrying out calculations via the almost-incomprehensible strangeness of quantum phenomena. The first quantum computers are now appearing, accompanied by a wave of hype. Is it real or fantasy? Alice-in-Wonderland quantum physics requires you to believe the impossible, and it’s not easy even for scientists to tell whether this next big thing is an illusion.
Quantum physics is founded on the observation that very small particles do not behave like familiar human-scale objects. They are fuzzy, and can seemingly be in several places at once, or teleport through barriers (‘quantum
