‘Everything is going to be turned upside down’: Michio Kaku on the new world of quantum computing

If you’ve ever wondered how an invisibility cloak would work, how to terraform Mars, how to make a forcefield, whether we’re living in a Matrix-like simulation or how far we are from a working teleportation device, Michio Kaku is your man. In books such as Physics of the Impossible, Physics of the Future and Parallel Worlds, Kaku combines the scientific chops of the theoretical physics professor he is with the gee-wow wonder of a sci-fi geek.

That’s apt for someone who grew up worshipping at the twin altars of Albert Einstein and Flash Gordon. ‘It all started when I was eight,’ he says. ‘All the newspapers said that a great scientist had died. And they said that on his desk was a manuscript that he could not finish. I was fascinated by that. And so I looked up who was this man who could not finish this book. What was in it? Well, the man’s name was Albert Einstein.
