Over the last 60 years, the size of a transistor has been reduced to a few nanometres, resulting in faster, cheaper and smarter computers. But the miniaturisation crusade in the silicon chip industry faces a wall of limitation—a wall that is governed by the laws of quantum mechanics. My job as a physicist is to break this barrier, and there is no better place to do this than in Germany. It is a place where walls fall down: social walls, political walls, and of course, the Berlin Wall, giving us hope that we can achieve the impossible.
