Book summary

Is the universe actually a giant quantum computer? According to Seth LloydProfessor of Quantum-Mechanical Engineering at MIT and originator of the first technologically feasible design for a working quantum computerthe answer is yes. This wonderfully accessible book illuminates the professional and personal paths that led him to this remarkable conclusion.

All interactions between particles in the universe, Lloyd explains, convey not only energy but also informationin other words, particles not only collide, they compute. And what is the entire universe computing, ultimately? Its own dynamical evolution, he says. As the computation proceeds, reality unfolds.

To elucidate his theory, Lloyd examines the history of the cosmos, posing questions that in other hands might seem unfathomably complex: How much information is there in the universe? What information existed at the moment of the Big Bang and what happened to it? How do quantum mechanics and chaos theory interact to create our world? Could we attempt to re-create it on a giant quantum computer?

Programming the Universe presents an original and compelling vision of reality, revealing our world in an entirely new light. [via]
