Programming the Universe
Is the universe actually a giant quantum computer? According to Seth Lloyd, the answer is yes. All interactions between particles in the universe, Lloyd explains, convey not only energy but also information–in other words, particles not only collide, they compute. What is the entire universe computing, ultimately? “Its own dynamical evolution,” he says. “As the computation proceeds, reality unfolds.” Programming the Universe, a wonderfully accessible book, presents an original and compelling vision of reality, revealing our world in an entirely new light.

What Hacker News says
- There is a common perspective that the physical world is computation. That doesn't mean that it's a simulation, only that information is being processed in a way that is very analogous to computation, and it is very useful for seeing it as such.
The world we live in is quantum in nature, and so it is very useful to think of the entire universe as a giant quantum computer.
In fact, one of the primary use cases for building a physical quantum computer we can program is the "simulation" of natural quantum systems, though that begins to stretch the word "simulation."
I'm not sure why you're so accusatory in this comment, but if you want to understand this better, I would recommend "Programming the Universe" by Seth Lloyd
- That would be a long list, given that I read a lot of books and would generally say that most of the books I've read were worth investing time in to some extent. But for what it's worth, here's a subset, cribbed from my previous HN comments:

- Programming the Universe by Seth Lloyd really helped me to understand this stuff. http://www.amazon.com/Programming-Universe-Quantum-Computer-...
- This is a really misleading article. What they're referring to is placing atoms (and molecules) into states of superposition where the state can be represented as 1/sqrt(2)|left> + 1/sqrt(2)|right>. This is an important first step towards quantum computers--being able to construct entangled systems of many q-bits, but this article is really quite poor in it's description. If you're really interested in this sort of stuff, I'd suggest reading Charles Seife's book entitled _Decoding the Universe_. It's about information theory and discusses quantum computing to a certain extent. I've also heard Seth Lloyd's book Programming the Universe is very good, but I have not read it.
- Programming the Universe: A Quantum Computer Scientist Takes On the Cosmos by Seth Lloyd.
It made me think about reality in a very novel way, and the nature of what a tautology really is, and it was extremely readable considering how cerebral it is.
