This book is a used item that sells for around 3,700-7,000 yen. I stored it on a bookshelf after purchasing it without reading it. It's in very good condition. There's a very slight crease on the edge of the book cover, but I think it's at a level where it could pass for new at a bookstore. If you'd like to see more product images, I'd be happy to provide them, so please comment. Why does the universe exist? It exists to compute. What is it computing? It is computing the universe itself, that is, itself... According to quantum information theory, which has developed with the advancement of quantum technology that handles ultra-small particles, the universe is a giant quantum computer that creates itself through computation. And the fact that the universe is filled with diverse objects and presents a complex appearance seems to be due to this "computing" ability of the universe. The quantum world, made up of elementary particles, is where absurd things like a cat being both alive and dead can happen. This is a bold and stimulating scientific explanation by Seth Lloyd, a leading expert on quantum computers, which use quantum mechanics and have capabilities far beyond conventional computers. - Title: Programming the Universe: A Quantum Computer Scientist Takes on the Cosmos - Author: Keiji Mizutani - Language: Japanese - Genre: Science Explanation - Publisher: Shoeisha Thank you for viewing.
