After reading Seth Lloyd's book “Programming the Universe”(only once) I came up with a few questions. The way I understand it... He describes the fabric of space-time as consisting of an endless array of casual space (wires) and matter(quantum gates). The wires tell information where to go and meet at gates. One of these gates is the controlled-NOT op gate. This gate can be created by coiling two photons into a small tube with an atom in it and causing the photons to interact strongly with the atom. This type of quantum gate, along with the AND, COPY, and OR gates make up the matter that process information. After the interaction between the qbits(nuclear spins) and the quantum gate, space is told how to curve. The first question I have is basic... “Is this correct?” Next I would like to understand nuclear spin. Is everything made up of nuclear spins? What is spinning? Elementary particles? How is a sideways spin(registering 1 and 0 simultaneously) created? Then there is the idea of curved space. Could this complex subject be made any more simple for me? I am dizzy.
