Many scientists are beginning to realize that we live in an information universe where information about the physical makeup of reality resides in an ocean entangled bits of quantum information called ‘qubits’. How this information collects determines the state of matter and spin of elementary particles  These phases show up in temperatures near absolute zero where the motion is practically still. -KHF

Using Topology to Classify Phases

“It’s not a particular law of physics” that these scientists seek, said Michael Zaletel, a condensed matter theorist at Princeton University. “It’s the space of all possibilities, which is a more beautiful or deeper idea in some ways.” Perhaps surprisingly, Zaletel said, the space of all consistent phases is itself a mathematical object that “has this incredibly rich structure that we think ends up, in 1-D and 2-D, in one-to-one correspondence with these beautiful topological structures.”
