" Several of the new proposals have at their core the concept that the world is made of information. This can be summarized in John Wheeler’s slogan “it from bit,” modernized as “it from qubit,” where a qubit is a minimal unit of quantum information, i.e., a quantum binary choice, as in our story about pet preference. In practical terms, this program imagines that all physical quantities are reducible to a finite number of quantum yes/no questions, and also that evolution in time under Rule 1 can be understood as processing this quantum information as a quantum computer would.
