Superinformation

Superinformation

Superinformation is a medium capable of containing information that specifies particular physical states in which copying is impossible. Usually this is in relation to quantum computing.

In the Constructor theory of fundamental physics, which expresses physical laws in terms of what physical transformations or tasks are possible versus which are impossible, superinformation is a special case of quantum information. In this schema, the concept of superinformation is as a medium capable of containing information that specifies particular physical states in which copying is impossible in the realm of quantum computing. Or, in other words, quantum information is an instance of superinformation.

This allowed for the display of properties associated with quantum information processing and the information of what a user cannot do in a superinformation medium, allowed researchers to discover new information-processing power that is a property of quantum systems. As well, measuring the state of a superinformation medium inevitably disturbs the medium, and because it is forbidden to make an exact copy of certain sets of states in a superinformation medium, there is a forced uncertainty into the outcome of a measurement. This allowed researchers to encode information in two superinformation media in such a way that makes it impossible to retrieve it by measuring the single subsystem separately, meaning entanglement is inevitable. Whereas in a classical medium entanglement is impossible.

A scheme in superinformation theory.

The superinformation theory offers a way to account for the unpredictability observed in quantum measurements based on superinformation being inherently non-probabilistic. The new perspective offers a new possibility in the search for a successor to quantum theory. As well, there is a belief that superinformation theory may help the notion of "relative state," which is important to unitary quantum theory. As well, superinformation may be merged with a proposed constructor theory of thermodynamics, which could have bearing on quantum theories of thermodynamics.

February 8, 2015
Superinformation is introduced as an information media in which certain tasks, with a natural constructor-theoretic definition, are impossible.
May 23, 2014
A paper posted to arXiv proposes constructor theory, which claims success toward the goal of devising a theory of everything by unifying the separate theories used to describe information processing in classical systems and in subatomic, quantum objects.
