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.
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.

- Quantum computingThe study of computation systems that make use of quantum mechanical phenomena (eg entanglement and superposition). Quantum computers use qubits (rather than binary 0 and 1s) which can be in both states at the same time by being in a superposition of states.
- Constructor theoryConstructor theory expresses physical laws exclusively in terms of what physical transformations, or tasks, are possible versus which are impossible.
