Superposition status in the different interpretations.

Click For Summary
SUMMARY

The status of superposition in quantum mechanics varies significantly across different interpretations. In many-worlds interpretation (MWI), superpositions are ascribed a real-world status, while in Copenhagen interpretation (CI), they are viewed as a reflection of our ignorance prior to measurement. Superpositions exist in a multidimensional Hilbert space, and their evolution is governed by the Schrödinger equation. The application of the Born rule consistently yields probabilities for classical-like outcomes.

It is not clear to me what is the status of superposition in each interpretation. For instance, if I google I don't get much talk about it. Is superposition tied to probability or can be considered as separate.

Superpositions of quantum states exist in a multidimentional Hilbert space and they are not observable. Most every interpretation treats them differently - from ascribing a real world status(e.g. some forms of the MWI) to being nothing but our ignorance before measurement(CI).
The multitude of many wavefunctions form a Hilbert space and the Schroedinger equation determines how a particular wavefunction evolves over time. When you solve the equation and apply the Born rule, you always get probabilities for classical-like results('particles').
