I would like to know if any of you think there's any sort of connection, analogy, or common features between, sets in set theory and wave functions in QT?

Wave functions lack trajectories, so do sets. Wave functions also distribute over areas, as sets can do. To my understanding, wave functions are also subject to decomposition; for example, an atom has an associated wave function, and this can decompose into the associated wave functions of the particles atoms are believed to be composed of. In exactly the same way, we can view the atom as a set, containing subatomic particles as its elements.

As such sets of objects may correspond to unique superpositions.

I would like to know if I am correct in my analysis and if anyone knows of any explicit common features or properties of mathematical sets and wave functions?

The only common feature is that you can define any function by sets. I think your comparison is too far-fetched to make any sense.

In this lecture at 1:17:20 and forwards (Lecture 1 | Modern Physics: Quantum Mechanics (Stanford)) Leonard Susskind describes the differences between the states in classical mechanics and quantum mechanics. Basically, states in classical mechanics are points in a set (phase space). In quantum mechanics states do not form sets. Instead, states are vectors in vector spaces over the complex numbers.

A vector space is a set of elements together with a field (like the real or complex numbers) called vectors with some algebraic operations defined on these sets. Today nearly everything in math is based on set theory.

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. Towards the end of the first lecture for the Qiskit Global Summer School 2025, Foundations of Quantum Mechanics, Olivia Lanes (Global Lead, Content and Education IBM) stated...

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
