What is it about?
We examine how Schrödinger cat states change when extended to quantum systems with infinitely many degrees of freedom. This question is studied both within the traditional theory of bosons and within a newly introduced class of generalized bosons. Each framework reveals distinct features and adds new nuance to our understanding of macroscopic quantum superposition.

Why is it important?
The contrast with a newly introduced class of generalized bosons shows that the close connection between coherent states and Schrödinger-cat-like superpositions is far from universal, shedding new light on the structure of quantum theory.
Perspectives
Beyond their mathematical interest, generalized bosons offer new perspectives on collective excitations in solid-state physics and underpin novel information architectures relevant to post-quantum cryptography. Exploring further connections between these areas remains an exciting direction for future research.
