• Abstract: In this paper, we discuss content and context for quantum properties. We give some examples of why quantum properties are problematic: they depend on the context in a non-trivial way. We then connect this difficulty with properties to the indistinguishability of elementary particles. We argue that one could be in trouble in applying the classical theory of identity to the quantum domain if we take indiscernibility as a core and fundamental concept. Thus, in considering indistinguishability as such a fundamental notion, it implies, if taken earnestly, that one should not apply standard logic to quantum objects. Consequently, we end with a discussion about novel aspects this new mathematics brings and how it relates to some issues associated with the quantum world's ontology and the classical limit. We emphasize that, despite several different ways of questioning classical logic in the quantum domain, our approach is distinct. It involves one of the core concepts of classical logic, namely, identity. So, we are in a different paradigm from standard quantum logics.

• Which features of quantum physics are not fundamentally quantum but are due to indeterminism? [0.0]
  We argue that most of the features, problems, and paradoxes attributed to quantum physics have a clear classical analogue. What really characterizes quantum physics boils down only to phenomena that involve $hbar$, i.e., incompatible observables.

  This paper presents an alternative approach to quantum entanglement, one that effectively resolves the logical inconsistencies without leading to logical contradictions. By addressing some of the inconsistencies within quantum mechanics, such as state superposition and non-locality, our method is constructed on the principles of paraconsistent logic.

  We show that quantum theory does satisfy the classical distributivity law once the full meaning of quantum propositions is properly taken into account. We show that the lattice of statistical propositions in classical mechanics follows the same structure, yielding an analogue non-commutative sublattice of classical propositions.

  We put forth a new theoretical framework for merging quantum information science and causal inference by exploiting entropic principles.

This approach can lay the foundations of identifying originators of malicious activity on future multi-node quantum networks.
