abstract

What is fundamentally quantum? We argue that most of the features, problems, and paradoxes -- such as the measurement problem, the Wigner's friend paradox and its proposed solutions, single particle nonlocality, and no-cloning -- allegedly attributed to quantum physics have a classical analogue if one is to interpret classical physics as fundamentally indeterministic. What really characterizes non-classical effects are incompatible physical quantities, which, in quantum quantum theory are associated to the fundamental constant $\hbar$.

  1. Classical and quantum mechanics across representations: an operational reading of the Wigner Weyl correspondence

    quant-ph 2026-07 conditional novelty 5.0 of 10

    The robust classical–quantum boundary across Wigner–Weyl representations is noncommutative star-multiplication, not negativity or the choice of phase-space versus Hilbert-space language.

  2. A Classical Analogue of Entanglement for a Kicked Top

    quant-ph 2024-11 conditional novelty 5.0 of 10

    Classical mutual information between phase-space subsystems of a kicked top grows at about half the Lyapunov exponent in chaotic regions and slowly in regular regions, mirroring known signatures of bipartite entanglement.

  3. Is there any Trinity of Gravity, to start with?

    gr-qc 2024-11 unverdicted novelty 2.0 of 10

    The teleparallel equivalents of general relativity are reformulations with unobservable extra structures, so there is no geometric trinity of gravity.
