Event-Based Quantum Mechanics: A Context for the Emergence of Classical Information

Abstract

This paper explores an event-based version of quantum mechanics which differs from the commonly accepted one, even though the usual elements of quantum formalism, e.g., the Hilbert space, are maintained. This version introduces as primary element the occurrence of micro-events induced by usual physical (mechanical, electromagnetic and so on) interactions. These micro-events correspond to state reductions and are identified with quantum jumps, already introduced by Bohr in his atomic model and experimentally well established today. Macroscopic bodies are defined as clusters of jumps; the emergence of classicality thus becomes understandable and time honoured paradoxes can be solved. In particular, we discuss the cat paradox in this context. Quantum jumps are described as temporal localizations of physical quantities; if the information associated with these localizations has to be finite, two time scales spontaneously appear: an upper cosmological scale and a lower scale of elementary “particles”. This allows the interpretation of the Bekenstein limit like a particular informational constraint on the manifestation of a micro-event in the cosmos it belongs. The topic appears relevant in relation to recent discussions on possible spatiotemporal constraints on quantum computing.

Quantum Mechanics Interpretation on Planck Scale

“…Here, it seems clear the difference between a line like the one analyzed in this paper, the 't Hooft or Winterberg, which is traditionally dynamic, even if pushed to the Planck scale, and other works that call into question the concept of time in the quantum realm and extend the emergency to the same space-temporal structure [98]. Some of these go in the direction of a convergence between the holography and the emergent space-time [99][100][101][102].…”

Hartle-Hawking boundary conditions as Nucleation by de Sitter Vacuum

“…In a oversimplified case, one considers non-symmetrized wave functions, despite one can argue that the nucleated entities are strongly correlated within a non-local framework. This is an "event-based" interpretation, which unifies cosmology and microphysics and is connected with the popular "timeless" approaches, see [18,30,70] and references within.…”

“…An interesting question concerns if such an assumption of absence of a classical space-time works beyond cosmology, maybe including the whole realm of quantum theory [16]. Some recent foundational scenarios go in the same direction [17,18]. In this work, the HH proposal is reanalysed starting from its recent generalization in [19].…”

General Relativistic Wormhole Connections from Planck-Scales and the ER = EPR Conjecture

“…This finds application to the ER = EPR conjecture-in this framework, geometry behaves as a geodesic tensor network that defines the quantum state properties of a fundamental quantum state of a given metric [55] and a virtual graviton exchange becomes equivalent to entanglement to which one can apply the concept of Penrose's decoherence of a quantum state [56]. In this crossing between locality of GR and the emergence of non-locality of QM as in [57,58], where de Sitter space-time is taken as the geometric structure of vacuum, the analysis of Einstein's equations can provide an additional support to the ER = EPR conjecture extended from AdS to dS [59] and to locally Euclidean space-times. This can be interpreted as the route to ER = EPR from general relativity.…”
