Rethinking Quantization: Toward a Local, Realistic Interpretation — •Falk Rühl — D52159 Roetgen, Auf der Alm 14

More than a century after the birth of quantum theory, its formalism has matured, but its interpretation remains entangled with the early 20th-century notion of 'early quantization'. In this conventional view, central to the Copenhagen interpretation, proposed by A. Einstein and N. Bohr, quanta are treated as discrete property carrying objects, generated at sources and transmitted without loss to distant targets.

In this talk, I will present an alternative framework: 'late quantization'. Here, quantum phenomena arise not from the emission, transfer, and absorption of discrete quanta, but from the interaction of radiation from all possible sources, with continuously evolving states of the targets themselves. This shift allows for a local and realistic interpretation of quantum processes, dispensing with the need for non-locality, wave-function collapse, or quantum jumps.

A key feature of this approach is that efficient detection of sources only occurs, when the source radiation drives closed cycles in the target's state space. This makes only a small subset of the continuously evolving 'beable' states of sources 'observable' states.

This new interpretation not only provides conceptual clarity but also eliminates longstanding quantum puzzles within a fully local and deterministic framework.
