Dissipating the quantum measurement problem

An exponential behavior at all times is derived for a solvable dynamical model in the weak-coupling macroscopic limit. Some implications for the quantum measurement problems are discussed, in particular in connection with dissipation.

We propose an ontological reinterpretation of the quantum measurement problem using a process based framework. The photon is not treated as a particle or wave, but as a metastable process capable of transforming into multiple physical forms (thermal, electrical, chemical, or mechani- cal). The double slit experiment is reinterpreted as a spatially distributed process whose trans formation is either deferred to the detection screen or forced earlier by measurement near the slits. Interference arises not from wave behavior but from delayed transformation. Measurement corresponds to an ontological phase transition of the process, not to information acquisition or wavefunction collapse. It does not replace the standard quantum formalism, but offers an alternative ontological interpretation of it. Formally, this framework is expressed as a formal ontological schema articulated via primitive processual operators of differentiation, fixation, and dissipation (diff/fix/diss), rather than as a predictive mathematical formalism. This approach reframes the ontological basis of the measurement problem, eliminates observer-dependence, and aligns quantum phenomena with general principles of dissipative process ontology.

Abstract Collapse models constitute an alternative to quantum mechanics that solve the well-know quantum measurement problem. In this framework, a novel approach to include dissipation in collapse models has been recently proposed, and awaits experimental scrutiny. Our work establishes experimental bounds on the so-constructed linear-friction dissipative Diósi-Penrose (dDP) and Continuous Spontaneous localisation (dCSL) models by exploiting experiments in the field of levitated optomechanics. Our results in the dDP case exclude collapse temperatures below 10−13 K and 6 × 10 − 12 K respectively for values of the localisation length smaller than 10−6 m and 10−8 m. In the dCSL case the entire parameter space is excluded for values of the temperature lower than 6 × 10 − 9 K.
