thanks to Garrett for alerting us to the fact that the summaries and ABSTRACTS for the 30 FQXi projects are now available(adsbygoogle = window.adsbygoogle || []).push({});

several of them are interesting to read

Project Title:

Relational Physics with Real Rods and Clocks and the Measurement Problem of Quantum Mechanics

Technical Abstract:

When quantum mechanics is formulated in terms of relational notions, as is required by any theory of nature that includes gravity, it takes a different form than the usual one. In particular, there is a natural loss of coherence in quantum states when time and space are measured by realistic clocks and rods, which have quantum and other types of uncertainties in their measurements. We propose to investigate the impact of this loss of coherence on the fundamental problems of measurement in quantum theory. The aim is to show that the use of real clocks and measuring rods in quantum theory, combined with interactions with the environment, effectively eliminates most of the well known issues with the problem of measurement in quantum mechanics. It also opens a new perspective to be explored on interpretational issues of the quantum theory, since in view of the fundamental loss of coherence some interpretations of quantum mechanics immediately lose their compelling nature, whereas others arise as more natural."
