Quantum non-objectivity from performativity of quantum phenomena

Observation and Quantum Objectivity

Observation and Quantum Objectivity

The paradox of Wigner’s friend challenges the objectivity of description in quantum theory. A pragmatist interpretation can meet this challenge by judicious appeal to decoherence. On this interpretation, quantum theory provides situated agents with resources for predicting and explaining what happens in the physical world— not conscious observations of it. Even in Wigner’s friend scenarios, di¤...

On Classical and Quantum Objectivity

We propose a conceptual framework for understanding the relationship between observables and operators in mechanics. To do so, we introduce a postulate that establishes a correspondence between the objective properties permitting to identify physical states and the symmetry transformations that modify their gauge dependant properties. We show that the uncertainty principle results from a faithf...
