The Pragmatic QFT Measurement Problem and the need for a Heisenberg-like Cut in QFT

  title={The Pragmatic QFT Measurement Problem and the need for a Heisenberg-like Cut in QFT},
  author={Daniel Grimmer},
Despite quantum theory’s remarkable success at predicting the (statistical) results of experiments, many philosophers worry that it nonetheless lacks some crucial connection between theory and experiment. Such worries are at the root of the Quantum Measurement Problem. We can identify two kinds of worries: 1) pragmatic: it’s unclear how to model our experiments to extract theoretical predictions, and 2) realist: there is no realist narrative for the experiment underlying these theoretical… 
What does it take to solve the measurement problem?
We summarise different aspects of the measurement problem in quantum mechanics. We argue that it is a real problem which requires a solution, and identify the properties a theory needs to solve the


The sky is blue, and other reasons quantum mechanics is not underdetermined by evidence
I criticize the widely-defended view that the quantum measurement problem is an example of underdetermination of theory by evidence: more specifically, the view that the unmodified, unitary quantum
Impossible Measurements on Quantum Fields
It is shown that the attempt to extend the notion of ideal measurement to quantum field theory leads to a conflict with locality, because (for most observables) the state vector reduction associated
Impossible measurements revisited
It is by now well-recognised that the na\"ive application of the projection postulate on composite quantum systems can induce signalling between their constituent components, indicative of a
Inter-theory relations in physics : case studies from quantum mechanics and quantum field theory
The relationship that is widely presumed to hold between physical theories and their successors, in which the successors in some sense explain the success of the theories they replace, is known

We propose and develop a measurement scheme for quantum field theory (QFT) in curved spacetimes, in which the QFT of interest, the “system”, is dynamically coupled to another, the “probe”, in a
Max Planck: the reluctant revolutionary
According to the standard story, which is unfortunately still found in many physics textbooks, quantum theory emerged when it was realized that classical physics predicts an energy distribution for
