I am super happy to be published (it is not my work, by the way) as I find it to be a very interesting entry point into the connection between KD quasiprobability and the emergence of classical objectivity from the perspective of Darwinism.

Compatibility of quantum measurements and the emergence of classical objectivity

The study of measurements in quantum mechanics exposes many of the ways in which the quantum world is different. For example, one of the hallmarks of quantum mechanics is that observables may be incom...
