2). Diving into the quantum world Quantum mechanics deals with the structure, elements, and functions of our microcosmos, i. e., with atoms. Quantum physics is all about probabilities where the
Quantum tomography is a method to experimentally extract all that is observable about a quantum mechanical system. We introduce quantum tomography to collider physics with the illustration of the ... physics is conventionally set up in a framework of unobservable and model-dependent scattering amplitudes. In quantum tomography these unobservable features are skipped to deal directly with observables

Using a discursive perspective, in this study of three introductory quantum physics courses at two Swedish universities, we instead ask ... to have high expectations for the quantum physics course and generally express that they appreciate the course more than other courses. Nevertheless, our analysis shows that the ways of being a ''good
Using effective field theoretical methods, we show that besides the already observed gravitational waves, quantum gravity predicts two further massive classical fields leading to two new massive ... interesting consequences for different branches of physics, from particle physics and astrophysics to cosmology. To identify these new fields, we calculate the leading quantum gravitational corrections to the
