I've been thinking about the difference between quantum physics and quantum mechanics. What are the difference?

Is quantum physics just a subfield name, and within that there are quantum mechanics and quantum field theory etc. or are all of these three independent subfields of physics?

Is there a reason why you put THIS much effort into what goes in a "name" such as this?

For me, this type of categorization has no significance and is quite interchangable. It is when a name effects the workings of physics and how it is practiced, then it matters (example: a "fermion" is not interchangable with a "boson" where the characteristics matters).

I apologize for the inconvenience.
 
in the common sense, if one's book use quantum physics
this book is written for beginners.
while quantum mechanics "terminology" is written for graduate oriented students and researchers.
 
We often see discussions about what QM and QFT mean, but hardly anything on just how fundamental they are to much of physics. To rectify that, see the following; https://www.cambridge.org/engage/api-gateway/coe/assets/orp/resource/item/66a6a6005101a2ffa86cdd48/original/a-derivation-of-maxwell-s-equations-from-first-principles.pdf 'Somewhat magically, if one then applies local gauge invariance to the Dirac Lagrangian, a field appears, and from this field it is possible to derive Maxwell’s...
I read Hanbury Brown and Twiss's experiment is using one beam but split into two to test their correlation. It said the traditional correlation test were using two beams........ This confused me, sorry. All the correlation tests I learnt such as Stern-Gerlash are using one beam? (Sorry if I am wrong) I was also told traditional interferometers are concerning about amplitude but Hanbury Brown and Twiss were concerning about intensity? Isn't the square of amplitude is the intensity? Please...
I am not sure if this belongs in the biology section, but it appears more of a quantum physics question. Mike Wiest, Associate Professor of Neuroscience at Wellesley College in the US. In 2024 he published the results of an experiment on anaesthesia which purported to point to a role of quantum processes in consciousness; here is a popular exposition: https://neurosciencenews.com/quantum-process-consciousness-27624/ As my expertise in neuroscience doesn't reach up to an ant's ear...
