physika reacted to Matterwave's post in the thread Undergrad Spatial separation of entangled particles implies physical separability? with
Like.
Not for the EPR state. It is still an entangled state and not a product state. When EPR says (something like) "after T, the two... -
physika reacted to loop quantum gravity's post in the thread Graduate So, if RQM isn't consistent; what makes us believe that QFT is? with Like.
A conundrum indeed.... :cool: I still don't understand how you can use methods of semiclassical analysis in physics; what does it mean...
-
physika reacted to Matterwave's post in the thread Graduate Časlav Brukner, Richard Healey, and von Weizsäcker on the wave function with Like.
I am inclined to push back on this unless Brukner is willing and able to provide a precise definition of measurement and observation...
-
physika reacted to Demystifier's post in the thread Graduate Entanglement swapping and Bohmian mechanics with Like.
If I have to choose one of those, I choose i). You cannot actually observe the A/D correlation before you do the swap. The data from...
-
physika reacted to Morbert's post in the thread Graduate Entanglement swapping and Bohmian mechanics with Like.
If you are carrying out the textbook standard QM calculation of unitary evolution -> measurement -> collapse (preparation) -> unitary...

physika reacted to Demystifier's post in the thread Graduate Entanglement swapping and Bohmian mechanics with Like.
In the other thread, @DrChinese says: "Show me any Bohmian step by step explanation of the mechanics - in precise time order as required...

physika reacted to Roberto Pavani's post in the thread Graduate Pilot wave persistence after measurement in Bohmian entanglement with Like.
I have a few questions that I hope the experts here can clarify: 1. On the foliation in practice: In a real experiment, Alice and Bob...

physika reacted to Roberto Pavani's post in the thread Undergrad Particle vs Wave Interpretations of QM with Like.
Fair enough. Every theory has to stop somewhere and take something as fundamental. My only point is that, when several distinct...

physika reacted to bhobba's post in the thread Undergrad Particle vs Wave Interpretations of QM with Like.
Physics degrees come in a number of flavours. General physics degrees are often done in a double major with applied math. This can...
-
physika reacted to QuarkyMeson's post in the thread Undergrad Particle vs Wave Interpretations of QM with Like.
Physics gives us mathematical models of reality, not reality itself, and even extremely successful models are only approximations, and...

physika reacted to pines-demon's post in the thread Undergrad Carroll interviews Barandes on Indivisible Stochastic QM with Like.
How I am not following this discussion?! Edit: Oh I see, this is that 2025 podcast.
-
physika reacted to gentzen's post in the thread Undergrad Carroll interviews Barandes on Indivisible Stochastic QM with Like.
For me, checking your texts for omitted words and unnecessary typos before posting would be enough.

physika reacted to gentzen's post in the thread Undergrad Carroll interviews Barandes on Indivisible Stochastic QM with Like.
Fra‘s frequent typos, word omissions, and grammar mistakes contribute a lot to making his posts hard to decipher: Fra may believe...
-
physika reacted to renormalize's post in the thread Undergrad Particle vs Wave Interpretations of QM with Like.
OK, I think we'll have to agree to disagree:wink:, at least until one of us finds an appropriate reference or does an actual...

physika reacted to gentzen's post in the thread Undergrad Particle vs Wave Interpretations of QM with Like.
My "actual math" rather tells me that "the slits have a finite separation that is small compared to the wavelength of the momentum...
