bhobba replied to the thread A question about quantum entanglement.Information that would allow clock synchronisation. Thanks Bill -
What are these "things"? The quantum states in QFT are of the field. So, I don't understand what is meant by quantum states generated...

bhobba replied to the thread A question about quantum entanglement.The only out, if an out it is, is that it is just a computational device. It still is non-local, but of no concern. For quantum...

No, that's not what he said. He said they are a two-particle excitation of a quantum field. That's not the same as a one-particle...

bhobba replied to the thread Programs Help deciding between an applied math and physics bachelors.Can you please say where you live? If in the US, I would suggest applied math, then a graduate degree in mathematical physics, e.g...

bhobba reacted to Peter Morgan's post in the thread A question about quantum entanglement with
Like.
Art Hobson's "Fields and Their Quanta: Making Sense of Quantum Foundations" and his previous work, going back decades, has always seemed... -
Your reality check should kick in here, at this stage. Your equation 1) has to be dodgy. We've all agreed that 20 = 1 and all the...

bhobba replied to the thread A question about quantum entanglement.Regarding Feynman's view of QM, just before he died, he attended a seminar by his friend (and the guy in the office next door)...

bhobba reacted to Peter Morgan's post in the thread A question about quantum entanglement with Like.
For a field theory, there are, in the first instance, no particles to be entangled. The idea that each record of an event in a detector...

Please do not venture into personal speculation.

Different QM interpretations give different (and incompatible) answers to this question.

bhobba reacted to PeterDonis's post in the thread Undergrad How can light be a wave and particle at the same time? with Like.
It depends on what you want to use the term "light" to refer to. That's a question about words, not physics. I was, of course, using it...

bhobba reacted to Demystifier's post in the thread Graduate Obtaining NRQM from QFT: Issues, Folklores and Facts by Padmanabhan with Like.
It depends on what you mean by RQM. If by RQM you mean Bjorken & Drell 1, then yes, you can obtain it from Bjorken & Drell 2. But in...

bhobba reacted to Peter Morgan's post in the thread Graduate Obtaining NRQM from QFT: Issues, Folklores and Facts by Padmanabhan with Like.
There is no concept of a particle in axiomatic forms of QFT. We can add Wigner's definition of particles in terms of unitary...

bhobba reacted to Morbert's post in the thread Undergrad About wavefunction collapse and explaining single outcomes in different interpretations with Like.
You might be thinking of a decoherence timescale/rate (see eq 5.38 in https://arxiv.org/pdf/quant-ph/0105127 )
