Morbert's latest activity

From the paper: I suspect this is the part of the paper that will be most alien to readers (apart from the algebraic QFT which will be...

The interpretation would be the conceptualization of a quantum system as a system with a definite classical configuration, evolving...

From section 3.9 "The decoherent-histories framework" in "The Emergent Multiverse" by Wallace

It offers a reformulation that might prove to be useful beyond foundational/conceptual questions, and there would be no problem in...

No. The operationalis/instrumentalist account is probabilistic and has no objective collapse. Consistent histories is probabilistic and...

That's true, but cases ii and iii correspond to situations where Alice and Bob enter their respective laboratories and ask Charlie and...

I still need to read the paper properly to give a proper response, but in the AOE section they have "ii. P(a|cd,...)" and "iii...

I'm not sure what you mean by this but I don't think I agree, and it would take us too far into philosophy for my comfort.

The only relevance systems that partition into a measured system and a measurement device/environment have is they are the systems we...

Remember though that in this formalism, the configuration a system or subsystem is in is not indexed to any observer. In which case if...

I don't see how the bit in bold is true if dynamics are non-Markovian. [edit] - I.e.: AOE + Markovian dynamics = joint probability...

@Sambuco Re/ Wigner's friend:

I am not sure what GSC is. Do you mean GSS (generalized stochastic system)? What Barandes shows is that we can associate any quantum...

This stochastic formalism rejects everywhere-divisible dynamics, something Bong et al don't consider. This is perfectly reasonable...

Honestly, I'm not, as it is what connects a mathematical result to a physical interpretation. It's what lets you regard a quantum system...
