Re: [Fis] Is quantum information the basis of spacetime?

I don't think that Bell's inequality shows indeterminacy, m3aning randomness, or chance. It does show entanglement. There are quantum that are reversible (some are macroscopic). In most measurements there is quantum decoherence, which breaks up entanglement, and has been compared to

Re: [Fis] Is quantum information the basis of spacetime?

Dear all, I make the last remark about "physical information". The main problem of quantum physics is to justify so called IRREDUCIBLE QUANTUM RANDOMNESS (IQR). It was invented by von Neumann. Quantum randomness, in contrast to classical, cannot be reduced to variations in an ensemble.

Re: [Fis] Is quantum information the basis of spacetime?

More on Quantum information and emergent spacetime, this time by Erik P. Verlinde: Emergent Gravity and the Dark Universe There is a less formal review at http://m.phys.org/news/2016-11-theory-gravity-dark.html I consider the idea very speculative, as I have

Re: [Fis] Is quantum information the basis of spacetime?

Dear Alex and colleagues, Thank you for the reference; but my argument was about “meaning”. “Meaning” can only be considered as constructed in language. Other uses of the word are metaphorical. For example, the citation to Maturana. Information, in my opinion, can be defined

Re: [Fis] Is quantum information the basis of spacetime?

Dear Loet and Fis Colleagues, Are you aware of Roy Frieden's 'Physics from Fisher Information'. His book was published in the 1990s. I consider it a very powerful statement. Ultimately everything we can detect at both macroscopic and microscopic levels depends on information production from a

Re: [Fis] Is quantum information the basis of spacetime?

Dear Marcus, When considering things in terms of "functional significance" one must confront the need to address "meaning" in terms of both the living and the physical . . . and their necessarily entangled nature. “Meaning” is first a linguistic construct; its construction requires

Further to John's original note . . . and then to Pedro's further note > It would neatly apply to the living but also to the physical < This is, of course, a recurring issue for FIS – the matter of meaning . . . or even, what is "information?" When it comes to defining "meaning" (or information)

Re: [Fis] Is quantum information the basis of spacetime?

Dear Mark and all, I agree with your criticisms on Floridi. My own look like this: In his paperA defense of information structural realism (Synthese 2009, Vol. 61, No. 2, pp. 219-253) Floridi argues that

Re: [Fis] Is quantum information the basis of spacetime?

Dear Moises and all, Floridi has an excellent chapter in his "philosophy of information" called "Against digital ontology". It's worth quoting the two fundamental questions he asks about digital ontology: "a. whether the physical universe might be adequately modelled digitally and

Re: [Fis] Is quantum information the basis of spacetime?

Dear FISers. I was very excited with the John’s first message informing that a group of scientists is discussing again the role of Information in Physics. The high impact on FIS list of John’s post (13 replies from different persons in 2 days) shows that it is yet an open discussion. Thank you

Re: [Fis] Is quantum information the basis of spacetime?

Andrei, have you tried with information as "distintion on the adjacent"? It would neatly apply to the living but also to the physical, i think. Best --Pedro Enviado desde mi dispositivo Samsung Mensaje original De: Andrei Khrennikov Fecha:

Re: [Fis] Is quantum information the basis of spacetime?

Well, Joseph, you don't have to go far to get the desired definition of information as an operator (produced quantity). The only prerequisite is to be ready to discard the practice, ideas, philosophy and ideology of the definitions relating to commutativity. This is heresy, I understand. On the

Re: [Fis] Is quantum information the basis of spacetime?

Dear All, I agree with the consensus I see emerging. Andrei shows the problem of trying to pin down a complex process with a single term - information. And I agree with Rafael that information must have a valence. On the other hand, as such, information cannot be completely defined

Re: [Fis] Is quantum information the basis of spacetime?

Andrei, maybe the concept of message as already used by Shannon and Weaver in specific engineering contexts (this must not be always the case) is more appropriate and also able to speak about 'information' as what is 'in' a message 'for' a receiver. Best. Rafael Hello Andrei - I am with you -

Re: [Fis] Is quantum information the basis of spacetime?

Hello Andrei - I am with you - sharing you sentiment. Information only pertains to living organisms and entails some signals that help them make a choice. A black hole makes no choices - it is ruled by the laws of physics. Abiotic systems have no information. A book is a set of signals that a

Re: [Fis] Is quantum information the basis of spacetime?

I may understand why in "quantum foundations" nobody can define rigorously the basic term "information". But, in agreement with Progogine, Brillouin, etc. information mays be defined rigorously in macro -systems. I could explain more in french. Cordialement. M. Godron Le 04/11/2016 à
