Science a GoGo's Home Page Forums General Discussion Physics Forum At last an explanation of quantum entanglement

Beyond the David Bohm out there stuff the CMBR actually acts like a universe observer be it benign.

http://en.wikipedia.org/wiki/Observer_effect_(physics)

=> An important aspect of the concept of measurement has been clarified in some QM experiments where a single electron proved sufficient as an "observer" — there is no need for a conscious "observer".

I revived this thread because this paper release really belongs here rather than starting a new thread.

In the thread we discussed how we now understood quantum coherence and entanglement in a more fundamental ways. We discussed the mixing and sharing of entanglement between photons, atoms and solids.

One of the more interesting tests on the stability of quantum coherence with this cross mixing has recently reached the general media

The actual paper:

The image that shows it up best to a layman with light being trapped:


It is interesting outside just quantum computing and a truly impressive piece of science.

There is an interesting extension that many fundamentalist scientists are urging be tested ... anyone want to hazard a guess what it is we would like to try?

Bonus question: Is the light really stopped in a true science sense and what is actually happening?

Physics has done a bit more technical write up but should be still layman understandable

Great discovery! Think what this might mean. According to the concepts of the “implicate order” the cosmos is infinite, and every part of the cosmos is the cosmos. Every part embodies all the properties of the cosmos. The cosmos possesses consciousness, therefore every part of the cosmos, right down to the smallest quantum particle, must possess consciousness. An electron is a conscious observer!

We cannot observe this directly because we are restricted to 3+1 dimensional perception, but QM provides a window to the infinite, through which we are just beginning to look.

Careful in extracting to far Bill S.

QM is simply a description of the behavior it does not imply any why or how.

One of the better possible why and how in my opinion and it is only an opinion was published recently

Interesting link, Orac. I'll have to read it again to see where it fits into this discussion.

BTW, my favourite quote from Lawrence Krauss is: "By nothing, I do not mean nothing," It comes from the book I am reading at the moment: "A Universe from Nothing".

A description of the behaviour of a person makes no direct statement about the reason for that behaviour, but it might suggest areas of that person’s history in which an explanation might be sought.

If QM describes a behaviour in nature that seems to link to some particular problem or concept, surely that link is worth investigating. Of course, it is important to avoid suggesting that this is what QM is actually saying; when the line of reasoning is simply an extrapolation.

If I look through the window into my garden (yard), the window tells me nothing about the garden, but without it I would not know that there were beautiful butterflies on my buddleia.

QM as written in mathematics is a very ugly beast, I saw a great blog post on it

http://theeternaluniverse.blogspot.com.au/2009/09/just-how-prettyugly-is-standard-model.html

Now that's a lot of very complicated mathematics which looks like nothing how we see the world.

Now we have place QM firmly in it's position in the universe as a fundamental property of the universe we have to deal with the measurement problem.

=> http://en.wikipedia.org/wiki/Measurement_problem

Our initial attempts at the interpretation had invisible waveforms etc.

In the post 2008 era we now understand quantum decoherence is what the early interpretations tried to describe

=> http://en.wikipedia.org/wiki/Quantum_decoherence



What all that is telling you is that the universe extends outside what we can see and touch ... above they call it ... beyond the realm of measurement.

The previous post article I linked brings in GRAVITY and unifies it with QM is this hidden realm in a scientific way.

What I am steering away from is "consciousness of an observer" arguments

=> http://en.wikipedia.org/wiki/Consciousness_causes_collapse#.22Consciousness_causes_collapse.22

I take an out on this mumbo jumbo as do most scientists

=>To many scientists the dualist interpretation fails a priori to compete with other interpretations of quantum mechanics because "consciousness causes collapse" relies upon a dualistic philosophy of mind (in particular, a radical interactionism), which is inconsistent with the materialist monism presupposed by many physicists.

I am a very very very materialist monism person

I fully agree with you there. It doesn't take consciousness to "observe" the collapse, or whatever you want to call it. It just takes something to be affected by it.
