Measurements on an entangled state[edit]

The diagram of Bob and Alice shows their axes rotated by 45 degrees. The text does explain why this is necessary. — Preceding unsigned comment added by 62.56.70.12 (talk) 08:42, 21 March 2012 (UTC)

I agree, I also think the diagram is confusing. Suggest rotating the Bob circle 45 degrees anti-clockwise and removing the caption '45 (degrees)'. Then it makes sense. Count ludwig (talk) 13:34, 7 April 2013 (UTC)
I also agree with Count ludwig.Septate (talk) 11:35, 6 July 2014 (UTC)

The section under "the crux of the matter" is wrong. By only measuring the x or z axis you cannot distinguish between a classical system with hidden variables and a quantum system. One has to measure at 45 degrees also. The diagram is right, the description is wrong. --Jules — Preceding unsigned comment added by 83.82.131.247 (talk) 13:32, 23 October 2015 (UTC)

'EPR paper' section[edit]

It quotes some 'Manjit Kumar' who directly contradicts basis of quantum mechanics.

<quote>"According to Heisenberg's uncertainty principle, it is impossible to measure both the momentum and the position of particle B exactly. However, according to Kumar, it is possible to measure the exact position of particle A. By calculation, therefore, with the exact position of particle A known, the exact position of particle B can be known. Also, the exact momentum of particle A can be measured, so the exact momentum of particle B can be worked out."</quote>

It is completely outragious to insert ref of unknown author. It should be removed and whole section should be rewritten. In fact, whole article needs to be rewritten. — Preceding unsigned comment added by Ikshvaaku (talkcontribs) 15:22, 5 August 2015 (UTC)

Manjit Kumar was inserted by User:Myrvin on 9 March 2011. As far as I understand, these Kumar's words do not add anything to the EPR paper, and probably are not intended to add, but only to popularize. Thus, on one hand, Kumar "directly contradicts basis of quantum mechanics" no less no more than EPR do; and on the other hand, there is no need to quote him in the article. For a reader that needs such a popular presentation, Kumar's book may be cited in Sect. 8.2 "Books". Boris Tsirelson (talk) 19:41, 5 August 2015 (UTC)

Sorry, I meant to put this somewhere else, but I do not know how to delete this.

External links modified[edit]

Hello fellow Wikipedians,

I have just added archive links to one external link on EPR paradox. Please take a moment to review my edit. If necessary, add {{cbignore}} after the link to keep me from modifying it. Alternatively, you can add {{nobots|deny=InternetArchiveBot}} to keep me off the page altogether. I made the following changes:

When you have finished reviewing my changes, please set the checked parameter below to true to let others know.

Question? Archived sources still need to be checked

Cheers.—cyberbot IITalk to my owner:Online 09:20, 27 February 2016 (UTC)

The EPR paradox and gravity[edit]

We now know that the speed of gravity, usually is close to the speed of light in the void (classical void) but in the real world occur disturbances because complex arrangements of matter, interlink particles in ways that cause "cohesion distortions". Gravity is not a fundamental force, the "graviton" is simply the superluminal "briefion" that connects briefly any particle, not necessarily only parts of the same compound particle. The graviton/briefion is nothing other than any virtual boson (can also be individual particle) of the other three fundamental forces• the gravitational field is a compound statistical mechanism of the electroweak gauge field and the strong/chromodynamic gauge field while the two interact indirectly (not as a first step of a feynogram [Feynman diagram] but as a further step, thus intermediate steps are required, and that constitutes gravity so weak, for it's only a secondary statistical effect of the interaction of the electroweak gauge field with the strong/chromodynamic gauge field inside the Higgs connection field) through the Higgs connection field. In huge accumulations of matter, statistically few entanglements occur, the actual entanglements are not enough to justify gravity, but we have to calculate the infinite virtual particles created using as a measure of time the ultimate Planck sequence. That infinity becomes renormalized due to the curvature of spacetime that doesn't allow infinite perfect alignments when relativistically observed at Planck sized microholograms (ultimate quantization of spacetime). Thus a non infinite amount of entanglements occurs. These entanglements transfer instantaneously quantum information, but the electroweak gauge field and the strong/chromodynamic gauge field continue to transfer information at luminal (thus not instantaneous) speed. All particle arrangements should constantly lose energy toward nothingness, because almost all virtual particles dissapear without being materialized (objectified). Gravity is the mechanism that maintans the overall energy (although no gravitational system is closed, and all lose energy towards the Universe; even the Universe isn't a closed system inside the Megaverse, and becomes so diffused with the passage of time so it reaches the upper limit of quantum decohesion, thus then the virtual particles are compelled to become actual [materialized/objectified] to fill the gap, this event is a Big Bang without singularity, and it occurs when entanglements are no longer possible) through the Higgs connection field, and brings matter closer to the center of gravity, in order energy is maintained.
