Physicists measured Earth’s rotation using quantum entanglement

Physicists measured Earth’s rotation using quantum entanglement! Since when has classical wave interference become “Quantum interference”?

The experimental setup as described in the original Silverstein et al 2024 experiment is fairly complex compared to the original Sagnac version. However complexity here does not mean it is no longer a basic time of flight Sagnac interferometer with observations consistent with a classical wave only model of light.

I’ve seen similar flights of fantasies of supposed ‘proof of QT’ from other very well known “Quantum” experiments. For instance the Kim et al 1999 Delayed Choice quantum eraser experiment. Where on analysis they had only confirmed the classical model of light. Where light is a wave only and not a photon. 

The technique is also used here. QT ‘researchers’ also have made the experiment as complex as possible so as to disguise the fact that the experiment can still be explained classically without referring to relativity or QT. I have comprehensively dissected Kim et al’s Delayed choice experiment setup and shown how adding complexity is also used to prove Quantum fantasies, at this following link http://physicsexplained.blogspot.com/2015/11/the-main-illustrationbelow-is-schematic.html

The same applies to this current 2024 experiment. They manage to pull off this Quantum trick by pretending that somehow ...classical polarised states of wave only light and wave interference are signs of the light being a particle and subject to quantum nuttiness!! 

The fact is that in this experiment there is still only just a path difference detected. And it is detected, as usual for any Sagnac interferometer, via interference patterns. Nothing more. They even admit this is all thats observed. The sleight of hand here is QT dogma at its greatest. They pretended that classical wave interference, observed and documented for centuries by Young and others... is somehow now called “Quantum Interference”

Laughable nonsense as usual from establishment physicists.

Three Photon Quantum interference and Harmonic of single energy scales

 Quantum computers have been “just around the corner” for 3 decades or more. And will never be realised. They are science fiction fantasy based on an imaginary magic pseudoscience called Quantum wave particle duality. Quantum “theorists” seem to publish almost daily their misunderstandings of the classical interference effects of wave only Electromagnetic radiation. Below is a link where once again quantum theorists have misunderstood classical resonance in atoms. Because in truth Atoms are just classical harmonic oscillators and will produce a specific range of harmonics and sub harmonics from just one source fundamental wavelength. https://www.sciencedaily.com/releases/2024/04/240423113051.htm

And from another paper on imaginary 3 photon interference I’ve quoted below some text from another paper on imaginary 3 photon quantum effects. Essentially the researchers have once again misunderstood classical wave only interference effects and harmonic oscillators. And pretended these basic classical effects are spooky quantum magic! https://arxiv.org/pdf/2307.02189

“A high-quality single-photon source based on a semiconductor quantum dot [27] embedded in an open microcavity is used to deterministically produce single photons that are converted to the telecommunication band with a quantum frequency converter [28, 29]. These single photons are deterministically demultiplexed into six indistinguishable singlephoton sources [30, 31], which are manipulated in a fully programmable photonic chip [32]. Heraled by the detection of four output spatial modes with high-efficiency single-photon detectors”

This quote above is an experimental description quoted directly from the opening page of the above linked arxiv paper. And is essentially describing a classical interference effect. Nothing to do with imaginary quantum effects. 

There is no need to invoke quantum theory to describe classical wave theory of light. Here below is my classical translation of the above “Quantum” papers quoted text: 

“A (low level) light source produces wave emr that is then converted into different wavelengths of emr following centuries old knowledge of resonance and harmonic oscillators. Wavelengths which are then made to interfere with each other in what is called classical wave interference. And the resulting wavelength radiation is then detected at various detectors where wave radiation is absorbed by the detector atoms. Each atom acting sort of like a atom sized capacitor which absorbs discreet amounts of incident wave radiation and releases it in pulses to be amplified and sent to the detector hardware using the “electron” cascade effect. And misconstrued as some sort of magical spooky quantum action at a distance effect.“

The following link is a graphic description of how wave radiation and atom absorption can model imaginary ‘single double or triple photon’ quantum detection as a purely classical effect: https://www.youtube.com/watch?v=8H9kx9_sQYA

And regarding the process cited in these papers as “quantum frequency convertors” and the supposed “surprising” harmonic order observed in SPE’s indicating a energy scale in the Science daily press release cited above.  Once again the classical nature of atoms as harmonic oscillators has been ignored in favour of quantum spookiness. 

To get the correct explanation using a classical wave only model of atoms and light that does not involve spooky quantum nonsense look to this following paper on Harmonic and sub harmonic wavelengths generated from a single fundamental wavelength in Hydrogen atoms: https://vixra.org/author/p_g_vejde

No need for any quantum magic. Any researchers or institutions wishing to try to harness classical wave interference correctly to try and exploit any possible advances in computing that classical interference could offer to computing had best stop wasting their time and budgets looking for mythical quantum dragons and spooky entangled angels. And hire me to explain how quantum theory has misled research into theoretical physics for more than a century ever since Neil’s Bohr published his misguided Electron shell model in the early 20th C. The fact is that all observed energy levels in all atoms can be modelled succesfully  using a wave only classical model. No imaginary electron shells or photons needed.

James Webb observations contradict Big Bang Theory predictions

 Getting closer now to the JWST observing galaxies in a new deep field survey that were not predicted explained or even expected from the Big Bang Theory.

But how will the BB theorists get out of admitting their theory and its predictions screwed up (again)?

Brian Cox has led the way for the new revisionist version of BBT and has explained on his BBC religious program “Universe” exactly how the new upcoming JWST data and current data on large scale structures that until now cannot be explained by the BBT, can be made consistent with current dogma.

Apparently Brian and his fellow BBT fantasists are going to pretend the galaxies and large scale structures  that shouldn’t be there in the so called “early universe” predicted by these BBT nutters (and soon to be observed by the JWST) are “echoes” of the previous Big Bang.

And in an extra footnote to the whole BBT hoax here is a quote below from the historical record showing Hubble himself didn’t think redshift was due to expansion. Because in 1929 Hubble knew “expansion” was not real. He just couldn’t attribute it to a failure of Einsteins photon model. Because Albert was just too famous to challenge having just won the Nobel prize for pretending photons could not lose energy over distance. https://www.nobelprize.org/prizes/physics/1921/summary/

“Hubble concluded that his observed log N(m) distribution showed a large departure from Euclidean geometry, provided that the effect of redshifts on the apparent magnitudes was calculated as if the redshifts were due to a real expansion. A different correction is required if no motion exists, the redshifts then being due to an unknown cause. Hubble believed that his count data gave a more reasonable result concerning spatial curvature if the redshift correction was made assuming no recession. To the very end of his writings he maintained this position, favouring (or at the very least keeping open) the model where no true expansion exists, and therefore that the redshift "represents a hitherto unrecognized principle of nature". This viewpoint is emphasized (a) in The Realm of the Nebulae, (b) in his reply (Hubble 1937a) to the criticisms of the 1936 papers by Eddington and by McVittie, and (c) in his 1937 Rhodes Lectures published as The Observational Approach to Cosmology (Hubble 1937b). It also persists in his last published scientific paper which is an account of his Darwin Lecture (Hubble 1953).”

Delayed Choice Classical Eraser Experiment

The main illustration above is a schematic of the Delayed choice quantum eraser experiment. (Kim et al 1999)

The coincidence rates compiled from the 5 detectors can be explained by a classical model. By assuming the following: The light arriving at D0, D3, and D4 is vertically and horizontally polarized. Alternating between the two states once per frequency cycle of the light beam. (Circular polarization is one possibility). Each polarized state has its own associated interference pattern. The image on the movable detector plane of D0 is of two, overlapping, out of phase interference patterns rapidly oscillating between each other. Once per frequency cycle of the light. The overall superimposed image of the two overlapping patterns, over time, is of no overall interference pattern. 

The lightbeams arriving at D1 and D2 have been additionally plane polarized. One vertical one horizontally. This also puts the horizontal out of phase by half a cycle, temporaly, from the vertical.Thus essentially, the detectors D1 and D2 each only recieve half of the light pulse that leaves the beam splitter. Either vertical or horizontally polarized. This allows detectors D1 and D2 to only trigger light detections coincident with a light detection from only one of the two rapidly oscillating interference patterns at D0. 

Detectors D3 and D4 on the other hand, receive both vertical and horizontal plarized light. And thus detectors D3 and D4 have coincident detections with both overlapping oscllating interference patterns at D0.

This is what is observed in the Kim et al experimental setup.

There is no need for a counterintuitive "quantum erasure". The observed coincidence rates are explained simply by polarization states of light incident on the 5 detectors.

(Sept2021 postscript: Ive noticed from some comments that a more detailed explanation is needed. Here is additional information: This experiment is as easily explained using classical wave only theory and polarised states. Light leaves the double slit/BBO/Glan Thompson prism with alternating polarity between vertical and horizontal.

(This is essentially circular polarised light. Because if the two beams going to detector zero werent alternating between horizontal and vertical polarised light each cycle and instead were just two same plane polarised beams as some pretend, then the two phase shifted interference patterns and diffraction patterns observed at detector 0 would not be possible) 

Detectors 1 and 2 get two light beams each. One beam reflected twice which means the light incident on each detector is a combination of left and right hand circular polarised light beams. Which can only result in plane polarised light hitting each detector 1&2.  (Note that if one combines a left handed circular polarised beam with a right handed circular polarised beam the combined result is a beam that alternates between two opposing polarised states and plane polarisation each cycle. That is effectively plane polarised light.

Because the D1 beams undergo opposite reflections at the mirrors and beam splitters from the D2 beams...the two detectors 1&2 thus also each receive polarised light that is phase shifted by half cycle from the other. Ie..vertical and horizontal respectively.

Detectors 3 and 4 only get one beam reflected once, each.(The one reflection restores the polarity of the beams from orthogonally polarised circular light leaving the BBO/G-T prism setup back to identically circular polarisation. Which means they get the same phase light as that arriving at detector zero. 

The resulting polarised states mean D1&2 each only “observe at Detector Zero” via the coincidence counter two seperate phase shifted interference patterns from the other .And detectors 3 & 4, having the same incident polarised light as detector zero , observe diffraction patterns via the coincidence counter. 

No spooky quantum mumbo jumbo  maths needed to explain this experiment.

And finally to address claims that the Glan Thompson prism used in the experiment cannot send circular polarised light beams to the rest of the experimental setup. Critics cite evidence showing that similar birefringement mediums such as calcite crystals split the beam into two orthogonally plane polarised beams. And using plane polarisation filters they show how the two exiting light beams must be only plane polarised. As a plane polarised filter put over the two images only allows through one of the two images coming through the calcite filter. 

However this ignores the fact that a vertically plane polarising filter allows through not just vertical polarised light...but all angles except horizontal. So for instance around 45% of the light polarised at 45 degrees to vertical is let through a vertically polarised filter. The more the polarisation angle of the light deviates from vertical the less light is let through etc.

In other words a circular polarised beam will be split into two polarised beams by the crystal one beam preserving majority vertical, one majority horizontal. But still containing elements of all other angles of polarisation. And thus the circular polarisation of the beam is preserved.

Proof of this is available at any demonstration showing unpolarised light going through two plane polarised filters. Position both filters at vertical and all vertically polarised light from a source goes through, and blocking all horizontal polarised light. Turn one filter slowly to horizontal and the light coming through decreases to zero as both vertical and horizontal light from the source are now blocked. Light coming through doesn’t immediately decrease to zero as soon as the two polarised filters angle starts to diverge. It is an incremental decrease. Proving a plane or linear polarising filter still lets through almost all angles of polarisation. But at different amplitudes. 

This is how one can explain how two circular polarised light beams can appear as two plane polarised beams exiting the Glan Thompson prism.
