Quantum Eraser Rewrites the Past

I'm no physicist, I don't understand this, but if it means what I think it means if we use this experiment as the determining variable in some process couldn't we use it like the alien's power in Edge of Tomorrow?

In other words if we can change the outcome of an experiment retroactively we can use that to communicate with our past selves, which apparently means we never send the message back but rather simply receive a message which changes what we do therefore that outcome never occurs.

So in any war we can win we will win because we retroactively prevent any outcome in which we don't.

No information is preserved when acting on quantum entangled bodies. So all you can achieve with it is bound to produce random noise.

That seems to be the rule, no FTL or retroactive quantum interaction is known to transfer information.

Noise to me means that there is no pattern. But the screen registers a pattern in relation to the paired photons. This is even repeatable. The pattern shows an interference pattern when the photons activate the sensors that are not slot specific and no interference pattern when the sensor measuring the paired photon is slot specific.

If the pair is entangled then the polarization of the photon could alter the polarization of it's pair thereby altering the pattern on the screen. If there is no entanglement then altering the paired photon should have no effect with what shows up on the screen. The polarization would be a consequence of the mirrors that are used on the paired photon.

I was talking about ALL quantum phenomena that involve entanglement, not only interference.

You clearly took literally what I said and applied it to your skewed understanding of the video.

That said you're wrong even in this narrow interpretation.
An interference pattern is random in that there is a broad area of probability where a particle can land, as opposed to a predictable radius or a single point. This is in turn caused by the random noise of the quantum interactions.

This video is about quantum retroaction basics (not quantum randomness basics, though they might get there in their current series), I recommend their channel because they provide some of the deepest glances from the surface out of all pop-scientific contributors on youtube in a way that respects the intellect of the viewer.

I remember you having some alternate theories about relativity, perhaps your confusion stems from your personal misconceptions about randomness and quantum theory.

1) I fully understand this. The fact that I didn't elaborate on this does not mean that I didn't understand it.
2) The point is that there are variables that alter the probability wave. This variable seemingly reacts to the how the paired photon is being observed.

This is in turn caused by the random noise of the quantum interactions.

You just choose a weird phrasing.
Consider a pitching machine that is designed to throw the ball in the same place. In actuality if you register where it lands on the other side the results will show a bunch of different spots where it actually hits. This is caused by other variables at play. The shape of the ball, wind, and physical differences within the machines shoot or even the vibration of the machine that caused the ejection point to change ever so slightly. You can call all of this 'random noise of physical world interactions' but that is just confusing and ignores the actual fundamental variables that may be contributing to this.

I remember you having some alternate theories about relativity, perhaps your confusion stems from your personal misconceptions about randomness and quantum theory.

Of course there seems to be a concept out that that doesn't align with standard physics and does not fit my pitching machine example. Their belief is that the randomness is actually a function of the quantum universe.

Science cannot prove randomness. If something seems random then it is likely we don't know the variables that are affecting the results. If you are talking about the probability wave... that is just a statistical formula in which to determine the end result of where each photon may land. It isn't enough to be considered a theory on how the position and trajectory of the photon is set and altered in order to make the wave.

There seems to be a lot of thinking in regards to the idea that the quantum world operating on the rules of random probability. I say that it does not and that the randomness is just a consequence of our lack of knowledge and understanding. It may seem like splitting hairs but this isn't the way physics has always been known to operate and we shouldn't look at it the other way.

I mean when some scientists have to question how the information in the photons are time traveling you should be wondering if the basis for their theory might be a little off.
