How can she possibly deny that when the evidence is undeniable?

That is not surprising at all. That’s like saying laying off the conspiracy theory conventions for a while reduces your belief in conspiracy theories.

That may not be the correct way of saying it. You can equally explain the data by phrasing it, “when the photon remains a wave, the which path information is nonrecoverable.”

Moreover, it's observed that the apparent retroactive action vanishes if the effects of observations on the state of the entangledsignal and idler photons are considered in their historic order. Specifically, in the case when detection/deletion of which-way information happens before the detection on D0, the standard simplistic explanation says "The detector Di, at which the idler photon is detected, determines the probability distribution at D0 for the signal photon". Similarly, in the case when Dprecedesdetection of the idler photon, the following description is just as accurate: "The position at D0 of the detected signal photon determines the probabilities for the idler photon to hit either of D1, D2, D3 or D4". These are just equivalent ways of formulating the correlations of entangled photons' observables in an intuitive causal way, so one may choose any of those (in particular, that one where the cause precedes the consequence and no retrograde action appears in the explanation).

The total pattern of signal photons at the primary detector never shows interference (see Fig. 5), so it is not possible to deduce what will happen to the idler photons by observing the signal photons alone. In a paper by Johannes Fankhauser, it is shown that the delayed choice quantum eraser experiment resembles a Bell-type scenario in which the paradox's resolution is rather trivial, and so there really is no mystery. Moreover, it gives a detailed account of the experiment in the de Broglie-Bohm picture with definite trajectories arriving at the conclusion that there is no "backwards in time influence" present.[23] The delayed-choice quantum eraser does not communicate information in a retro-causal manner because it takes another signal, one which must arrive by a process that can go no faster than the speed of light, to sort the superimposed data in the signal photons into four streams that reflect the states of the idler photons at their four distinct detection screens.[note 2][note 3]

But more importantly, you will get the same results regardless of whether a human being is there to observe it. It’s the detection of the photon (by way of interacting with the photon detector) that matters, not whether there is a person there to observe the detection.

Try it. Just change an environment variable, then run up -d and you’ll see.

hperrin , to Selfhosted in Jellyfin | "We are pleased to announce the latest stable release of Jellyfin, version 10.9.0!"

You don’t actually need to run down first. Just a docker compose pull if you haven’t made any changes, then docker compose up -d will restart whatever needs to be restarted.

Yay Jellyfin! What an awesome app!

Hi neighbor. I’m in Temecula.

hperrin , to No Stupid Questions in Did the premise of an entity approaching you only when it's not being viewed originate with Doctor Who's Weeping Angels?

Yeah, I guess in my statement I should have said “unless” instead of “until”, because it’s not time dependent. But it’s still the act of measurement, not the act of a conscious person looking at that measurement, that causes the collapse of the wave function.

hperrin , to No Stupid Questions in Did the premise of an entity approaching you only when it's not being viewed originate with Doctor Who's Weeping Angels?

“Observation” in quantum mechanics doesn’t mean a person looking at them, it means taking a measurement, which involves interacting with the particles somehow. It’s that interaction that causes the particles to behave differently. In other words, photons behave as a wave (moving according to a wave function) until another particle interacts with them, at which point they behave as a particle (moving in a straight line). See the various different double slit experiments for evidence of this.

A hero.

Calm down, Satan.

hperrin , to Linux in Are we (linux) ready for Arm devices?

I’m more excited for Linux on RISC-V, but yeah, Arm is neat.

hperrin , to Ask Lemmy in Do adults benefit from flouride?

Yes, the benefit doesn’t vary by age. Flouridated water prevents cavities throughout your life.
