a particle within a box seems to “disappear” at a certain instant – leaving behind only its bare nonlocal properties – and then to “reappear” to in another place and re-assume them. Even within the well-known multitude of earlier quantum paradoxes, this evolution is extremely counterintuitive. It is made possible only due to the novel inclusion of tunneling within the pre- and post-selected system....Notice that the “−1 particle” should not be confused with an anti-particle. In contrast to the latter, which differs from its particle only with charge, a “−1 particle” is unique in that all its properties are negative when probed by weak measurement.The Case of the Disappearing (and Re-Appearing) Particle
a negative weak value suggests an effective interaction with a minus sign. The particle therefore effectively behaves as if all its properties (such as mass and momentum) are negative, thereby termed Nega-particle....Perhaps “superposition” is actually a collection of many ontic states (or better, two-time ontic states45),Nonlocal Position Changes of a Photon Revealed by Quantum Routers
But this is wrong from the beginning because in electromagnetic theory, wave property are electric and magnetic fields. They are complementary to the number of photons. You can never say that the theory of photon has definite electric and magnetic field because the two things don't commute. In fact the electric and magnetic field, which are the wave properties, they're collective properties of many many anti-number of photons. It's the wrong idea to say that I connect the wave property with the theory of photon. This is not true. So therefore, in the same token, we must realize that the so-called wave property of the electron are only properties of entanglement. We should never associate a wave property to a single electron....Each electron knows that the two slits are open...each electron must know that the two slits are open. The only way to explain this is to say that it's also a wave, that each electron goes through both slits....The difference between the Heisenberg equation of motion and classical equation of motion is that quantum mechanically the dynamics is non-local. And because of that we can explain what's happening in two slit experiments, not by saying the particle is a wave, but by saying that the particle has properties; their equation of motion depends non-locally on whether the double slit is open or not. Georges Lochak (pdf) response on de Broglie-AharonovAharonov on weak measurements
So imagine that we have a non-local interaction. Then I do something here, the particle there, suddenly it feels very quickly an effect. So we've shown that the only way quantum mechanics allows this to occur is because this thing that is affected in the particle is completely uncertain. There is no way to signal that the change. It's non-local but causality is preserved.
Aharonov interview on non-local Aharonov-Bohm effect
In fact, they present a straightforward realization of an entity we term counter-particles, namely pre-and post-selected states acting as if they have negative physical variables such as mass and energy....These in turn lead to the novel concept which merits further study, namely counter-particles with negative weak valueshttps://www.researchgate.net/publication/326179877_Extraordinary_interactions_between_light_and_matter_determined_by_anomalous_weak_values
accompanying particles with positive weak values, together obeying the familiar conservation laws.
By applying post-selection to the measurements of the probe photon, Aharonov and Vaidman showed, one could discern a shutter photon in a superposition closing both (or indeed arbitrarily many) slits simultaneously. In other words, this thought experiment would in theory allow one to say with confidence the shutter photon is both “here” and “there” at once. Although this situation seems paradoxical from our everyday experience, it is one well-studied aspect of the so-called “nonlocal” properties of quantum particles, where the whole notion of a well-defined location in space dissolves.
suggests a new and extraordinary vision of the underlying processes involved in the nonlocal existence of quantum particles. Through the lens of the TSVF, Elitzur says, this flickering, ever-changing existence can be understood as a series of events in which a particle’s presence in one place is somehow “canceled” by its own “counterparticle” in the same location. He compares this with the notion introduced by British physicist Paul Dirac in the 1920s who argued particles possess antiparticles, and if brought together, a particle and antiparticle can annihilate each other. This picture at first seemed just a manner of speaking but soon led to the discovery of antimatter. The disappearance of quantum particles is not “annihilation” in this same sense but it is somewhat analogous—these putative counterparticles, Elitzur posits, should possess negative energy and negative mass, allowing them to cancel their counterparts. So although the traditional “two places at once” view of superposition might seem odd enough, “it’s possible a superposition is a collection of states that are even crazier,” Elitzur says.
secrets of weak measurements
There's lots of great visuals to explain the particulars of quantum measurement secrets. There is a hilarious quote of Willis Lamb teaching the "psi" symbol of the wavefunction saying,
"don't worry what this means, you'll get used to it."As I watch - then I'll add more vids to this subject here.
What's the mind-boggling implication of the "weak measurements"? de Broglie and Bohm have been proven correct! The "wave function" is not just a mathematical abstract - at least not in the "noncommutative phase" between the collapses of the wave function.
In other words the non-local ether is being demonstrated in real time in the lab - through the double slit experiment.
So here is the teacher of Jeff Lundeen - Steinberg - on weak measurements

Avshalom Elitzur, My Future Engraved on Stone: Quantum Measurements that Seem to Undermine Becoming
Too Beautiful Not to be True (TedX)Aharonov’s proposal is that information about the future comes back and affects the present. “If two quantum particles from the same situation behave differently in the future, perhaps nature is trying to tell us there was a difference between them − but that this difference is not in the past, but in the future.” Or to put it more baldly: the future affects the present.
But in Aharonov’s new formalism, uncertainty is the price we pay for ensuring that information coming back from the future to the present cannot create a paradox. “It turns out,” says Aharonov, “that the only consistent way for something to come back from the future without paradoxes is to have uncertainty.”

Modification of "Counterfactual communication protocols" which makes them truly counterfactual (pdf)
Abstract: Possibility to communicate between spatially separated regions, without even a single photon passing between the two parties, is an amazing quantum phenomenon. The possibility of transmitting one value of a bit in such a way, the interaction-free measurement, was known for quarter of a century. The protocols of full communication, including transmitting unknown quantum states were proposed only few years ago, but it was shown that in all these protocols the particle was leaving a weak trace in the transmission channel, the trace larger than the trace left by a single particle passing through the channel. This made the claim of counterfactuality of these protocols at best controversial. However, a simple modification of these recent protocols eliminates the trace in the transmission channel and makes all these protocols truly counterfactualhttp://ecoechoinvasives.blogspot.com/2017/10/the-secret-of-time-and-theory-of.html
A year ago - I blogged on the same topic.
