NO they do not, and please cite if you feel this is so. Not serious scientists.
I read a lot, but you seem to fail to be current on current research on Quantum Mechanics.

Why delayed choice experiments do Not imply retrocausality
Why delayed choice experiments do Not imply retrocausality by David Ellerman
Abstract
Although retrocausality might be involved in quantum mechanics in a number of ways, the focus here is on the delay-choice arguments popularized by John Archibald Wheeler. There is a common fallacy that is often involved in the interpretation of quantum experiments involving a certain type of separation such as the: double-slit experiments, which-way interferometer experiments, polarization analyzer experiments, Stern-Gerlach experiments, and quantum eraser experiments. The fallacy leads not only to flawed textbook accounts of these experiments but to flawed inferences about retrocausality in the context of delayed choice versions of separation experiments.

1 Introduction: retrocausality in QM
There are a number of ways that the idea of retrocausality arises in quantum mechanics (QM). One way, which is analyzed here, is the argument largely due to Wheeler [
19] that delayed-choice experiments reveal a type of retrocausality.
There is also the
two-vector approach to QM pioneered by Aharonov et al.:
in which a quantum system is described, at a given time, by two (instead of one) quantum states: the usual one evolving toward the future and the second evolving backwards in time from a future measurement [
1, p. 1].
Cramer’s [
4] transactional interpretation of QM also involves the idea of a second wave travelling backwards in time. The idea of QM as involving a wave travelling backwards in time goes back at least to Arthur Eddington’s Gifford Lectures in 1927:
The probability is often stated to be proportional to ψ2" role="presentation" style="box-sizing: border-box; display: inline-table; line-height: normal; letter-spacing: normal; word-spacing: normal; overflow-wrap: normal; white-space: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 0px; min-height: 0px; border: 0px; padding: 0px; margin: 0px; position: relative;">ψ2ψ2, instead of ψ" role="presentation" style="box-sizing: border-box; display: inline-table; line-height: normal; letter-spacing: normal; word-spacing: normal; overflow-wrap: normal; white-space: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 0px; min-height: 0px; border: 0px; padding: 0px; margin: 0px; position: relative;">ψψ, as assumed above. The whole interpretation is very obscure, but it seems to depend on whether you are considering the probability after you know what has happened or the probability for the purposes of prediction. The ψ2" role="presentation" style="box-sizing: border-box; display: inline-table; line-height: normal; letter-spacing: normal; word-spacing: normal; overflow-wrap: normal; white-space: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 0px; min-height: 0px; border: 0px; padding: 0px; margin: 0px; position: relative;">ψ2ψ2 is obtained by introducing two symmetrical systems of ψ" role="presentation" style="box-sizing: border-box; display: inline-table; line-height: normal; letter-spacing: normal; word-spacing: normal; overflow-wrap: normal; white-space: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 0px; min-height: 0px; border: 0px; padding: 0px; margin: 0px; position: relative;">ψψ-waves travelling in opposite directions in time; one of these must presumably correspond to probable inference from what is known (or is stated) to have been the condition at a later time [
6, fn. pp. 216–217].
Finally the idea of retrocausality might arise when space-like separated entangled systems are viewed from different inertial frames of reference. Abner Shimony popularized the idea of “peaceful coexistence” [
17, p. 388] in spite of the “tension” between QM and special relativity.
In order to explore further the tension between quantum mechanics and relativity theory, let us consider an experimental arrangement in which [system 1] and [system 2] are tested by observers at rest in different inertial frames, and suppose that the tests are events of space-like separation. If the reduction of ψ" role="presentation" style="box-sizing: border-box; display: inline-table; line-height: normal; letter-spacing: normal; word-spacing: normal; overflow-wrap: normal; white-space: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 0px; min-height: 0px; border: 0px; padding: 0px; margin: 0px; position: relative;">ψψ is to be interpreted causally, then which of the events is the cause and which is the effect? There is obviously no relativistically invariant way to answer this question. It could happen that in one frame of reference the testing of [system 1] is earlier than the testing of [system 2], and in the other frame the converse is the case [
17, p. 387].
If a measurement of system 1 was taken as the “cause” and the reduction of system 2 the “effect” then in certain inertial frames the effect would precede the cause. This might be interpreted as a type of retrocausality or rather as a type of causal connection where the usual notions of “cause” and “effect” do not apply. As Shimony put it:
The wiser course is to say that quantum mechanics presents us with a kind of causal connection which is generically different from anything that could be characterised classically, since the causal connection cannot be unequivocally analysed into a cause and an effect [
17, p. 387].
These other ways in which retrocausality might arise in QM are mentioned solely to emphasize that this paper is
only concerned with Wheeler’s delayed-choice arguments."
It has been shown that the arrow of possibly may be reversed in QM. but it has not been falsified nor demonstrated.
