Asking Robert Flack (and Yakir Aharonov's research group) about noncommutative antigravity via weak measurements

 

Hi Professor Flack: I have corresponded with Professor Basil J. Hiley several times in the past five years. I am wondering what the latest is with the argon weak measurement test for noncommutativity?  
 
 " for future experiments where we aim to measure the weak value of transverse momentum inside a matter-wave interferometer[23]." 
https://arxiv.org/pdf/2103.04756.pdf
Yakir Aharonov's weak measurement research group makes mention of antigravity. 
 
"In particular, this implies the possibility of gravitational repulsion rather than attraction within the weak reality. Moreover, not only the gravitational mass, but also the inertial mass will be shown to admit a negative sign."
Since Professor Hiley says this is a "new quality of energy" that could be used for engineering - do you think this could be the basis for antigravity?
thanks,

The issue of a repeatable experiment is challenged due to the noncommutativity that is nonlocal as the foundation of reality. 

"In light of this discussion, it seems that dynamical non-locality may be viewed as a forward-in-time manifestation of retrocausal phenomena within a two-time picture and vice versa."

 https://arxiv.org/pdf/2303.00701.pdf  

"This is made possible by exploiting sequential weak measurements, allowing to measure non-commuting observables in sequence on the same state, on each entangled particle....dynamical nonlocality seems to manifest the system’s dependence on future configurations in a
two-time picture." 

https://arxiv.org/pdf/2303.04787.pdf  

"Although, of course, some decoherence is induced on the measured entangled state, in the weak measurement framework the wavefunction does not (fully) collapse, allowing to measure non-commuting observables in sequence on the same quantum state [18] and, as a consequence, making it possible to extract information on the whole Bell parameter |S|
from each entangled pair measured." 

And so the antigravity resonance relies on meditation enabling a superluminal noncommutative signal not possible is external measurements: 

"this implies the possibility of gravitational repulsion rather than attraction within the weak reality. Moreover, not only the gravitational mass, but also the inertial mass will be shown to admit a negative sign." Quantum reality with negative-mass particles https://arxiv.org/pdf/2201.09510.pdf I have sent in a couple inquiries to the paper's authors to see if they think it is possible to resonate this gravitational repulsion but I doubt it. In meditation this is how it works though. thanks, drew 

 

 all the ‘action’ of quantum phenomena takes place in a pre-space,
the structure of which is described by the algebra. All we see is its projection
onto a space-time manifold. Thus the space-time manifold is not to be taken as
‘basic’. Rather it is something that is derived from the deeper and more basic
structure-process.
It is well-known that we cannot display quantum processes in a commutative
phase space because we are using a non-commutative structure. However this
does not rule out the possibility of representing quantum phenomena in terms
of a non-commuting phase space. In fact this has already been achieved through
the Moyal algebra [55], sometimes described as the deformed Poisson algebra.
This structure contains a non-commutative -product which gives rise to
a Moyal bracket, which can be used to produce an analogue of equation (4.4).
There also exists a symmetric bracket, the Baker bracket [42], which can be used
to produce an equation which is the analogue of (4.1). Thus these equations
seem basic to the type of non-commutative structures that we are using to
describe quantum phenomena.

 The resulting quantum force
(gradient of the quantum potential) is seen, in Bohmian theory,
as mediating the influence of the wave on the particle, guid-
ing it along its otherwise classical trajectory. In the Bohmian
interpretation, the quantum potential accounts for all quantum
phenomena. Moreover, the strength of the quantum potential
does not decay with distance, a property that accounts for the
nonlocality of quantum phenomena in the Bohmian perspec-
tive, and is also a necessary feature of the theory a la Bell’s
theorem [33, 34]....

 Since the effective mass squared term can be negative, not
only can the photon acquire a mass, but it might also be imag-
inary. This is compatible with the anticipated tachyonic be-
haviour of relativistic particles in Bohmian mechanics. While
this peculiarity is not in strict contradiction with standard
quantum mechanical observations–since the latter only deals
with expectation values incapable of revealing the superlumi-
nal behaviour [37]–the tachyonic Bohmian trajectories still
pose a conceptual difficulty if one wishes to interpret them
as physically real. We believe the present work provides a
viable interpretation of such difficulties, as we shall explain
in the next sections. Intriguingly, the relationship between
the effective mass and the quantum potential has been pro-
posed as an explanation for the anomalous photoelectric ef-
fect [43], whereby anomalous photoelectric emission and gas
photo-ionization by light has been observed for single photons
whose energy is lower than the work function of the material.
This effect provides an experimental hint at the existence of
the local mass and its effects. Just as the possibility of a neg-
ative mass particle ontology has inspired the theoretical in-
vestigations of this paper, the anomalous photoelectric effect
motivates us to define a framework for the direct measurement
of the local photon mass, and to compute its value for single
photons.

  locally superluminal or
locally massive photons is outside of its scope. However, us-
ing a theoretical framework which deals with individual quan-
tum events, the aforementioned peculiar qualities of a pho-
ton can be described and even measured in principle. For the
former we appeal to Bohmian mechanics, while the latter is
achieved using the language of weak values. Our construction
motivates novel opportunities for capturing phenomena that
were, until now, out of the experimentalist’s reach. Simulating
such an experiment with photons, not only do we find locally
massive particles of light, but they are also shown to exhibit
local tachyonic behaviour, which is perceived, in a boosted
frame of reference, as time-traveling particles. Surprisingly,
this does not pose a challenge to relativistic principles, as the
velocity we operationally define in a specific frame of refer-
ence is, in fact, a coordinate velocity which might exceed c.
This is consistent with the fact that the locally spacelike trajec-
tories cannot be revealed using strong measurements since no
information, which the expectation values of quantum observ-
ables could reveal, travels faster than c.

How the result of a measurement of a photon’s mass can turn out to be 100
Yakov Bloch1 and Joshua Foo

When the time component of the current is negative, the particle moves backwards in time. As a consequence, such particles might assume several
positions simultaneously and move faster than c.
