Yet another blow to scientific realism. There was another recently published paper that showed how macrorealism was violated. Entanglement has been
done with particle pairs but this experiment was done with a single photon.
An experiment devised in Griffith University’s Centre for Quantum Dynamics has for the first time demonstrated Albert Einstein’s original
conception of “spooky action at a distance” using a single particle.
In a paper published in the journal Nature Communications, CQD Director Professor Howard Wiseman and his experimental collaborators at the University
of Tokyo report their use of homodyne measurements to show what Einstein did not believe to be real, namely the non-local collapse of a particle’s
According to quantum mechanics, a single particle can be described by a wave function that spreads over arbitrarily large distances, but is never
detected in two or more places.
This phenomenon is explained in quantum theory by what Einstein disparaged in 1927 as “spooky action at a distance”, or the instantaneous non-local
collapse of the wave function to wherever the particle is detected.
These things have profound implications about the nature of reality and basically show materialism is dead. I’ll explain more in a minute but the
article went onto say.
“Einstein never accepted orthodox quantum mechanics and the original basis of his contention was this single-particle argument. This is why it is
important to demonstrate non-local wave function collapse with a single particle,” says Professor Wiseman.
“Einstein’s view was that the detection of the particle only ever at one point could be much better explained by the hypothesis that the particle is
only ever at one point, without invoking the instantaneous collapse of the wave function to nothing at all other points.
“However, rather than simply detecting the presence or absence of the particle, we used homodyne measurements enabling one party to make different
measurements and the other, using quantum tomography, to test the effect of those choices.”
“Through these different measurements, you see the wave function collapse in different ways, thus proving its existence and showing that Einstein was
Schrodinger also hated it because of what QM implied.
I don’t like it, and I’m sorry I ever had anything to do with it.
(Erwin Schrodinger talking about Quantum Physics)
QM basically destroys any materialist notion of reality. What it supports is what mystics, spiritualist, religions, Philosophers and some Scientist
have been saying for years. It’s Plato’s Allegory of the Cave or the Akashic Records. It’s Einstein even saying that separation from the whole is an
So what is this telling us?
What these things mean is that the reality we experience is just a local perception of “NOW” that’s just an illusion. The true nature of reality we
can’t seem to measure so we measure an aspect of our local environment. Many people mistake this local perception of “NOW” as being some sort of
objective reality when it’s not.
The wave function is real and I say nonphysical.
The wave-function is real but nonphysical: A view from counterfactual quantum cryptography
Counterfactual quantum cryptography (CQC) is used here as a tool to assess the status of the quantum state: Is it real/ontic (an objective state
of Nature) or epistemic (a state of the observer’s knowledge)? In contrast to recent approaches to wave function ontology, that are based on realist
models of quantum theory, here we recast the question as a problem of communication between a sender (Bob), who uses interaction-free measurements,
and a receiver (Alice), who observes an interference pattern in a Mach-Zehnder set-up. An advantage of our approach is that it allows us to define the
concept of “physical”, apart from “real”. In instances of counterfactual quantum communication, reality is ascribed to the interaction-freely measured
wave function (ψ) because Alice deterministically infers Bob’s measurement. On the other hand, ψ does not correspond to the physical transmission of
a particle because it produced no detection on Bob’s apparatus. We therefore conclude that the wave function in this case (and by extension,
generally) is real, but not physical. Characteristically for classical phenomena, the reality and physicality of objects are equivalent, whereas for
quantum phenomena, the former is strictly weaker. As a concrete application of this idea, the nonphysical reality of the wavefunction is shown to be
the basic nonclassical phenomenon that underlies the security of CQC.
Here’s another article:
Traveling without moving: Quantum communication scheme transfers quantum states without transmitting physical particles
This herein lies the crux of the matter. Some who support Copenhagen will say the wave function is a mathematical construct but this is because there
isn’t anything physical that can describe it. So it doesn’t really exist but they just need to ask is the wave function a nonphysical entity and
everything falls into place.
The nonphysical wave function is an entity of quantum states or information about every measured state that can exist. It’s the whole that we can’t
measure in it’s totality. So when we do measure it, we can only experience one quantum state because we can’t measure the totality of the wave
function. So we see what we call “matter” which illuminates these states within our environment.
So like I said, the mystics, Philosophers and Spiritualist have been right all along. It’s amazing that people like Plato and Parmenides could grasp
these things without the scientific knowledge we have today.
