One of the common assumptions about some of the ‘weirdest’ aspects of quantum phenomena, is that we don’t need to be concerned with it, since it happens in the realm of the very, very, astonishingly small.
Our everyday life experience tells us that macroscopic systems obey classical physics, and we’ve even received reassurances from brilliant physicists that we need not concern ourselves with the possibility of quantum effects in daily life. It’s understandable that we then naturally expect that quantum mechanics must reproduce classical mechanics results in the macroscopic range–which is known as “the correspondence principle,” that physicist Niels Bohr established in 1920. Proponents of this premise have presumed for the past century that any transition from quantum mechanics to classical mechanics operates according to a kind of coarse-graining mechanism, whereby measurements performed on macroscopic systems that have limited resolution, and are unable to resolve individual microscopic particles will behave classically.
As discussed in my book, Quantum Jumps: scientists now confirm we can see quantum phenomena at macroscopic scale! “It is amazing to have quantum rules at the macroscopic scale. We just have to measure fluctuations, deviations from expected values, and we will see quantum phenomena in macroscopic systems”
How Quantum Correlations Can Survive
Researchers Miguel Gallego (University of Vienna) and Borivoje Dakić (University of Vienna and IQOQI) were surprised to discover that quantum correlations survive in the macroscopic limit when correlations are not independent and identically distributed (IID) at the level of microscopic constituents.
This idea of independent and identically distributed (IID) is the key here, since it is often presumed to be generally true in experimental laboratory settings. When quantum measurements are taken and calculated for the corresponding correlations, experimental designs typically involve a large number of repetitions, since the key assumption is that each run of the experiment must be repeated under exactly the same conditions, yet independently from other experimental runs. Experiments are designed with the idea in mind that they ensure that each quantum random “coin toss” is fair and unbiased, so the ratio of “heads” to “tails” comes out evenly, with either “heads” or “tails” expected 50% of the time.
As it turns out, this assumption, that plays such a pivotal role in the expectation that there exist only classical physics happening past some macroscopic limit. What these recent research results show is that what is really going on is that macroscopic groupings of clusters of quantum particles that are “coarse-grained” together interact with each other, with Borivoje Dakić stating:
“The IID assumption is not natural when dealing with a large number of microscopic systems. Small quantum particles interact strongly and quantum correlations and entanglement are distributed everywhere. Given such a scenario, we revised existing calculations and were able to find complete quantum behavior at the macroscopic scale. This is completely against the correspondence principle, and the transition to classicality does not take place”
What Are the Implications?
While we have long presumed the wide, wonderful, weird world of quantum physics to operate either alongside or within the classical realm, the real truth of the matter is that we’re seeing ever-increasing evidence to suggest that classical theory and physics might best be viewed as a special case within the bigger quantum reality.
By appreciating the possibility that quantum logic is primary in the natural world, we see how humanity stands to benefit from embracing the innate quantum logic implicit in everything. We can thus envision how the addition of quantum theory ushers in a new view of all areas of study, including: biology, psychology, sociology, cosmology, statistics, and history. The idea that quantum phenomena occur at all levels—not merely at microscopic quantum levels—indicates we are able to develop a more functionally predictive and naturally based quantum perspective that promises to completely revise our worldview.
