New research into light particles challenges understanding of quantum theory
Researchers at the University of East Anglia (UEA) have shown that when photons - the fundamental particles of light - are created in pairs, they can emerge from different, rather than the same, location.
The ground-breaking research could have significant implications for quantum physics, the theoretical basis of modern physics. Until now, the general assumption was that such photon pairs necessarily originate from single points in space.

So this research study got coverage in the popular science press.
Discovery of New Mechanism can Significantly Impact Study of Quantum Physics
So when it says "study of" - this actually indicates "meaning of " or "understanding of" - a significant impact to the basic understanding of quantum physics!
Now, the identification of a new delocalized mechanism shows that each photon pair can be emitted from spatially separated points, introducing a new positional uncertainty of a fundamental quantum origin.
What this is really indicating is the noncommutative origin of reality as the ether or protoconsciousness - called nonlocal quantum force.
Everything has a certain quantum ‘fuzziness’ to it, and photons are not the hard little bullets of light that are popularly imagined.

And I quote:
The introduction of the vacuum field as a means of energy transfer between separate optical interaction sites, extending beyond the usual constraints of the uncertainty principle.
And on the chirality of light as a self-amplifying energy:
Chiral discrimination can arise when the laser input has a circular polarization, if the particles are themselves chiral. Then, it emerges that the interaction between particles with a particular handedness is responsive to the left- or right-handedness of the light. The present analysis, which expands upon previous studies of chiral discrimination in optical binding, identifies a novel mechanism that others have previously overlooked, signifying that the discriminatory effect is much more prominent than originally thought. The new theory leads to results for freely-tumbling chiral particles subjected to circularly polarized light. Rigorous conditions are established for the energy shifts to be non-zero and display discriminatory effects with respect to the handedness of the incident beam. Detailed calculations indicate that the energy shift is larger than those previously reported by three orders of magnitude.

Nonlocalized Generation of Correlated Photon Pairs in Degenerate Down-Conversion (linked)allowing for each photon of the correlated pair to emerge from spatially distinct (and separated) points in space introduces a positional uncertainty of a fundamentally quantum origin. In the following analysis, utilizing a quantum electrodynamical (QED) approach cast in terms of virtual photon coupling [42], we fully account for both the localized and nonlocalized generation of correlated photon pairs.

The physical mechanism, which operates through virtual photon propagation, provides for photon pairs to be emitted from spatially separated sites of photon interaction; occasionally pairs are produced in which each photon emerges from a different point in space. The extent of such nonlocalized generation is influenced by individual variations in both distance and phase correlation.
