It appears from this that entanglement will become useful as we learnto work with it. This is an impressive result. It any thing, wehave a problem using the baggage of classical wordage to describe it. Toss all that out and we have partially bounded curvature behavingin a synchronized manner across possibly time and space.
This is the real beginning of research into photon behavior andstructure. For what it is worth, with my new metric it is possibleto precisely model the surfaces that form photons, at least intheory, although we are dealing with huge synchronized complexitythat interacts. In practice it will be about massive simulation andestablishing models for generated forms to allow us to get a handleon it.
Again it is a beginning.

To this end, theresearchers developed a new method for entangling single photonswhich gyrate in opposite directions. This result is a first steptowards entangling and twisting even macroscopic, spatially separatedobjects in two different directions.
The researchers at theVienna Center for Quantum Science and Technology (VCQ), situated atthe University of Vienna, and the Institute for Quantum Optics andQuantum Information (IQOQI) at the Austrian Academy of Sciences havewere able to get their pioneering results published in the currentissue of the renowned scientific journal Science.
Quantum physics isusually considered to be the theory of extremely lightweight objects,such as atoms or photons, or of exceptionally small units, namelyvery small quantum numbers. One of the most fascinating phenomena ofquantum physics is that of entanglement. Entangled quanta of lightbehave as if able to influence each other - even as they arespatially separated.
The question ofwhether or not entanglement is limited to tiny objects or very smallquantum numbers came up already in the early days of quantum physics.Now, the Vienna group has taken the first step for testing quantummechanical entanglement with rotating photons. To illustrate, aquantum mechanical figure skater would have the uncanny ability topirouette both clockwise and counter-clockwise simultaneously.
Moreover, thedirection of her rotations would be correlated with the twirls ofanother, entangled, skater - even if the two ice dancers whirl farremoved from each other, in ice rinks on different continents. Thefaster the two quantum skaters pirouette, the larger is the quantumnumber of their rotation direction, the so-called angular momentum.
"In ourexperiment, we entangled the largest quantum numbers of any kindof particle ever measured," declares Zeilinger with a wry smile.
Could quantum icedancers exist in reality?
It has been commonknowledge for about 20 years now that theoretically, there is noupper limit for the angular momentum of photons. Previousexperiments, however, have been limited, due to physicalrestrictions, to very weak angular momentum and small quantumnumbers. In the Vienna experiment, it is theoretically possible tocreate entanglement regardless of the strength of the angularmomentum or the scale of its quantum number.
"Only our limitedtechnical means stop us from creating entanglement with twistedphotons that could be sensed even with bare hands," statesRobert Fickler, the main author of the current Science publication.And so, the researchers have demonstrated that it is possible inprinciple to twirl entangled ice skaters simultaneously both inclockwise and counter-clockwise directions.
In practice, a numberof major challenges need to be addressed before such an experimentcan be realized with macroscopic objects.
From fundamentalresearch to technical applications
In addition to thefundamental issue of the limits of macroscopic entanglement, thephysicists address possibilities of potential applications. They are,for example, able to use the created photons for very precise angularmeasurements already at low intensities of light.
This feature is ofadvantage in particular when investigating light sensitive materials,as for example some biological substances. "The special featuresof entanglement provide the fantastic possibility to perform suchmeasurements from arbitrary distances and without any contactwhatsoever with the measured object, or even at a point in time thatlies in the future!" Fickler explains.
