Four Lasers over Mauna Kea (2014 Jun 23)

Explanation: Are lasers from giant telescopes being used to attack the Galactic center? No. Lasers shot from telescopes are now commonly used to help increase the accuracy of astronomical observations. In some sky locations, Earth atmosphere-induced fluctuations in starlight can indicate how the air mass over a telescope is changing, but many times no bright star exists in the direction where atmospheric information is needed. In these cases, astronomers create an artificial star where they need it -- with a laser. Subsequent observations of the artificial laser guide star can reveal information so detailed about the blurring effects of the Earth's atmosphere that much of this blurring can be removed by rapidly flexing the mirror. Such adaptive optic techniques allow high-resolution ground-based observations of real stars, planets, and nebulae. Pictured above, four telescopes on Mauna Kea, Hawaii, USA are being used simultaneously to study the center of our Galaxy and so all use a laser to create an artificial star nearby.

Sparkling at the edge of a giant cloud of gas and dust, the Flame Nebula, also referred to as NGC 2024, is in fact the hideout of a cluster of young, blue, massive stars, whose light sets the gas ablaze. Located 1,300 light-years away towards the constellation of Orion, the nebula owes its typical colour to the glow of hydrogen atoms, heated by the stars. The latter are obscured by a dark, forked dusty structure in the centre of the image and are only revealed by infrared observations.

*Radical Science Excerpt*
(Follow-up on the story involving Quantum Computations) - Quite literally, the research team over in Innsbruck have developed a way to utilize Quantum Entanglement's natural signal disruptions termed as "Quantum decoherence" or just "decoherence" (for short): This is when entangled particles fall out-of-sync with one another due to external (outside) forces, which usually come in the form of waves....This naturally causes signal disengagement between the two 'entanglement' particles - communication breaks down....This is bad, because the entire premise behind Quantum computation relies on the strange 'qubit' properties of particle spin, which range from +1/2 spin -1/2, 0, 3/2, 2, or a coupling of both (or multiple) spins at the same time....this goes well beyond the 'either or' classic 2-bit system of either 0 or 1.......What's the significance as it pertains to this experiment? Here's how theoretical q. physicists have approached the matter: USE that signal breakdown or 'decoherence'....rely on those errors, so that processors can safe guard against them....ultimately, predicting the fact that those errors may occur and develop specific 'topological' algorithms accordingly....
[Scenerio] Take the game of ping-pong for instance: It would be as if a single player were to strike the ping pong ball against a solid wall...The player wants the ball to ricochet back to HIM, at his same exact position....and let's say that in a perfect world...the ball actually does...the force exerted by that player (and the direction and momentum) is EXACTLY the same all the time...(and there is absolutely NO air resistance)....You could say that both the player AND the wall were exactly 'entangled' with each other (albeit newton's 3rd says that to colliding objects are of equal but opposite forces from one another, furthermore, each collision is completely elastic)....This is the entanglement system...tried and true 100% of the time....All of a sudden, some outside force (perhaps pressured sound waves or a gust of strong wind) 'interrupts' that perfect system: the ball goes into another trajectory, collides with the wall, then bounces back in a DIFFERENT direction, away from the pong player's initial position...Let's call this "decoherence" - this is what happens in nature constantly......So, at this point the entangled system before is NOW out-of-sync...The strategy is this: what if I could strategically copy that ping pong player and place him at the EXACT location of where I predict the ball is going to be....What if I could copy that player again, and place him at yet another position of where I KNOW the ball will fly?? What I've done is develop a specific pattern...and since these disruptions are predictable, I could apply the SAME kind of logic to the system, let's say, if the original pong player exerts an even stronger force...OR...swings the paddle in a different direction, sending the ball on a different and unique trajectory? As long as Newton's 3rd law holds true, then WHATEVER new information I induce on the entangled system, I'll always get the same end result, I predicted...and therefore, bypass whatever decoherence was imposed by 'external' (outside) forces....Even more so, I could use this pattern, and build other unique (more complex) patterns...the laws of quantum mechanics always, always holds true, no matter what....Thus, these operations are inherently 'linear' in nature.....
Now, of course, these kind of interactions are quite complex...So, complex that theoretical physicist have to employ other mathematical 'frameworks', namely topology...which underlays complex 3-dimensional space manifolds......Whatever the case may be, what you (and I) are witnessing is a foundational groundwork that is being developed...experiment after experiment...the fascinating aspect of this is the fact that, (one day) you'll have a very complicated network of entangled particles, all performing complex operations...Entire digital textbooks describing this new field of science (and therefore an entirely NEW field of applied mathematics), will be spawned from this very important research....The implications are far reaching: from artificial intelligence, to photonics / communications systems which will more than likely rely on entangled particles at a distance spanning thousands of light-years across....[Nick]
