The Audacious Climate Control "Open Air Cloud Experiment": Geoengineers Ready First Device Testing Operations

After years of critics in the alternative media pointing to the lines in the lines in the sky left by planes laying so-called “chemtrails” or persistent aerosols, and tying it to efforts to alter the climate, the official narrative is catching up.
The Contra Costa Times reports:
A team of elder Silicon Valley scientists is building an audacious device that might solve one of humanity’s most profound dilemmas — a “cloud whitener” designed to cool a warming planet. […]
Their goal is to launch the nation’s first open-air field trial of controversial “geoengineering” at a still-unidentified site in Moss Landing. There, they would test the ability of an energy-efficient machine to hurl tiny seawater droplets into a graceful trajectory — the first step of a research project to boost the brightness of clouds to reflect rays of sunlight back into space. […]
“We are not interested in deploying it unless it’s necessary. But we’d like to have something available, so we know what works and what doesn’t work.”
Uh huh. So they just started for the first time ever? Right…
In truth, this cloud brightening experiment is being launched just months after several major meetings on geoengineering in the fall of 2014 and early months of 2015, which discussed moving geoengineering efforts “out of the lab and into the open.”
The Economist wrote in Dec 2014:
In the great wide open: Scientific studies of techniques for deliberately modifying the climate are getting ready to move out of the laboratory
The only problem is that the definition of “laboratory” is ill defined — scientists cannot test this technology inside research buildings and may have been unofficially testing them in open air “lab” we live in — just as GMO crop scientists have done.
In other words, this is all according to the script, not reality.
Closer to reality, the evidence for chemtrails, and the uninvited use of geoengineering to modify cloud cover, remains hotly debated and very controversial, but continually observed and reported all across the world.
We don’t have proper disclosure about what exactly has been going on, but we weren’t born yesterday either. Citizen journalists remain our best chance of pressuring those working on these secretive projects to admit what has been taking place, and what, if anything, the ramifications may be for human health and the environment.

Quantum Entaglement Light Photon Created to Contain Thousands of Atoms for Advanced Atomic Time Keeping

Physicists from MIT and the University of Belgrade have developed a new technique that can successfully entangle 3,000 atoms using only a single photon. The results, published today in the journal Nature, represent the largest number of particles that have ever been mutually entangled experimentally.

The researchers say the technique provides a realistic method to generate large ensembles of entangled atoms, which are key components for realizing more-precise atomic clocks.
“You can make the argument that a single photon cannot possibly change the state of 3,000 atoms, but this one photon does — it builds up correlations that you didn’t have before,” says Vladan Vuletic, the Lester Wolfe Professor in MIT’s Department of Physics, and the paper’s senior author. “We have basically opened up a new class of entangled states we can make, but there are many more new classes to be explored.”

Vuletic’s co-authors on the paper are Robert McConnell, Hao Zhang, and Jiazhong Hu of MIT, as well as Senka Cuk of the University of Belgrade.

Atomic entanglement and timekeeping

Entanglement is a curious phenomenon: As the theory goes, two or more particles may be correlated in such a way that any change to one will simultaneously change the other, no matter how far apart they may be. For instance, if one atom in an entangled pair were somehow made to spin clockwise, the other atom would instantly be known to spin counterclockwise, even though the two may be physically separated by thousands of miles.

The phenomenon of entanglement, which physicist Albert Einstein once famously dismissed as “spooky action at a distance,” is described not by the laws of classical physics, but by quantum mechanics, which explains the interactions of particles at the nanoscale. At such minuscule scales, particles such as atoms are known to behave differently from matter at the macroscale.
Scientists have been searching for ways to entangle not just pairs, but large numbers of atoms; such ensembles could be the basis for powerful quantum computers and more-precise atomic clocks. The latter is a motivation for Vuletic’s group.

Today’s best atomic clocks are based on the natural oscillations within a cloud of trapped atoms. As the atoms oscillate, they act as a pendulum, keeping steady time. A laser beam within the clock, directed through the cloud of atoms, can detect the atoms’ vibrations, which ultimately determine the length of a single second.

“Today’s clocks are really amazing,” Vuletic says. “They would be less than a minute off if they ran since the Big Bang — that’s the stability of the best clocks that exist today. We’re hoping to get even further.”

The accuracy of atomic clocks improves as more and more atoms oscillate in a cloud. Conventional atomic clocks’ precision is proportional to the square root of the number of atoms: For example, a clock with nine times more atoms would only be three times as accurate. If these same atoms were entangled, a clock’s precision could be directly proportional to the number of atoms — in this case, nine times as accurate. The larger the number of entangled particles, then, the better an atomic clock’s timekeeping.

Picking up quantum noise

Scientists have so far been able to entangle large groups of atoms, although most attempts have only generated entanglement between pairs in a group. Only one team has successfully entangled about 100 atoms — the largest mutual entanglement to date, and only a small fraction of the whole atomic ensemble.

Now Vuletic and his colleagues have successfully created a mutual entanglement among 3,000 atoms, virtually all the atoms in the ensemble, using very weak laser light — down to pulses containing a single photon. The weaker the light, the better, Vuletic says, as it is less likely to disrupt the cloud. “The system remains in a relatively clean quantum state,” he says.
