Tiny snippets of information can be stored as photons of light. The bits of data are encoded in the particle’s properties, like its polarization or phase. Reading the quantum information, however, can be tricky since photons tend to get distorted by environmental factors as they get transmitted.

Funded by the US Army Research Laboratory, a team of boffins [2]led by Louisiana State University (LSU), have figured out a way to correct these distortions in order to preserve data stored in the photons using machine learning. First, the properties of single photons are captured and processed as images.
Changes in temperature and atmospheric pressure, however, can disrupt the photons and change these images. So the team built a database of imperfect images that describe the light profiles of photons that have been impacted by these distortions. By training a neural network on the original, high quality images and its degraded versions, it can learn to restore botched images.

“These networks behave as an artificial brain that is trained with multiple distorted spatial profiles of photons produced by turbulence with different conditions, for example temperature,” Omar Magaña‐Loaiza, principal investigator of the experiment described in a paper [5]published in Advanced Quantum Technologies, and an assistant professor of physics at LSU, explained to The Register .
“The neural network translates the distorted photon profiles to numbers that can be understood by a computer. These networks rely on a series of operations that enable the implementation of image filters: these filters are like those used for image recognition.”
In short, machine learning algorithms can learn to correct these distorted images - or photon profiles - to accurately recover the quantum information stored within it.
“In classical protocols for communication, people send strings of zeros and ones, these possibilities are represented by two states, that lead to the concept of a bit of information. In the quantum context, these bits are quantum states known as quantum bits or qubits,” he added.
“In our case, we have a larger alphabet; instead of using only zeros and ones, each single photon can be prepared in more than two states. These states are known as qudits.
"In the communication protocol used in our experiment, we send strings of qudits. By doing this, we can send more than one bit of information in a single photon. If there is an error, we correct it using artificial neural networks.”
If quantum information containing an encrypted message was stored as a single photon, the neural network can make sure that they’re decoded more accurately. The US military is interested in quantum communications for a number of reasons. In theory, it’s more secure than sending data through code, which could be cracked.
“Distributed quantum information and quantum networking research are still in their early stages,” Dr Sara Gamble, program manager, Quantum Information Sciences, at the Army Research Office, told us.

“The work described in this paper is particularly exciting because it shows enormous promise for overcoming a common type of distortion that befalls quantum information during its distribution. There are, however, many hurdles still left to overcome before most real world applications can be realized.” ®

This is a "someone else's goose" story if I ever read one.
Beware the Grim Reaper ...... Doing GOD's Work .... for the Sake of Global Operating Devices
Wild Wacky Western defence forces certainly don't have far to go to find out that they are not alone labouring in such fields where it is most advantageous to be able to excel and exploit to exhaustion and collapse that which does not have the best interests of all at the heart of their operations. Anything else extraordinarily renders a perverse and corrupting unnatural leverage to just an unworthy few, who really should have known better than to believe they are especially chosen and an elite band of brothers and right mothers. And with their future fate fully dependent upon their every new action and thought shared in the full knowledge of that change of universal situation, one hopes that serial arrogant stupidity and continued ignorant hubris doesn't prevail whenever systems admins be instructed to mercilessly extract and exact a mercifully deadly personal toll.
And it is not as if such is not freely advised with info and intel clearly enough made readily available to them. Here be a recent missive directed specifically in their direction. Many here on El Reg should be well enough already aware of such ongoing developments/unfolding shenanigans, for they have definitely not been kept secret from them. Of that I am perfectly sure.

An ACTIve Astute Agile Partner in Competition or in Opposition to Uncle Sam's Plans in the Realms of Defence for Sectors of the Future, Mandy ? Surely everybody now realises that the tools of the past are no longer viable and effective in protecting and safely securing the future from great virtual harm physically impacting upon all SCADA command and remote control systems of the present to an overwhelming degree?
Such questions one does well to ask oneself of the following submission posted earlier elsewhere, but just as worthy and prescient to be shared here too, for it would appear to offer a great deal of what is being looked for, and is needed by the JAIC. .........

Like it or like it not, AI is a/the major future feature of everything today for tomorrow and of everything tomorrow from today. And there's diddly squat than can be done to either permanently prevent or temporarily halt the Inexorable Progress of Pioneering IntelAIgently Programmed Projects Demonstrating Powerful and Potential Leads/Available Derivative Future Options for Markets Appraisal, Valuation and Remote Relatively Anonymous and Practically Autonomous Realisation/AI Virtualisation ........ which perfectly succinctly explains the likes of a Pentagon Department interest.
Changed Times and Spaces indeed. :-) Heaven sent opportunities and devilish tasks abound everywhere and aint that the truth.

Electric is an oscillating force.
There, I've got the punchline down to one sentence. Electric is an oscillating force, all that implies you can realize for yourselves, just 5 words.
