Quantum Network Joins Four People Together For Encrypted Messaging (newscientist.com)
An anonymous reader shares a report: The quantum internet is starting small, but growing. Researchers have created a network that lets four users communicate simultaneously through channels secured by the laws of quantum physics, and they say it could easily be scaled up. Soren Wengerowsky at the University of Vienna and his colleagues devised a network that uses quantum key distribution (QKD) to keep messages secure [the link is paywalled]. The general principle of QKD is that two photons are entangled, meaning their quantum properties are linked. Further reading: Nature.

Hello, I am Quantor Prince and have been stranded in entanglement after secret experiment from my captors. I have made causality agreement with guard who is willing to free and not free me for the sum ..
ARPAnet also started with just four nodes: https://www.scientificamerican...
Sure they would. You'd just put it on your ridiculously insecure phone or Intel ME chip anyway.
Government : "You sure showed us, lol."
Hello, I have found SchrÃdinger's cat. Is he dead or is he alive? $50,000 to bet.
Did you run out of bitcoin stories?
Nobodys buying that crap anymore, dummy
You remember what happened, when Alexander Graham Bell added a third phone to his 'network'.
He was relaxing in his bath when the phone rang. Wet like a dog he hobbled to the phone just do detect the first ever 'wrong number'.
It said I had a message. I opened it and it wasn't there!?
I knew this because my quantum ai blockchain device from Elon Musk had already told me.

At the end of the day this is all still rooted in symmetric encryption. Given todays cost and capability of storage it's just as easy to pre-fill a lifetime supply of "messaging" or voice communications in an OTP pool as it would be to initially provision secret keys in quantum modem doodads to support quantum encryption.
Only OTP pools are way cheaper and easier.
Where quantum crypto would be useful is in securing high bandwidth (multi-gigabit) data links.
Or perhaps they will, and our own paranoia will keep us in our place.
Why bother putting the resources in spying on us when it is much easier to make us think that we are being spied on.
If something is so important that you feel the need to post it on the internet... It probably isn't that important.
Article is behind a paywalled and I can't find a non-paywalled source, thanks so much for that.
Wasn't there a movie about this? But I thought it was only three people.
No one has ever been able to detail how entangling particles helps anything with regards to encryption or key sharing.
If you pass out entangled particles to a set of people, all you gain is the ability to know the state of their particle as soon as you look at yours. (And you could have done that at the time you distributed the particles - there's no FTL transfer of information, and no breaking of causality.)
If you are able to securely pass out entangled particles, you are able to securely pass out convention particles describing a conventional key.
If you are not able to securely pass out entangled particles, you're not gonna do much, are you?

That headline summary sounds like a bad SyFy reboot of The Fly.
With Stan Winston gone I'm not sure it could be done properly.

Lawyers created secure networks that decades ago. If you don't pay ("the link is paywalled") you can't see the message. Or if you DO see, you have to poke your eyes out. (You've seen those email trailers from some companies: intended for; if not then you are restricted from [breathing] ...)
Besides, TERRORISTS, and "Here's a $5 wrench, go find out what he knows."
If the universe is someone's simulation -- does that mean the stars are just stuck pixels?
Next time you post a link to an article that's paywalled with no alternative source, we'll have a poll to see which body part of yours we get to remove.
The only way four people can keep a quantum secret is if three of them are dead, or a quantum superposition of alive and dead.
The death certificates will say "Cause of death: wavefunction collapse."
Corruption is convincing someone that the selfless ideal is the same as their selfish ideal.
What's the porn like on that network?
I've abandoned my search for truth; now I'm just looking for some useful delusions.
If they stopped their entanglement bullshit and looked at it properly, you'd see it's proof of resonance in matter. All of that crystal at any given time must be in a single state, i.e. resonant, so at any given time the photons ejects must be the same. So if you filter for time (which they always do), the photons will be the same.
And lots of matter particles are resonant, so can lots of light 'photons' resonant and behaving like a single photon. in other words the photon isn't a single big particle, its lots of smaller resonant things. So they don't need to talk this bullshit to fix up their model, the fix is in the logic of their own experiment!... The light goes through BOTH slits, not just a 'probabilistic wave function'.
It's not suitable for encryption, every nF spins later the state will be the same (depends on the structure).
Entanglement as 'understood' currently:
https://www.youtube.com/watch?v=8ORLN_KwAgs
Entanglement as reality:
1. All entanglement experiments filter for 'successful entanglement', in Quantum Eraser this is a 'Coincidence circuit', selecting photons that arrive at the same time. In the Delft's recent experiment it was an explicit filtering before the Bells threshold test.
2. Selecting photons ejected by the beta barium borate (BBO) crystal at time T=0, selects a subset of photons with a particular polarization.
3. All the matter in the BBO crystal must be in the same oscillating mode at T=0, that causes all photons to be ejected with a corresponding polarization.
4. T =0 is arbitrary, the experiment does not force a time, so all of the matter across the crystal must in the same state at any given time.
4. i.e. matter is resonant.
5. Since the only known force in light is electric (and its magnetic relative), that resonance must be electric.
6. Entanglement is proof of electric resonance in mass.
Entanglement Mk II:
You can extend the experiment to prove more:
1. Every 1F spin, the matter should be in the same state.
2. So if you can make an experiment that compares photons at T=0, against protons at T=1 spin, they will also be 'entangled'.
3. You would probably find it easier to work with W, the wavelength, which should be approximately the size of a current model of the proton (p*r*oton). The photon at X=0, should be 'entangled' with the one at X=W and X=2W, and X=3W...
Light rides electric resonance wave
1. Matter is resonating the electric resonance wave by the previous Entanglement experiment.
2. Light has an electric wave property.
3. So light is also riding the electric resonance wave., since it has an electric oscillating field it cannot do otherwise.
Experiments:
Obviously to be resonant, we need the electric force to propagate at infinity (even if the effects propagate through matter spins at the speed of light). So that would be the real winner here: Can you devise an experiment that can detect the initial push of electric force propagates at infinity velocity?
If the speed of matter and speed of light result from the dipolar oscillation over the resonance wave (with 0 and C being the lowest energy velocities, and C/2 being the maximum energy in velocity). Then *monopoles* are not limited to travel at C. (They wiggle, but this is the field from their wrapper). A discharged electron is a -ve monopole without its wrapper. Can you devise an experiment that measures the speed of these monopoles through a vacuum? Can you prove monopoles travel faster than light?
ostulate A: Mass isn't real
Postulate B: the energy in light is also 'kinetic'
Postulate C: Light bind force must be cyclical
Postulate D: only 2 fundamental particles are possible
Postulate E: the only force is electric
Postulate E2: The binding force (Postulate C) is electric
POSTULATE F: The speed of light is obvious
POSTULATE G: Time is measured in spins
POSTULATE H: All dipoles are equal, matter,even red and blue light
Postulate I1: Donut Particles
Postulate I2: Donut Particles are themselves
I haven't posted V1 yet, but these properties you claim are independent are not independent.
Spin I use as a proxy for time.
Location, your magic uncertain jiggle, I can explain and even make a prediction about, giving testable experiments, and its the basis for my gravity.
Polarization in V1 isn't a separate spin axis, it comes from velocity.
So you're taking a bunch of connected things, from a resonant system, and pretending they're independent parameters, that only become connected when you measure them.
It's total bullshit, once you see how it works, the penny drops and you cannot unsee it.
Look, the whole problem here with physics is its blind to the resonant field.
You have an oscillating electric field. You cannot measure it because any device you put in the field orders itself to be resonant with it.
A dipole is up-down, when the field under it is down-up. The matter of your equipment cancels the field it is trying to measure.
So you have Quantum mechanics models, and these model the inner monopole (+ve or -ve) as if a proton is jiggling around tracing out a sphere, or an electron is tracing out a disc, or some other structure. And you cannot see the donut/anti-donut wrappers around it that is causing that jiggle!
You're blind to large parts of matter, and blind to the underlying field.
So you have all these magic 'jiggles' which you wrap in a phrase "Heisenbergs uncertainty principle" as a way of not examining them.
These encryption 'jiggles' are not random, they are not suitable for encryption. They are obfuscation not encryption.
Or perhaps they will, and our own paranoia will keep us in our place.
Why bother putting the resources in spying on us when it is much easier to make us think that we are being spied on.
Just like people think the US millitary has tech that is 50 years ahead of anything in the consumer market?
