Four single-photon states are generated and entangled on a single micrometre-scale silicon chip, and provide the basis for the demonstration of chip-to-chip quantum teleportation.

In a paper recently published in Nature magazine, researchers claim to have transferred data using the measurement of the states of quantum particles that are connected via quantum entanglement. Quantum entanglement is the physical phenomenon in which two entangled particles instantly reflect a...

Mind find this interesting Polymath, the 1st link, a Journal, requires institutional access, the 1st link was referenced in the 2nd link which is more descriptive. So I might disagree with you on this one!
After all, we don't have to know what the "transmitting" entangled particle's quantum state was or is, all we have to know is that it has changed. To send information, instantly, theoretically.
Unfortunately, my institution doesn't have access (thanks to funding issues). From the abstract, though, it looks like they are trying to do quantum tunneling of entangled states. This is different than using entanglement to communicate since tunneling is known to not happen instantaneously.
In entanglement, the two entangled particles have correlated properties. But to reveal that correlation requires measuring *both* particles and comparing the results. At each 'end', things look random.
It is more similar to having coin that is flipped many times with the top result and bottom result sent to different locations. At both ends, the sequences of results looks completely random. But, if you bring the results together, you can see that they are opposite in all cases.
The problem is that we cannot control the flip without destroying the entanglement.
PS: If you can get access to that article, I would be happy to read it and do a better analysis.
In tunneling, the results move slower than light from one location to another, but in a way that is not allowed classically.
