Researchers from the Austrian Academy of Sciences and the University of Vienna have experimentally demonstrated what was previously only a theoretical possibility. Together with quantum physicists from the University of Science and Technology of China, they have succeeded in teleporting complex high-dimensional quantum states. The research teams report this international first in the journal Physical Review Letters.
In their study, the researchers teleported the quantum state of one photon (light particle) to another distant one. Previously, only two-level states ("qubits") had been transmitted, i.e., information with values "0" or "1". However, the scientists succeeded in teleporting a three-level state, a so-called "qutrit". In quantum physics, unlike in classical computer science, "0" and "1" are not an 'either/or' – both simultaneously, or anything in between, is also possible. The Austrian-Chinese team has now demonstrated this in practice with a third possibility "2".
Quantum teleportation moves one quantum state to another.
Usually done with two-dimensional pieces of information called qubits, scientists were able to transport 3-dimensional qutrits.
These qutrits could allow quantum computing to expand into the next generation.
PhysicsWorld: Quantum teleportation moves into the third dimension
this will be the area where creating sensing devices/AI robots and teleporting them to distant worlds within this Galaxy will be accomplished via Quantum-Entanglement and the property of 'spooky-action-at-Light-Years-distances'
So does this allow for communication of information?

Before you all jump to Hyperspace. Can anyone describe for a layman what they did?
The basic idea is that Alice and Bob share a pair of entangled particles (in the terminology of quantum cryptography, Alice being the sender of a message and Bob the receiver). Then Alice interacts a third particle – in an unknown state – with her half of the entangled pair, measures the outcome of the interaction, and then tells Bob the result via a classical channel. Given that information and a measurement on his half of the entangled pair, Bob is able to work out the original unknown state – which is what has been teleported.
