Quantum information teleported across a rudimentary quantum network:
The power of a future quantum Internet is based on the ability to send quantum information (quantum bits) between the nodes of the network. This will enable all kinds of applications such as securely sharing confidential information, linking several quantum computers together to increase their computing capability, and the use of highly precise, linked quantum sensors.
[...] In order to be able to teleport quantum bits, several ingredients are required: a quantum entangled link between the sender and receiver, a reliable method for reading out quantum processors, and the capacity to temporarily store quantum bits. Previous research at QuTech demonstrated that it is possible to teleport quantum bits between two adjacent nodes. The researchers at QuTech have now shown for the first time that they can meet the package of requirements and have demonstrated teleportation between non–adjacent nodes, in other words over a network. They teleported quantum bits from node "Charlie" to node "Alice", with the help of an intermediate node "Bob".

Were the quantum bits tagged to enable personalised advertising and intrusive tracking across the quantum internet?

Not yet. But the content industry made sure they come with built-in copy protection.

So does this create a possibility for creating a communication device, once quantumly established, is able to transcend time?
In other words, once you turn it on, will it be receiving messages from the future instead of the past?

No. As long as it adheres to the rules of quantum mechanics, you can't use it to send messages into the past, or faster than light.
