From the article:
A quantum internet could play a key role in tying together many of the most promising applications for quantum technologies. The main impetus for quantum communication networks today is security, because a feature of messages encoded in quantum states is that reading them changes their content, alerting the receiver to any eavesdropping.

From the article:
Scientists have now used drones to transmit particles of light, or photons, that share the quantum linkage called entanglement. The photons were sent to two locations a kilometer apart, researchers from Nanjing University in China report in a study to appear in Physical Review Letters.

From the article:
A team of physicists led by Professor Patrick Windpassinger at Johannes Gutenberg University Mainz (JGU) has successfully transported light stored in a quantum memory over a distance of 1.2 millimeters. They have demonstrated that the controlled transport process and its dynamics has only little impact on the properties of the stored light. The researchers used ultra-cold rubidium-87 atoms as a storage medium for the light as to achieve a high level of storage efficiency and a long lifetime.
