Twenty-five years after the invention of quantum teleportation, the concept of entanglement gained enormous popularity. This is especially nice to those who remember that entanglement was not even taught at universities until the 1990s. Today, entanglement is often presented as a resource, the resource of quantum information science and technology. However, entanglement is exploited twice in quantum teleportation. Firstly, entanglement is the “quantum teleportation channel”, i.e., entanglement between distant systems. Second, entanglement appears in the eigenvectors of the joint measurement that Alice, the sender, has to perform jointly on the quantum state to be teleported and her half of the “quantum teleportation channel”, i.e., entanglement enabling entirely new kinds of quantum measurements. I emphasize how poorly this second kind of entanglement is understood. In particular, I use quantum networks in which each party connected to several nodes performs a joint measurement to illustrate that the quantumness of such joint measurements remains elusive, escaping today’s available tools to detect and quantify it.

Near Future

The knowledge and technologies invented and accumulated in the field of quantum information science are turning into near-future industrial technologies and products. The most obvious example is the quantum computer, in which many IT giants started investing large sums to develop. Besides the quantum computer, 'quantum technologies' also includes sensing and communication. Dr Yuimaru Kubo is an expert on quantum information science and technologies with 'spins in gem crystals'. He is based at the Okinawa Institute of Science and Technology (OIST) where his research team is currently investigating how quantum information can be stored, transmitted, or amplified with unprecedented efficiencies utilising the spins of electrons or nuclei in 'gem crystals'.
