The researchers at the University of Innsbruck and the Université Paris-Saclay have developed a method for linking multiple quantum systems by trapping atoms in optical cavities. And then transferring the quantum information to light particles which can then be sent through optical fibers. They have successfully entangled two trapped ions located more than a few meters apart for the first time.
