Entanglement is a link between two sister particles or objects, making them behave as a single entity. Researchers at the Niels Bohr Institute, University of Copenhagen, entangled a mechanical oscillator—a vibrating dielectric membrane—with an atom cloud's spin (magnetic orientation). These very different entities were possible to entangle by connecting them with photons, particles of light. Atoms can be useful in processing quantum information, and the membrane—or mechanical quantum systems in general—can be useful for the storage of quantum information.
Professor Eugene Polzik, who led the effort, states that: "With this new technique, we are on route to pushing the boundaries of the possibilities of entanglement. The bigger the objects, the further apart they are, . . . the more interesting entanglement becomes from both fundamental and applied perspectives. With the new result, entanglement between very different objects has become possible."
The experiment might be a step towards limitless precision of measurements of motion.Read the whole article in Phys.org
