In an experiment, performed recently in the laboratory of Professor Mika Sillanpää at Aalto University in Finland, we set up two microfabricated vibrating circular membranes, like drumheads. Each was about the width of a human hair and we were able to measure them in a state that exhibited the quantum property of entanglement.
The two drumheads were brought into an entangled state through careful driving of a superconducting electrical circuit to which both were coupled. While these drumheads may seem small on the human scale, they are huge on the atomic scale – each drumhead is composed of trillions of atoms.
These drumheads are the largest objects to be prepared in an entangled state, and this experiment is perhaps the closest approach to a literal implementation of the famous thought experiment of Einstein, Podolsky and Rosen that first studied the phenomenon that became known as entanglement back in 1935.
