Classical synchronization indicates persistent entanglement in isolated quantum systems

As if by magic, seemingly independent pendulum clocks can come together to tick simultaneously and in synchrony. The phenomenon of "self-organized synchronization" frequently occurs in nature and engineering and is one of the key research fields of Marc Timme's team at the Max Planck Institute for Dynamics and Self-Organization. The physicists in Göttingen are part of a German-Italian collaboration which has now published an amazing discovery in Nature Communications: even quantum systems can s...
