Entanglement between macroscopic objects generated by dissipation

(PhysOrg.com) — When generating entanglement between two objects, physicists typically try to minimize the objects’ interactions with the environment, since this interaction causes decoherence. But contrary to this thinking, scientists in a new study have experimentally demonstrated that dissipation caused by interaction with the environment can continuously generate entanglement between two macroscopic objects (two ensembles of cesium atoms containing about 1 trillion atoms all together).
