A team of American, European, and Asian researchers has produced macroscopic quantum-optical entanglement between two living mouse brain cells. The room-temperature experiment involved two single in-vitro cells separated by a distance of 40 cm, and used single near-IR photons produced by an attenuated stabilized narrow-linewidth laser as the mechanism to initiate the entanglement between the cells.
