Birds and Quantum Entanglement

European robins can maintain quantum entanglement in their eyes a full 20 microseconds longer than the best laboratory systems, say physicists investigating how birds may use quantum effects to "see" Earth's magnetic field.The quantum compass mechanism hasn't been conclusively demonstrated, but multiple lines of research point towards its existence. Findings like this one underscore its apparently extraordinary sophistication."How can a living system have evolved to protect a quantum state as well - no, better - than we can do in the lab with these exotic molecules?" said quantum physicist Simon Benjamin of the University of Oxford and the National University of Singapore, a co-author of the new study. "That really is an amazing thing.
