The quantum robin flits to a bare branch, restless. Twin sparks in his eyes whisper go south with every beat of his thimble heart.
Researchers have made crucial steps towards discovering how birds navigate. A newly discovered protein called Cry4 may help them to “see” Earth’s magnetic fields, a sense called magnetoreception. Inspired by this discovery that birds use quantum coherence of a protein in their eyes to sense magnetic fields, Hal Y. Zhang crafts a fantastical journey into quantum space.
