Birds See Earth's Magnetic Field With Quantum Physics | 2021

追加: 2026-05-22

[00:00:00]In 2021, scientists [music] proved birds see Earth's magnetic field using quantum entanglement. The molecule that does it lives inside the bird's eye. European robins carry a protein called cryptochrome 4 in their retinas. Light triggers an entangled radical pair.

[00:00:18]Shu and colleagues at Oldenburg published the proof in nature in 2021.

[00:00:23]The entanglement lasted long enough to sense the field. Quantum effects work in warm, wet biology, not just supercooled labs. Your senses are not the only kind possible.
