One molecule, one photon: Entanglement makes an imperceptible recoil measurable

For decades, light has been used to understand the molecular structures of matter. A sample is irradiated with light, and measurements determine the wavelengths at which it is absorbed. Since each molecule absorbs light at very specific wavelengths that depend on its structure, t This story matters for Science & Discovery readers tracking certification. Reported by phys.org.
