Entangling Two Photons Serving Two Distinct Purposes
Entangling Two Photons Serving Two Distinct Purposes. Diligent efforts at the U.S. National Institute of Standards and Technology have produced entangled photons of two different wavelengths. The image below and the following explanation sum up this creative device. By carefully engineering the geometry of a micrometer-scale, ring-shaped resonator, researchers at NIST produced pairs of entangled photons […]
