Accurately probing the delicate relationship between linked, or 'entangled', photons—irrespective of the distance between them—is an important element of quantum cryptography, and perhaps even teleportation. Now, A*STAR researchers have demonstrated an optimized way to detect entangled photons that involves using a 'witness family.'
