What is quantum key distribution (QKD)?

Law of wave interference from two coherent sources. Depending on the phase difference two waves are added constructively or destructively. Sep 10, 2021 ... Laser (Light Amplification by Stimulated Emission of Radiation) is an artificial source of light radiation that emits a coherent beam of photons ... Jul 28, 2019 ... The answer is yes. This very short video demonstrates the point https://youtu.be/4o48J4streE. The mathematics behind this is the Van Cittert-Zernike theorem. The intensity ratio of two sources is 1: 4. For this interference pattern if the value of I max + I min I max − I min is equal to 2 α + 1 β + 3 then α β will be Mar 22, 2022 ...
