(Phys.org)—A team of German physicists has successfully demonstrated an ability to perform quantum key distribution (QKD) exchange between an airplane in flight and a ground station, paving the way perhaps to the same kinds ...
In conventional holography, the hologram is formed by recording the interference fringes of two coherent beams using a photosensitive material. The amplitude and phase information of the original signal wave can be reconstructed ...
