Abstract (en)
[origin: WO0075730A1] A system of etching using quantum entangled particles to get shorter interference fringes. An interferometer (100) is used to obtain an interference fringe. N entangled photons are input to the interferometer (100). This reduces the distance between interference fringes by n, where again n is the number of entangled photons.
