The only known methods for creating noon states with arbitrary $N$ via linear optics and projective measurments seem to have a limited range of application due to imperfect phase control. Here, we show that bootstrapping techniques can be used to create high-fidelity noon states of arbitrary size.3 pages, 1 figure, more formal derivation of Heisenberg limitQuantum Physicstext
