Query: Generation of NOON states in waveguide arrays   We present a method to generate NOON states with three photons by injecting
photons in an array of three waveguides. Conditional measurements project the
wave function in a given (desired) state. In passing, we show how the array of
three waveguides, that effectively reproduces the interaction of three fields,
may be reduced to the interaction of two fields.
