We investigate in detail the effects of a QND vibrational number measurement made on single ions in a recently proposed measurement scheme for the vibrational state of a register of ions in a linear rf trap [C. D' Helon and G. J. Milburn , phys. Rev. A 54 , 5141 (1996)]. The performance of a measurement shows some interesting patterns which are closely related to searching.
