    • It requires fast switchings of both the coherent excitation and the trap frequency, the latter by at least two orders of magnitude. Besides technical stability problems in such a method, in principle only a smoothed distribution can be reconstructed since the squeezing does not yield a perfect measurement of the generalized position as in our scheme. Note that both more significant and more stable squeezing could be achieved by the methods used in Ref. 20
    • An alternative approach to measure the quantum state beyond the Lamb-Dicke regime has been proposed by J.F. Poyatos, R. Walser, J.I. Cirac and P. Zoller, Phys. Rev. A 53, R1966 (1996). It requires fast switchings of both the coherent excitation and the trap frequency, the latter by at least two orders of magnitude. Besides technical stability problems in such a method, in principle only a smoothed distribution can be reconstructed since the squeezing does not yield a perfect measurement of the generalized position as in our scheme. Note that both more significant and more stable squeezing could be achieved by the methods used in Ref. 20.

    • This electronic preparation is a pure state, which can be described by coefficients (Formula presented)(0)=(Formula presented)(Formula presented). Nevertheless, also nonpure quantum states can be prepared to get the desired antisymmetrized spatial distribution. This only decreases the measurable fluorescence signal
