| 摘要: | We present a method for the direct measurement of the Wigner-function matrix for complex
vibronic states of a trapped atom, that is suited to analyse the entanglement between two motional degrees
of freedom and the internal electronic dynamics. It is a generalisation of the method for the determination
of vibronic quantum states [S. Wallentowitz, R.L. de Matos Filho, W. Vogel, Phys. Rev. A 56, 1205 (1997)]
in conjunction with the scheme for the direct observation of the Wigner function of a single motional degree
of freedom [L.G. Lutterbach, L. Davidovich, Phys. Rev. Lett. 78, 2547 (1997)]. The major advantage of
the present method is that it reduces the experimental e orts substantially. On the other hand, it is
demonstrated that the nonlinear vibronic coupling necessary for this method turns out to be its main
limitation. |
