Phys. Rev. A 56, 1205–1211 (1997)Determination of entangled quantum states of a trapped atomReceived 18 September 1996; revised 17 March 1997; published in the issue dated August 1997 We propose a method for measuring entangled vibronic quantum states of a trapped atom. It is based on the nonlinear dynamics of the system that appears by resonantly driving a weak electronic transition. The proposed technique allows the direct sampling of a Wigner-function matrix, displaying all knowable information on the quantum correlations of the motional and electronic degrees of freedom of the atom. It opens possibilities for testing fundamental predictions of the quantum theory concerning interaction phenomena. © 1997 The American Physical Society URL:
