We analyze and further develop our method of quantum-state holography for reconstructing quantum superposition states in molecules or atoms [Phys. Rev. Lett. 80, 1418 (1998)]. The technique is based on mixing the unknown object state with a known ref

We apply the method of “coherence observation by interference noise” (COIN) to molecular wave packet interferometry. In contrast to conventional wave packet interferometry, where one has to control precisely the relative phase between the pair of

We introduce a method for reconstructing quantum superposition states excited in molecules or atoms by short laser pulses. The technique is based on mixing the unknown object state with a known reference state generated in the same system by an addit

We show that three real-valued parameters govern the quantum motion of an ion stored in the Paul trap. These parameters are two angles of rotation in phase space and a squeezing parameter. The time dependence of these parameters simplifies considerab

Many transient signals from quantum systems result from beats among a large number of levels whose energies depend nonlinearly on the quantum number. Typical examples range from time-resolved laser femtochemistry to quantum optics of single atoms in

We reconstruct the density operator of the center-of-mass motion of an ion stored in a Paul trap by mapping the dynamics of the motion onto the internal dynamics of the ion. Our technique takes into account the explicit time dependence of the trap po

Summary form only given. The problem of how to measure the wavefunction of a quantum system in amplitude and phase has attracted a lot of attention over the last few years. In this paper we analyze and further develop our method of quantum state holo
