The decoherence of nonclassical motional states of a trapped $^9 {\rm Be^+}$ ion in a recent experiment is investigated theoretically. Sources of decoherence considered here destroy the characteristic coherent quantum dynamics of the system but do not cause energy dissipation. Here they are first introduced phenomenologically and then described using a microscopic Hamiltonian formulation. Theoretical predictions are compared to experimental results.

Decoherence in non-classical states of a trapped ion
We assume that the origin of decoherence of non-classical motional states of a trapped ion is due to the coupling of the vibronic modes with classical stochastic electric fields and to the finite
Decoherence of motional states of trapped ions
Abstract We have studied the decoherence of motional-state superpositions of single trapped ions caused by their coupling to fluctuating fields. We illustrate these studies by showing how
Decoherence of motional superpositions of a trapped ion
Abstract We summarize experiments on the decoherence of motional superposition states of single trapped ions which were carried out at NIST. The decoherence was characterized by the loss of contrast
Non-dissipative decoherence in Rabi oscillation experiments
Abstract Decoherence may be due to the fluctuations of some classical variable or parameter of a system, and not only to the entanglement with the environment. Here we derive a model-independent
Decoherence of trapped-atom motional state superpositions
Experiments that investigate the decoherence of superpositions of motional states of trapped ions are described. Decoherence is characterized by the loss of contrast in Ramsey-type interferometer
Nonextensive approach to decoherence in quantum mechanics
Abstract We propose a nonextensive generalization ( q -parametrized) of the von Neumann equation for the density operator. Our model naturally leads to the phenomenon of decoherence, and unitary
Decoherence induced by a phase-damping reservoir
A phase damping reservoir composed by N-bosons coupled to a system of interest through a cross-Kerr interaction is proposed and its effects on quantum superpositions are investigated. By means of
Non-Markovian dynamics of an open quantum system with nonstationary coupling.
The spectral, dissipative, and statistical properties of the damped quantum oscillator are studied in the case of non-Markovian and nonstationary system-heat bath coupling. The dissipation of
Decoherence of quantum superpositions through coupling to engineered reservoirs
Decoherence is induced by coupling the atom to engineered reservoirs, in which the coupling and state of the environment are controllable, and the decoherence rate scales with the square of a quantity describing the amplitude of the superposition state.
Decoherence of trapped-ion internal and vibrational modes: The effect of fluctuating magnetic fields
The effect of ambient magnetic fields on the dynamics of a single trapped ion is studied analytically. We consider two electronic states with energy separation stochastically varied by magnetic-field
