Quantum Stochastic Heating of a Trapped Ion
نویسندگان
چکیده
The resonant heating of a harmonically trapped ion by a standing-wave light field is described as a quantum stochastic process combining a coherent Schrödinger evolution with Bohr-Einstein quantum jumps. Quantum and semi-quantum treatments are compared. ©c 2007 Optical Society of America OCIS codes: (270.2500) Fluctuations, relaxations, and noise; (270.1670) Coherent optical effects.

Dynamical evolution of nonclassical properties in cavity quantum electrodynamics with a single trapped ion
In this paper, by considering a system consisting of a single two-level trapped ion interacting with a single-mode quantized radiation field inside a lossless cavity, the temporal evolution of the ionic and the cavity-field quantum statistical properties including photon-counting statistics, quantum fluctuations of the field quadratures and quantum fluctuations of the ionic dipole variables are...
متن کامل0 Quantum and classical chaos for a single trapped ion
In this paper we investigate the quantum and classical dynamics of a single trapped ion subject to non-linear kicks derived from a periodic sequence of Gaussian laser pulses. We show that the classical system exhibits diffusive growth in the energy, or 'heating', while quantum mechanics suppresses this heating. This system may be realised in current single trapped-ion experiments with the addit...

متن کاملScaling and suppression of anomalous heating in ion traps.
We measure and characterize anomalous motional heating of an atomic ion confined in the lowest quantum levels of a novel rf ion trap that features moveable electrodes. The scaling of heating with electrode proximity is measured, and when the electrodes are cooled from 300 to 150 K, the heating rate is suppressed by an order of magnitude. This provides direct evidence that anomalous motional hea...
متن کاملStochastic control of quantum dynamics for a single trapped system
A stochastic control of the vibrational motion for a single trapped ion/atom is proposed. It is based on the possibility to continously monitor the motion through a light field meter. The output from the measurement process should be then used to modify the system’s dynamics.
