First-order Monte Carlo wavefunction method 10 1. Computing single-time expectation values 11 on the level of a single atom, ion, molecule, photon or electron. As a result, the need to better understand dynamics in open quantum systems has increased. While philosophically it would be possible to extend in Cavity QED [57, 58]. The solid curve is a result of Monte-Carlo simulation of the phase diffusion induced by atom detections, in good correspondence with the measured data. The simulation takes into account cavity relaxation, the finite cavity temperature and the limited efficiency of atom detection.
We start with a two-level atom with mass μ and transition frequency ω a strongly coupled to a single-mode cavity field with frequency ω upper and lower states of the atom are represented as | e 〉 and | g 〉, coupling strength between the atom and the cavity field is g.A plane standing-wave laser with frequency ω p and pumping strength η t, which is perpendicular. ics [12, 13]. Some new phenomena, such as cavity cool-ing [14, 15], atomic self-organization [16–19], and Dicke model phase transition [20–22] alsoappear in cavity QED systems. When an atom is pumped by a far-detuned standing-wave laser perpendicular to the cavity axis,two ordered spatial modes are quickly formed, with the peaks of the.

Key words and phrases: Quantum annealing, quantum computing, Markov chain Monte Carlo, Ising model, ground state success probability, Hamilto-nian, quantum bit (qubit). Yazhen Wang is Chair and Professor, Department of. Atoms interact with each other through the electromagnetic field, creating collective states that can radiate faster or slower than a single atom, i.e., super- and sub-radiance. When the field is.

By integrating the techniques of laser cooling and trapping with those of cavity quantum electrodynamics (QED), single Cesium atoms have been trapped within the. Under external illumination by a near-resonant laser, up to 90% of the atom's fluorescence is emitted into the resonant cavity mode.
The sub-Poissonian statistics of the cavity output and the Purcell enhancement of the atomic decay rate are confirmed by the observation of a strongly narrowed antibunching dip in the photon autocorrelation function.
A single atom coupled to a single mode of the radiation eld became a model system for the fundamental study of QED. This system has been experimentally realized in the domain of cavity QED, which exploits the modi ed mode density in con ned space, for example between two highly re ecting mirrors, to resonantly enhance the.

We are interested in the quantum statistical properties of the cavity eld at steady state. Currently far off resonance optical dipole trap has been used to control the neutral atoms.
Through the low loss micro resonator, the strong interaction between light field and atom can be implemented, thus the cavity QED system can be used as a sensitive single atom and single photon detector to do the measurement on single quanta level.

spin-1=2) strongly interacting with a mesoscopic quantum oscillator (a spring). In the cavity QED case, the oscillator is a single mode of a high quality cavity, interacting with a single atom. In the ion trap experiments, the oscillator is the mechanical motion of the ion in the trap, coupled by appropriatelaserbeams to the ion’s internalstate.
We consider a single atom laser (microlaser) operating on three-level atoms interacting with a two-mode cavity. The quantum statistical properties of the cavity eld at steady state are investigated by the quantum trajectory method which is a Monte Carlo simulation applied to open quantum systems.

After a short introduction of relevant theoretical aspects of the atom-cavity system we show the experimental results and compare the data with.
Feedback is one of the most powerful techniques for the control of classical systems. An extension into the quantum domain is desirable as it could allow the production of non-trivial quantum. We use the quantum theory of cascaded open systems to calculate the transmitted photon flux for a weak beam of photons from a cavity QED laser strongly focused onto a single, resonant two-state atom in the narrow-bandwidth limit.
We study the dependence of the transmitted flux on the quantum. The quantum trajectory method is a Monte Carlo Method applied to a quantum system. A single trajectory of the Microlaser is the one corresponding to a certain evolution of the atom-field state as the atoms pass through the Microlaser cavity subjected to a series of quantum jumps corresponding to all possible events that can occur during and.
The creation of a photon–atom bound state was first envisaged for the case of an atom in a long-lived excited state inside a high-quality microwave cavity 1, practice, however, light forces.Nonlinear spectroscopy of a single-atom-cavity system [Elektronische Ressource] / Ingrid Schuster: Technische Universitat MunchenMax-Planck-Institut fur QuantenoptikNonlinear spectroscopy of asingle-atom-cavity systemIngrid SchusterVollstandiger Abdruck der von der Fakultat fur Physikder Technischen Universitat Munchenzur Erlangung des akademischen Grades einesDoktors der Naturwissenschaften.Scientific Publications.
