Abstract

Of particular interest in quantum optics is the study of atom-cavity interactions in the strong coupling regime in which an intracavity photon is likely to be absorbed and reemitted before escaping into the external environment. We have recently achieved conditions appropriate to this regime in an apparatus consisting of a beam of Cesium atoms coupled to an optical resonator of finesse 330,000 and length 0.35 mm.

Trapping of Single Atoms in Cavity QED

J. Ye, David W. Vernooy, Harry J. Kimble

By integrating the techniques of laser cooling and trapping with those of cavity quantum electrodynamics (QED), single cesium atoms have been trapped within the mode of a small, high finesse optical cavity in a regime of strong coupling. The observed lifetime for individual atoms trapped within the cavity mode is $\ensuremath{\tau}\ensuremath{\approx}28\mathrm{ms}$, and is limited by fluctuations of light forces arising from the far-detuned intracavity field. This initial realization of trapped atoms in cavity QED should enable diverse protocols in quantum information science.

Optical Physics with Finesse - Dissipative Quantum Dynamics for Atoms in a Cavity with R=0.9999984

Harry J. Kimble, Gerhard Rempe, Robert J. Thompson

While for the most part quantum statistical processes in quantum optics are investigated in a weak coupling regime, it has recently become possible to realize experimentally optical systems for which the internal coupling coefficient g is comparable to the external dissipative rates. Within this context the subject of our investigation is the quantum dynamical processes for a collection of N two-state atoms strongly coupled to a single mode of a high finesse optical cavity, Our particular experiment consists of a small collection of Cesium atoms (6S1/2, F = 4 → 6P3/2, F = 5 transition at 852nm) interacting with the TEM00 mode of a spherical mirror cavity. The critical technical advance for this work is the attainment of extremely low loss mirrors for high finesse (103 – 106) and hence long photon lifetime even in a small cavity.[1]

For the most part, quantum statistical processes in quantum optics are investigated in a weak-coupling regime, but it has become possible recently to realize experimentally optical systems for which the internal coupling coefficient g is comparable to the external dissipative rates. Within, this context, the subject of our investigation is the quantum dynamical processes for a small collection of N two-state atoms strongly coupled to a single mode of a high-finesse optical cavity. For this system, we record input-output characteristics for steady-state operation with 3 ⪝ N ⪝ 65 intracavity atoms and observe optical bistability for N⪞15 atoms.1

Finite detection window in photon coincidence spectroscopy

Barry C. Sanders, Levente Horvath, B. F. Wielinga

Summary form only given.The Jaynes-Cummings model (JCM) of a two-level atom interacting with a single mode of a high-finesse cavity in the strong-coupling regime forms the basis of studies in strong-coupling cavity quantum electrodynamics. Jaynes and Cummings demonstrated that the semiclassical model of radiation could account for the observed properties of the coupled atom-cavity system, and it has remained a challenge to observe the nonclassical features of the JCM, specifically those that reveal quantum entanglement between the atomic internal degrees of freedom and the single-mode cavity field. The key to observing nonclassical effects is to access the nonlinear regimen of the spectrum (beyond the first couplet of the JCM ladder). This has been accomplished in the microwave domain, but the optical domain presents difficulties that are not significant in the microwave experiments. Recently, the method of photon coincidence (or correlation) spectroscopy (PCS) has been proposed to overcome these difficulties and provide an experimental signature of the nonlinear regimen of the JCM spectrum. The atom is excited directly by a bichromatic laser field, and two-photon coincidence detection is performed on the cavity output field. Here we consider the complication that arises because the two-photon de-excitation is not instantaneous: the temporal separation between the two photons in the pair is random and of the order of the cavity lifetime. We also determine the optimal window time T for detecting photon pairs in order to maximize the number of genuine pairs while minimizing the number of false pairs. Our simulations, using a Bloch function expansion for solving the master equation, yield optimal values of T.

Spectroscopy of strongly coupled atom-cavity systems: A topical review

G. S. Agarwal

A new nonperturbative regime of radiation-matter interaction is examined by considering atoms interacting with fields in exceptionally high quality cavities. A general framework for the study of such systems is presented. The new features that arise from the strong coupling to the cavity mode are thoroughly analysed and the underlying physics and experiments are reviewed. The nonlinear processes are shown to be very sensitive to the sample size.

Correlating Photons Using the Collective Nonlinear Response of Atoms Weakly Coupled to an Optical Mode

Jürgen Volz, Adarsh S. Prasad, Jakob Hinney +7 more

The generation of correlated photons typically requires a highly nonlinear medium that is strongly coupled to an optical mode. Recently, significant advances have been made in this direction by strongly coupling photons to quantum emitters and exploiting the inherently nonlinear response of the latter. A number of methods have been pursued for this purpose, employing, e.g., high finesse optical cavities or strongly interacting Rydberg atoms. However, the implementation of strong and low-loss photon-photon interactions remains a challenging goal.
