Cavity QED "By The Numbers"

The number of atoms trapped within the mode of an optical cavity is determined in real time by monitoring the transmission of a weak probe beam. Continuous observation of atom number is accomplished in the strong coupling regime of cavity quantum electrodynamics and functions in concert with a cooling scheme for radial atomic motion. The probe transmission exhibits sudden steps from one plateau to the next in response to the time evolution of the intracavity atom number, from N >= 3 to N = 2 to 1 to 0, with some trapping events lasting over 1 second.The number of atoms trapped within the mode of an optical cavity is determined in real time by monitoring the transmission of a weak probe beam.

Quantum manipulation and measurement of single atoms in optical cavity QED

Jun Ye, Christina J. Hood, T. W. Lynn +3 more

Using laser-cooled atoms strongly coupled to a high finesse optical cavity, we have performed real-time continuous measurements of single atomic trajectories in terms of the interaction energy (E/sub int/) with the cavity. Individual transit events reveal a shot-noise limited measurement (fractional) sensitivity of 4/spl times/10/sup -4///spl radic/Hz to variations in E/sub int///spl planck/ within a bandwidth of 1300 kHz. The strong coupling of atom and cavity leads to a maximum interaction energy greater than the kinetic energy of an intracavity laser-cooled atom, even under weak cavity excitation. Evidence of mechanical light forces for intracavity photon number <1 has been observed. The quantum character of the nonlinear optical response of the atom-cavity system is manifested for the trajectory of a single atom.Using laser-cooled atoms strongly coupled to a high finesse optical cavity, we have performed real-time continuous measurements of single atomic trajectories in terms of the interaction energy (E/sub int/) with the cavity.

State-Insensitive Cooling and Trapping of Single Atoms in an Optical Cavity

J. McKeever, J. R. Buck, A. David. Boozer +4 more

Single cesium atoms are cooled and trapped inside a small optical cavity by way of a novel far-off-resonance dipole-force trap, with observed lifetimes of $2--3\text{ }\mathrm{s}$ . Trapped atoms are observed continuously via transmission of a strongly coupled probe beam, with individual events lasting $\ensuremath{\simeq}1\text{ }\text{ }\mathrm{s}$. The loss of successive atoms from the trap $N\ensuremath{\ge}3\ensuremath{\rightarrow}2\ensuremath{\rightarrow}1\ensuremath{\rightarrow}0$ is thereby monitored in real time. Trapping, cooling, and interactions with strong coupling are enabled by the trap potential, for which the center-of-mass motion is only weakly dependent on the atom's internal state.Single cesium atoms are cooled and trapped inside a small optical cavity by way of a novel far-off-resonance dipole-force trap, with observed lifetimes of $2--3\text{ }\mathrm{s}$.

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.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.

Cavity probe for real-time detection of atom dynamics in an optical lattice

Robert D. Niederriter, Chandler Schlupf, Paul Hamilton

We propose and demonstrate real-time subwavelength cavity QED measurements of the spatial distribution of atoms in an optical lattice. Atoms initially confined in one ``trap'' standing wave of an optical cavity mode are probed with a second ``probe'' standing wave. With frequencies offset by one free spectral range, the nodes of the trap fall on the antinodes of the probe in the $\ensuremath{\approx}{10}^{4}$ lattice sites around the center of the cavity. This lattice site independent atom-cavity coupling enables high sensitivity detection of atom dynamics even with atoms spread over many lattice sites. To demonstrate, we measure the temperature of $20--70\phantom{\rule{4pt}{0ex}}\ensuremath{\mu}\mathrm{K}$ atom ensembles in $<10\phantom{\rule{4pt}{0ex}}\ensuremath{\mu}\mathrm{s}$ by monitoring their expansion by $\ensuremath{\approx}100$ nm after sudden release from the trap lattice. Atom-cavity coupling imprints the atom dynamics on the probe transmission. The technique will enable improved nondestructive detection of Bloch oscillations and other atom dynamics in optical lattices.We propose and demonstrate real-time subwavelength cavity QED measurements of the spatial distribution of atoms in an optical lattice.
