Abstract

We demonstrate a new simultaneous normalized detection technique for fluorescence detection of ultracold atoms in a superposition of ground-state hyperfine levels. Using this technique we observe atom shot-noise limited detection signal-to-noise ratios in excess of 7800:1 per shot and 14400:1 in 1 s.

Low Noise Simultaneous Fluorescence Detection of Two Atomic States (PREPRINT)

M. Cashen, Fixler, J. B., Grant W. Biedermann +1 more

We have demonstrated a new technique for fluorescence detection of ultracold atoms. Fluorescence from two spatially separated clouds of ultracold atoms illuminated by a mutual probe laser was imaged onto opposite quadrants of a position-sensitive detector. The populations in the two separated atomic clouds were measured by integrating the quadrant detector photocurrents. Simultaneous detection of the populations of the two atomic clouds was used to reduce noise caused by fluctuations in detection laser amplitude and frequency. Using this technique we observed quantum projection noise limited detection signal-to-noise ratios exceeding 2000:1. To demonstrate the application of our highly Sensitive detection we compared two atomic clocks with interrogation times of only 80 ms to obtain a relative frequency stability of 1x 10(exp -13) Tau (exp -1/2) where TAU is the integration time in seconds.

Low-noise detection of ultracold atoms

J. M. McGuirk, G. T. Foster, J. B. Fixler +1 more

We have demonstrated a new technique for detecting ultracold atoms. A balanced detection technique was used to reduce laser-induced detection noise in conjunction with modulation-transfer spectroscopy to distinguish cold atoms from a thermal cloud. Using this technique, we have achieved signal-to-noise ratios in excess of 2000:1.

Fluorescence detection at the atom shot noise limit for atom interferometry

E Rocco, R N Palmer, T. Valenzuela +3 more

Atom interferometers (AIs) are promising tools for precision measurement with applications ranging from geophysical exploration and tests of the equivalence principle of general relativity to the detection of gravitational waves. Their optimal sensitivity is ultimately limited by their detection noise. We review resonant and near-resonant methods to detect the atom number of the interferometer outputs, and we theoretically analyze the relative influence of various scheme dependent noise sources and the technical challenges affecting the detection. We show that for the typical conditions under which an AI operates, simultaneous fluorescence detection with a charge-coupled device sensor is the optimal imaging scheme. We extract the laser beam parameters such as detuning, intensity, and duration required for reaching the atom shot noise limit.

Sub-atom shot noise Faraday imaging of ultracold atom clouds

M A Kristensen, Miroslav Gajdacz, P L Pedersen +4 more

Abstract We demonstrate that a dispersive imaging technique based on the Faraday effect can measure the atom number in a large, ultracold atom cloud with a precision below the atom shot noise level. The minimally destructive character of the technique allows us to take multiple images of the same cloud, which enables sub-atom shot noise measurement precision of the atom number and allows for an in situ determination of the measurement precision. We have developed a noise model that quantitatively describes the noise contributions due to photon shot noise in the detected light and the noise associated with single atom loss. This model contains no free parameters and is calculated through an analysis of the fluctuations in the acquired images. For clouds containing N ∼ 5 × 10 6 atoms, we achieve a precision more than a factor of two below the atom shot noise level.

Preparation of mesoscopic atomic ensembles with single-particle resolution

Andreas Hüper, Cebrail Pür, Hetzel, M. +7 more

The analysis of entangled atomic ensembles and their application for interferometry beyond the standard quantum limit requires an accurate determination of the number of atoms. We present an accurate fluorescence detection technique for atoms that is fully integrated into an experimental apparatus for the production of many-particle entangled quantum states. Single-particle resolving fluorescence measurements for $1$ up to $30$ atoms are presented. According to our noise analysis, we extrapolate that the single-atom resolution extends to a limiting atom number of $390(20)$ atoms. We utilize the accurate atom number detection for a number stabilization of the laser-cooled atomic ensemble. For a target ensemble size of $7$ atoms prepared on demand, we achieve a $92(2)\,\%$ preparation fidelity and reach number fluctuations $18(1)\,\mathrm{dB}$ below the shot noise level using real-time feedback on the magneto-optical trap.

Limit to Minimally Destructive Optical Detection of Atoms

J. J. Hope, J. D. Close

All optical techniques used to probe the properties of Bose-Einstein condensates have been based on dispersion and absorption that can be described by a two-level atom. Both phenomena lead to spontaneous emission that is destructive at the low energies involved with ultracold atomic systems. Recently, both were shown to lead to the same limit to the signal to noise ratio for a given destruction. We develop a new method for calculating the phase shift of a laser beam and show that no single-pass optical technique using classical light and a three-level atom can exceed this limit. This puts significant restrictions on potential nondestructive measurement schemes.
