Journal ArticleDOI
Quantum projection noise in an atomic fountain: a high stability cesium frequency standard
Giorgio Santarelli,Ph. Laurent,Pierre Lemonde,André Clairon,Anthony Mann,S. Chang,Andre N. Luiten,Christophe Salomon +7 more
TL;DR: In this article, an ultrastable cryogenic sapphire oscillator is used to measure the short-term frequency stability of the fountain as a function of the number of detected atoms.
Journal ArticleDOI
Considerations on the measurement of the stability of oscillators with frequency counters
TL;DR: The most common time-domain measure of frequency stability, the Allan variance, is typically estimated using a frequency counter as discussed by the authors, but the results typically reported by many laboratories using these counters are not, in fact, the Allen variance, but a distorted representation.
Journal ArticleDOI
Cold atom clocks and applications
Sébastien Bize,P. Laurent,Michel Abgrall,H. Marion,I. Maksimovic,Luigi Cacciapuoti,J. Grünert,C. Vian,F. Pereira Dos Santos,Peter Rosenbusch,Pierre Lemonde,Giorgio Santarelli,Patrick D. Wolf,André Clairon,Andre N. Luiten,Michael E. Tobar,Christophe Salomon +16 more
TL;DR: In this paper, the authors describe advances in microwave frequency standards using laser-cooled atoms at BNM-SYRTE, which lead to a frequency stability of 2 × 10−16 at 50'000 s for primary standards.
Journal ArticleDOI
Fast machine-learning online optimization of ultra-cold-atom experiments.
P. B. Wigley,P. J. Everitt,A. van den Hengel,John Bastian,M. A. Sooriyabandara,Gordon McDonald,K. S. Hardman,C. D. Quinlivan,P. Manju,Carlos C. N. Kuhn,Ian R. Petersen,Andre N. Luiten,Joseph Hope,Nicholas Robins,Michael R. Hush +14 more
TL;DR: In this article, an online optimization process based on machine learning is applied to the production of Bose-Einstein condensates (BEC), which is typically created with an exponential evaporation ramp that is optimal for ergodic dynamics with two-body s-wave interactions and no other loss rates, but likely suboptimal for real experiments.
Journal ArticleDOI
Long-distance frequency dissemination with a resolution of 10(-17).
Christophe Daussy,Olivier Lopez,Anne Amy-Klein,Andrei Goncharov,M. Guinet,Christian Chardonnet,F. Narbonneau,Michel Lours,D. Chambon,Sébastien Bize,André Clairon,Georgio Santarelli,Michael E. Tobar,Andre N. Luiten +13 more
TL;DR: The link is used to compare the microwave reference and a CO2/OsO4 frequency standard that stabilizes a femtosecond laser frequency comb, demonstrating a resolution higher than the stability of the best microwave or optical clocks.
