Field-sensitive addressing and control of field-insensitive neutral-atom qubits
N. Lundblad, J. M. Obrecht, I. B. Spielman +1
The establishment of a scalable scheme for quantum computing with addressable and long-lived qubits would be a scientific watershed, harnessing the laws of quantum physics to solve…
Measuring Electric Fields From Surface Contaminants with Neutral Atoms
J. M. Obrecht, R. J. Wild, E. A. Cornell
In this paper we demonstrate a technique of utilizing magnetically trapped neutral Rb-87 atoms to measure the magnitude and direction of stray electric fields emanating from surfac…
Measurement of the Temperature Dependence of the Casimir-Polder Force
J. M. Obrecht, R. J. Wild, M. Antezza +3
We report on the first measurement of a temperature dependence of the Casimir-Polder force. This measurement was obtained by positioning a nearly pure 87-Rb Bose-Einstein condensat…
Measurement of the Casimir-Polder force through center-of-mass oscillations of a Bose-Einstein condensate
D. M. Harber, J. M. Obrecht, J. M. McGuirk +1
We have performed a measurement of the Casimir-Polder force using a magnetically trapped 87-Rb Bose-Einstein condensate. By detecting perturbations of the frequency of center-of-ma…
Alkali adsorbate polarization on conducting and insulating surfaces probed with Bose-Einstein condensates
J. M. McGuirk, D. M. Harber, J. M. Obrecht +1
A magnetically trapped 87Rb Bose-Einstein condensate is used as a sensitive probe of short-range electrical forces. In particular, the electric polarization of, and the subsequent…
Thermally Induced Losses in Ultra-Cold Atoms Magnetically Trapped Near Room-Temperature Surfaces
D. M. Harber, J. M. McGuirk, J. M. Obrecht +1
We have measured magnetic trap lifetimes of ultra-cold Rb87 atoms at distances of 5-1000 microns from surfaces of conducting metals with varying resistivity. Good agreement is foun…
