Squeezing and QND with cold atoms

Abstract

Cold atomic clouds were used as a nonlinear medium to reduce the quantum noise of a continuous-wave laser field. The cold atoms were placed in a resonant optical cavity. Quadrature squeezing as high as 40% was measured at the output of the cavity.

Cold atoms from a magneto-optic trap have been used as a nonlinear (χ (3) ) medium in a nearly resonant cavity. Squeezing in a probe beam passing through the cavity was demonstrated. The measured noise reduction is 40% for free atoms and 20% for weakly trapped atoms.

Squeezed states in optical cavities: A spontaneous-emission-noise limit

R. E. Slusher, Leo W. Hollberg, Bernard Yurke +2 more

Squeezed states of light have been predicted to be generated by four-wave mixing in cavity configurations. Any noise fields in the cavity can degrade or modify these squeezed states. An experiment using a Na atomic beam as the nonlinear mixing medium shows that spontaneous emission from the excited atoms results in a broadband frequency spectrum of noise in the cavity used for squeezing. The limits this noise places on the observed amount of squeezing and possible techniques for avoiding this noise source are discussed.

Observation of Squeezed States Generated by Four-Wave Mixing in an Optical Cavity

R. E. Slusher, Leo W. Hollberg, Bernard Yurke +2 more

Squeezed states of the electromagnetic field have been generated by nondegenerate four-wave mixing due to Na atoms in an optical cavity. The optical noise in the cavity, comprised of primarily vacuum fluctuations and a small component of spontaneous emission from the pumped Na atoms, is amplified in one quadrature of the optical field and deamplified in the other quadrature. These quadrature components are measured with a balanced homodyne detector. The total noise level in the deamplified quadrature drops below the vacuum noise level.

Polarization Squeezing with Cold Atoms

Vincent Josse, Aurélien Dantan, L. Vernac +3 more

We study the interaction of a nearly resonant linearly polarized laser beam with a cloud of cold cesium atoms in a high finesse optical cavity. We show theoretically and experimentally that the cross-Kerr effect due to the saturation of the optical transition produces quadrature squeezing on both the mean field and the orthogonally polarized vacuum mode. An interpretation of this vacuum squeezing as polarization squeezing is given and a method for measuring quantum Stokes parameters for weak beams via a local oscillator is developed.
