Squeezed states of light from an optical parametric oscillator
Squeezed states of the electromagnetic field are generated by degenerate parametric downconversion in a subthreshold optical parametric oscillator. Reductions in photocurrent noise greater than 60% (-4 dB) below the limit set by the vacuum fluctuations of the field are observed in a balanced homodyne detector. A quantitative comparison with theory suggests that the observed noise reductions res...
متن کاملEntanglement in squeezed two-level atom
In the previous paper, we adopted the method using quantum mutual entropy to measure the degree of entanglement in the time development of the Jaynes-Cummings model [1]. In this paper, we formulate the entanglement in the time development of the Jaynes-Cummings model with squeezed states, and then show that the entanglement can be controlled by means of squeezing.
متن کاملOn the bichromatic excitation of a two-level atom with squeezed light
Analytical results for the dynamical evolution of a single two-level atom coupled to an ordinary heat bath and bichromatically excited with two finite bandwidth squeezed fields are presented by solving the Heisenberg equations of motion. Photon statistics of the system in terms of the second-order intensity-intensity correlation function are also discussed. Transient fluorescent intensity as we...
متن کاملSlow and stored light with atom-based squeezed light
In this manuscript we present calculations that consider the propagation of a squeezed vacuum signal field through a resonant atomic medium under electromagnetically induced transparency (EIT). We show that squeezing is degraded due to four-wave mixing processes at high optical depth of the atomic medium. We also present some preliminary results for degenerate Zeeman EIT resonances.
متن کاملSqueezed-light optical magnetometry.
We demonstrate a light-shot-noise-limited magnetometer based on the Faraday effect in a hot unpolarized ensemble of rubidium atoms. By using off-resonant, polarization-squeezed probe light, we improve the sensitivity of the magnetometer by 3.2 dB. The technique could improve the sensitivity of the most advanced magnetometers and quantum nondemolition measurements of atomic spin ensembles.
