Abstract

We use narrow-band quantum light sources, tuned to the rubidium D1 resonance, to produce polarization-squeezed and polarization-NooN states for Heisenberg-limited measurements on atoms. By paramagnetic Faraday rotation these states measure the atomic spin polarization.

Simultaneous observation of super-Heisenberg scaling and spin squeezing in a nonlinear measurement of atomic spins

R. J. Sewell, M. Napolitano, N. Behbood +3 more

Techniques for making quantum-limited nonlinear measurements have attracted a great deal of recent attention because they allow a measurement sensitivity that improves as the number of measuring particles (e.g. photons) increases faster than an equivalent linear measurement. This super-Heisenberg scaling was recently demonstrated in a proof-of-principle experiment [1], in which a measurement Hamiltonian of the form studied in Ref. [2] was carefully engineered by exploiting nonlinearities in a Faraday rotation based measurement of atomic spins. However, despite the improved scaling, the absolute measurement sensitivity in this experiment remained significantly worse than a linear Faraday rotation measurement due to the weak atom-light coupling strength of the nonlinear Faraday rotation, and effect of higher-order nonlinearities at large photon number. This leaves open the question of whether it is possible to make a nonlinear measurement that both benefits from the improved scaling, and competes in absolute sensitivity with linear techniques.

Ultranarrow Faraday rotation filter for creating narrowband atom-resonant entangled photon pairs

Joanna A. Zielińska

[ANGLÈS] We describe experimental results on a novel optical filter based on the FADOF (Faraday Anomalous Dispersion Optical Filter) principle, and its application to production of atom-resonant entangled photon pairs at the D_1 line of atomic rubidium. The filter uses natural-abundance rubidium vapor in an axial magnetic field to produce Faraday rotation up to pi/2 in the transparent regions adjacent to Rb absorption features. When the Faraday rotator is placed between crossed polarizers, the resulting system shows a 400 MHz FWHM transmission window with 70% peak transmission, and out-of-band rejection up to 10^5. Using this device we demonstrate selection of atom-resonant photon pairs from a type-I cavity-enhanced spontaneous parametric downconversion source (CESPDC). We also present an exact calculation of the time correlations, i.e., the g^(2)(T), of photons from the CESPDC. This is the first time fully-indistinguishable atom-resonant photon pairs have been observed.

Quantum nondemolition measurement of spin via the paramagnetic Faraday rotation

Yoshiro Takahashi, Keita HONDA, N. Tanaka +3 more

We propose a method for quantum nondemolition (QND) measurement of one component of spin by the measurement of polarization rotation of the off-resonant light induced by a paramagnetic Faraday rotation effect. We show that nonclassical states of spins such as the squeezed spin state, the Dicke state, and macroscopic quantum superposed state of spin can be realized corresponding to particular results of QND measurements. Furthermore, it is shown that a nonclassical state of light such as the twin photon state can also be realized with this method.
