Abstract

We demonstrate atomic filtering of frequency-degenerate photon pairs from a sub-threshold optical parametric oscillator (OPO). The filter, a modified Faraday anomalous dispersion optical filter (FADOF), achieves 70% peak transmission simultaneous with 57 dB out-of-band rejection and a 445 MHz transmission bandwidth. When applied to the OPO output, only the degenerate mode, containing one-mode squeezed vacuum, falls in the filter pass-band; all other modes are strongly suppressed. The high transmission preserves non-classical continuous-variable features, e.g. squeezing or non-gaussianity, while the high spectral purity allows reliable discrete-variable detection and heralding. Correlation and atomic absorption measurements indicate a spectral purity of 96% for the individual photons, and 98% for the photon pairs. These capabilities will enable generation of atom-resonant hybrid states, e.g. “Schrödinger kittens” obtained by photon subtraction from squeezed vacuum, making these exotic states available for quantum networking and atomic quantum metrology applications.

Experimental setup of the OPO, the FADOF filter and detection system. Symbols: PBS: polarizing beam splitter, AOM: acousto-optic modulator, EOM: electro-optic modulator, APD: avalanche photodiode, BD: calcite beam displacer, WP: Wollaston prism, TOF: time-of-flight analyzer, SAS: saturated absorption spectroscopy, VCO: voltage controlled oscillator, PM: polarization maintaining fiber, HWP: half-wave plate, QWP: quarter-wave plate, PD: photodiode

Upper plot: reference transmission spectrum of room temperature natural abundance Rb (blue), filter spectrum (black) and a mirror filter spectrum with respect to the degenerate cavity mode (black dashed). Red shaded regions indicate transmission of correlated photon pairs. Lower plot: cavity output spectrum (blue) and FADOF-filtered cavity spectrum (red). The degenerate cavity mode coincides with the FADOF peak. Both figures have the same frequency scale.

Histograms of arrival time differences for FADOF off compared to theoretical model (both include the background due to accidental coincidences and the artefacts resulting from 1 ns resolution of the counting electronics).

Histograms of the differences of arrival times of the photon pairs for FADOF on (green) and FADOF on with hot cell on the path (black). No background has been subtracted.

Average maxima and minima (dashed lines) and mean value (blue circles) of the noise oscillations detected on the SA due to the laser phase noise, as a function of the variance of the oscilloscope signal proportional to the probe power. The solid lines represent the fitted noise model (brown), a sum of a term linear with power (blue) and shot noise (red).
