Abstract
Non-classical light is a critical resource for a broad range of quantum technologies and fundamental science. However, leading platforms such as laser-cooled atoms and solid-state systems both present substantial challenges to scalability due to complexity and spectral drift. Here, we demonstrate a hybrid approach using a chip-scale rubidium beam coupled to a high finesse cavity-QED system. Specifically, we generate non-classical light and observe optical nonlinearities at the few photon level. This is achieved without degradation of the cavity-QED system. By demonstrating the compatibility of these two technologies, we open a path for distributed sources of non-classical light and set the stage for using cavity-QED to enhance the performance of chip-scale magnetometers and atomic clocks.

Files are named according to the following naming convention: Fig'ASSOCIATED SUBFIGURE.csv'. See the explanation below:
'[ASSOCIATED SUBFIGURE]` references the subfigure of the manuscript where the data is plotted. This repository contains data from 'Fig1', 'Fig2', 'Fig3', and 'Fig4', which are the four figures containing experimental data. All of these figures contain sub-panels which are labeled alphabetically. For example, data from Fig. 2, panel C is referenced by 'Fig2C'. Two subfigures (Fig. 4, panel C and Fig. 4, panel E) compare simulation results to experimental data with 2-D datasets, so the simulation, experimental data, and errors on the experimental data are separated into different files for these subfigures (with 'Data', 'Sim', or 'Error' appended to the filename, respectively).
For one-dimensional data:
Data in each file is separated into columns. They represent x, y-coordinate value of each data point or corresponding error bars. They are labeled according to the following naming convention: '[PARAMETER]_[COORDINATE/ERRORBAR]'. See the explanation below:
'[PARAMETER]' refers to the parameter distinguishing different traces in a subfigure. For all the simulation results presented in the paper, '[PARAMETER]_[COORDINATE/ERRORBAR]' is further appended by '_sim'. For example, in Fig. 3, panel B, there are three different traces: the experimental data for g(2)(tau), the 'linear scatterer' simulation, and the MCWF simulation of g(2)(tau). These are labeled as g2_x, g2_y, LinearScat_x_sim, LinearScat_y_sim, MCWFg2_x_sim, MCWFg2_y_sim.
'[COORDINATE/ERRORBAR]' denotes the x, y-coordinates of the data or the associated error bars. Concretely, 3 types of data are recorded:
- x: x-coordinate of the data in that trace.
- y: y-coordinate of the data in that trace.
- yerror: error bars associated with each y-data point in that trace.
For two-dimensional data:
Data in each file is arranged in a two-dimensional array. Each of these arrays is a normalized two-dimensional histogram of photon detection times. The first row and first column designate the center of the time bins that are used in the histogram, corresponding to the x and y axes of the plot in the figure.
The data is expressed in the same units present in the figures. For completeness, we describe the units here:
- All detuning frequencies are recorded in 'MHz'.
- Temperature is recorded in 'C'.
- Vapor pressure is recorded in 'mTorr'.
- Fractional transmission is normalized to '[0,1]'.
- Photon detection/correlation times t are recorded in units of 'ns'.
- Correlation functions such as g(2) and g(3) are unitless.
- Effective atom number Neff is unitless.
- Fluorescence is recorded in 'nW'.
- All error bars represent the standard error of the mean for the relevant quantity.
Code/software
Figures were generated and data processing was done using Python. Simulations were performed using QuTiP. All data can be opened in any program that can open a .csv file, such as Microsoft Excel.
