Here we apply cavity ring-down spectroscopy to measure the intensity of a rotational-vibrational transition within the fundamental (1–0) vibrational band of carbon monoxide (CO). Laser measurements were made at a wavenumber near 2206 cm−1 on a sample of CO-in-air with an amount fraction of χCO = 77.6 nmol mol−1. High-precision cavity ring-down spectra were acquired using hybrid amorphous-crystalline mirrors to form the optical resonator and by application of simple and robust laser scanning and control techniques.

We investigate a technique for detecting radio-frequency (RF) electric fields in a Cesium (Cs) vapor cell at room temperature by collecting charge from ionized Rydberg atoms and compare its performance with the established method of electromagnetically induced transparency (EIT). By applying a known RF field, we measure the response from both the electrical (ionization current-based) and optical (EIT-based) readouts. The ionization current-based method yields a sensitivity of 22.4~$\mu$Vm$^{-1}$Hz$^{-1/2}$, while the EIT-based method achieves 3.7~$\mu$Vm$^{-1}$Hz$^{-1/2}$.

Most data generated are averaged heterodyne IQ voltages of a reflectometry of a superconducting cavity dispersively coupled to a transmon qubit, where the phase shift of the cavity probe tone is used to infer the qubit state. These data are collected while performing various parameter sweeps to track the qubit state evolution in response to various stimuli. There is also simulation data used to model qubit state evolution when driven with digital pulses.

Rydberg atoms, due to their large polarizabilities and strong transition dipole moments, have
emerged as powerful electric field sensors. While their capability to detect modulated signals has
been previously demonstrated, these studies have largely been limited to laboratory-generated signals tailored specifically for atomic detection. Here, we extend the practical applicability of Rydberg
sensors by demonstrating the reception of real-world frequency-modulated (FM) audio transmissions

This dataset contains results from a 2023-2024 survey of small manufacturers disseminated by the Performance of Emerging Technologies Project (PETR) within the Measurement Science for Robotics and Autonomous Systems Program. Data is completely anonymized but includes basic company demographics in addition to questions about specific task types that are currently automated or manual. Short answer responses regarding current automation challenges are also available. Additionally, survey statistics and analysis are included.

Experimental results from conducted interference susceptibility experiments comparing interference impacts from three broad classes of interference waveforms: 1) synthetic 4G frequency division duplexing (FDD) uplink long term evolution (LTE) signals 2) recordings of real 4G FDD uplink LTE emissions from commercial off-the-shelf (COTS) hardware and 3) artificial pulse modulated noise (PMN). Two COTS communication systems were used as victim links, an IEEE 802.11n Wi-Fi link and a point-to-point (PTP) microwave link.
