Magnetocardiography (MCG), which uses high-sensitivity magnetometers to record
magnetic field signals generated by electrical activity in the heart, is a noninvasive method …

State-of-the-art magnetic field measurements performed in shielded environments under
carefully controlled conditions rarely reflect the realities of those applications envisioned in …

We build and characterize a dual-species all-optical magnetometer based on a Cs-K hybrid
vapor cell with a paraffin coating. Using the amplitude-modulated Bell-Bloom scheme and …

Electromagnetic induction imaging (EMI) is a contactless, nondestructive evaluation
technique based on sensing the response of a target to oscillating magnetic fields as they …

Experimentally achieving optimal performance of quantum sensors, such as optically
pumped magnetometers, is usually challenging and time consuming due to the complexity …

Cold atom experiments usually need a controllable and low-noise bias magnetic field to
provide a quantization axis. Most labs need home-made stabilization of the field according …

Spin-exchange relaxation-free (SERF) atomic magnetometers operated under a near-zero
magnetic field are used for vector magnetic field measurements with high sensitivity …

We present a system for active noise control of environmental magnetic fields based on a
filtered-x least mean squares algorithm. The system consists of a sensor that detects the …

Optically pumped magnetometers (OPMs) have developed rapidly in the bio-magnetic
measurement field, which requires lasers with stable frequency and intensity for high …

Optically-dense alkali-metal vapor cells with low optical losses are widely used in quantum
precision measurements, yet atomic behaviors in coated cells still need further study. We …
