This research applies Kalman filtering techniques directly within ultracold atom systems to stabilize magnetic fields using the atoms as intrinsic magnetometers, addressing a critical noise source that limits quantum coherence times. By quantifying the trade-off between measurement precision and atom loss, this work advances control protocols essential for scaling up trapped-ion and neutral-atom qubit architectures.
Kalman Filter Reduces Magnetic Field Drift in Quantum Gas Experiments

A new in situ technique stabilizes magnetic fields in ultracold-atom experiments, using a Kalman filter to eliminate drift up to 70 nT/hr.
Researchers have devised a new method for stabilizing magnetic fields in ultracold atom experiments by utilizing the atoms themselves as a magnetometer. The team, including…
