Accurate vector measurement of residual magnetic fields with a Rb-Xe nuclear-spin magnetometer.

We demonstrate a frequency-referenced vector measurement of weak residual magnetic fields using a hybrid 87Rb-129Xe magnetometer operated in a near-zero-field environment. The magnetic-field magnitude is obtained from the Larmor precession frequency of hyperpolarized 129Xe nuclear spins via free-induction decay (FID) d...

Preselection-Encoded Weak-Value Interferometry for Optical-Rotation Metrology

Optical-rotation measurements benefit from increasing probe photon number, but their performance is often limited by detector saturation and technical noise in the optical readout. Here we introduce preselection-encoded weak-value amplification (PeWVA), in which the quantity of interest is encoded into the probe polari...
