style="font-size:12.0pt;font-family:"Times New
Roman","serif";color:black">Squeezed light was
proposed 30 years ago as a way to improve the sensitivity of
gravitational-wave interferometers, and is now being put into
practice in full-scale instruments such as LIGO. Squeezing of
atoms can in principle improve the sensitivity of atomic
instruments such as clocks, gravimeters and optical
magnetometers, although as always "the devil is in the
details.'' Optical magnetometers are particularly interesting
from a quantum mechanical point of view because they combine
an atomic system (the sensor) with an optical system (for
readout). I will discuss recent work to understand the quantum
physics of optical magnetometers, including use of
polarization-squeezed light to improve the sensitivity of a
rubidium-vapor magnetometer and spin squeezing to improve the
sensitivity of a cold-atom magnetometer. As time permits, I
will comment on the new area of nonlinear quantum metrology,
which promises to be particularly important for quantum
enhancement of optical magnetometry.<o:p></o:p></span></p>
