The control of individual quantum systems promises a new technology for the 21st century-
quantum technology. This book is the first comprehensive treatment of modern quantum …

This paper provides an introduction to quantum filtering theory. An introduction to quantum
probability theory is given, focusing on the spectral theorem and the conditional expectation …

We study the use of squeezed probe light and evasion of measurement backaction to
enhance the sensitivity and measurement bandwidth of an optically pumped magnetometer …

Measurement of spin precession is central to extreme sensing in physics,, geophysics,
chemistry, nanotechnology and neuroscience, and underlies magnetic resonance …

The engineering and control of devices at the quantum mechanical level—such as those
consisting of small numbers of atoms and photons—is a delicate business. The fundamental …

We report an experimental and theoretical study of spin-noise correlations in a Rb 87-Cs
133 unpolarized alkali-metal vapor dominated by spin-exchange collisions. We observe …

We demonstrate a fast three-axis optical magnetometer using cold, optically trapped 87 Rb
gas as a sensor. By near-resonant Faraday rotation we record the free-induction decay of a …

Polarized atomic vapors can be used to detect fields interacting with a spin. Recent
advances have extended the sensitivity of atomic magnetometers to a level favorable for …

This paper studies a quantum risk-sensitive estimation problem and investigates robustness
properties of the filter. This is a direct extension to the quantum case of analogous classical …

High-precision inertial sensing demonstrations with light pulse atom interferometry have
typically used Raman pulses having durations orders of magnitude shorter than the dwell …
