This paper reviews quantum spin squeezing, which characterizes the sensitivity of a state
with respect to SU (2) rotations, and is significant for both entanglement detection and high …

Some of the most sensitive methods of measuring magnetic fields use interactions of
resonant light with atomic vapour. Recent developments in this vibrant field have led to …

Quantum states of light, such as squeezed states or entangled states, can be used to make
measurements (metrology), produce images, and sense objects with a precision that far …

We present a pedagogical treatment of the formalism of continuous quantum measurement.
Our aim is to show the reader how the equations describing such measurements are derived …

The irreversible evolution of a microscopic system under measurement is a central feature of
quantum theory. From an initial state generally exhibiting quantum uncertainty in the …

Quantum information describes the new field which bridges quantum physics and
information science. The quantum world allows for completely new architectures and …

We demonstrate sub-projection-noise sensitivity of a broadband atomic magnetometer using
quantum nondemolition spin measurements. A cold, dipole-trapped sample of rubidium …

We demonstrate spin squeezing in a room temperature ensemble of≈<? format?> 10 12
cesium atoms using their internal structure, where the necessary entanglement is created …

We demonstrate quantum control of a large spin angular momentum associated with the F=
3 hyperfine ground state of Cs 133. Time-dependent magnetic fields and a static tensor light …

In this review we discuss approaches to numerical modelling of decoherence by a spin bath.
We consider several popular simulation methods, briefly discussing their implementation …
