Quantum technologies exploit entanglement to revolutionize computing, measurements, and
communications. This has stimulated the research in different areas of physics to engineer …

Entanglement is an important resource for quantum technologies. There are many ways
quantum systems can be entangled, ranging from the two-qubit case to entanglement in …

We comprehensively review the quantum theory of the polarization properties of light. In
classical optics, these traits are characterized by the Stokes parameters, which can be …

We study the effect of optical polarization squeezing on the performance of a sensitive,
quantum-noise-limited optically pumped magnetometer. We use Bell-Bloom (BB) optical …

Monogamy inequalities for the way bipartite Einstein-Podolsky-Rosen (EPR) steering can be
distributed among N systems are derived. One set of inequalities is based on witnesses with …

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

We discuss quantum variational optimization of Ramsey interferometry with ensembles of N
entangled atoms, and its application to atomic clocks based on a Bayesian approach to …

We determine the complete set of generalized spin squeezing inequalities, given in terms of
the collective angular momentum components, for particles with an arbitrary spin. They can …

We present several inequalities related to the Robertson-Schrödinger uncertainty relation. In
all these inequalities, we consider a decomposition of the density matrix into a mixture of …

A complete set of generalized spin-squeezing inequalities is derived for an ensemble of
particles with an arbitrary spin. Our conditions are formulated with the first and second …
