Recent interest in aspects common to quantum information and condensed matter has
prompted a flurry of activity at the border of these disciplines that were far distant until a few …

The technique of stimulated Raman adiabatic passage (STIRAP), which allows efficient and
selective population transfer between quantum states without suffering loss due to …

We review recent theoretical work on two closely related issues: excitation of an isolated
quantum condensed matter system driven adiabatically across a continuous quantum phase …

What is the relation between spin squeezing and entanglement? To clarify this, we derive
the full set of generalized-spin-squeezing inequalities for the detection of entanglement …

We analyze the entanglement entropy in the Lipkin-Meshkov-Glick model, which describes
mutually interacting spin 1/2 embedded in a magnetic field. This entropy displays a …

The chirality-controlled two-mode Lipkin–Meshkov–Glick (LMG) models are mimicked in a
potential hybrid quantum system, involving two ensembles of solid-state spins coupled to a …

The Lipkin-Meshkov-Glick (LMG) model describes critical systems with interaction beyond
the first-neighbor approximation. Here we address quantum metrology in LMG systems and …

I present methods for detecting entanglement around symmetric Dicke states. In particular, I
consider N-qubit symmetric Dicke states with N/2 excitations. I show that for large N these …

We give a detailed description of the implementation of a Mølmer–Sørensen gate entangling
two 40 Ca+ ions using a bichromatic laser beam near-resonant with a quadrupole transition …

We analyze the entanglement properties of the ground state for a system of spins half
embedded in a magnetic field, mutually interacting antiferromagnetically. Contrary to the …
