Experimental progress in atomic, molecular, and optical platforms in the last decade has
stimulated strong and broad interest in the quantum coherent dynamics of many long-range …

In both classical and quantum many-body physics, it is a core issue to characterize statistical
correlations among different degrees of freedom. From this point of view, a natural question …

The standard quantum limit bounds the precision of measurements that can be achieved by
ensembles of uncorrelated particles. Fundamentally, this limit arises from the non …

The control over quantum states in atomic systems has led to the most precise optical atomic
clocks so far,–. Their sensitivity is bounded at present by the standard quantum limit, a …

Spin squeezing is a form of entanglement that reshapes the quantum projection noise to
improve measurement precision. Here, we provide numerical and analytic evidence for the …

Surpassing the standard quantum limit and even reaching the Heisenberg limit using
quantum entanglement, represents the Holy Grail of quantum metrology. However, quantum …

Although entanglement is a key resource for quantum-enhanced metrology, not all
entanglement is useful. For example, in the process of many-body thermalization, bipartite …

The nonequilibrium dynamics of quantum spin models is a most challenging topic, due to
the exponentiality of Hilbert space, and it is central to the understanding of the many-body …

Spin squeezing protocols successfully generate entangled many-body quantum states, the
key pillars of the second quantum revolution. In our recent work [Phys. Rev. Lett. 129 …

Long-range spin-spin interactions are known to generate nonequilibrium dynamics that can
squeeze the collective spin of a quantum spin ensemble in a scalable manner, leading to …
