Quantum-enhanced measurements exploit quantum mechanical effects for increasing the
sensitivity of measurements of certain physical parameters and have great potential for both …

Quantum criticality, as a fascinating quantum phenomenon, may provide significant
advantages for quantum sensing. Here we propose a dynamic framework for quantum …

Quantum metrology pursues the physical realization of higher‐precision measurements to
physical quantities than the classically achievable limit by exploiting quantum features, such …

We address the question of whether the super-Heisenberg scaling for quantum estimation is
indeed realizable. We unify the results of two approaches. In the first one, the original system …

Quantum many-body systems undergoing phase transitions have been proposed as probes
enabling beyond-classical enhancement of sensing precision. However, this enhancement …

Raman-assisted hop** may be used to realize the anyon Hubbard model in one-
dimensional optical lattices. We propose a feasible scenario that significantly improves the …

Quantum critical chains are well-described and understood by virtue of conformal field
theory. Still, the meaning of the real space entanglement spectrum—the eigenvalues of the …

Second order quantum phase transitions, with well-known features such as long-range
entanglement, symmetry breaking, and gap closing, exhibit quantum enhancement for …

We study the quantum phases of bosons with repulsive contact interactions on a two-leg
ladder in the presence of a uniform Abelian gauge field. The model realizes many …
