Summary: This study successfully separates the quantum critical point between different interacting spin phases and achieves the preparation and measurement of squeezed ground states using a novel nonadiabatic technique. The experimental results show that the degree of squeezing in the squeezed ground state gradually decreases over time, which can be well modeled by the tuning of the Hamiltonian due to the loss of atomic density.

Summary: Distinguishability theory is developed to study quantum interference of squeezed vacuum states on unitary linear interferometers, finding that entanglement of photon pairs in Schmidt modes is a source of distinguishability. The distinguishability is quantified by the symmetric part of the internal state of n pairs of photons over spectral Schmidt modes, with probability decreasing exponentially fast as n increases.

Summary: This article presents an analytical quantum theoretic model for nonresonant molecular two-photon absorption of broadband, spectrally multimode squeezed vacuum. The results have implications for the potential use of entangled-light two-photon absorption as a spectroscopic and imaging method. The study finds that bright squeezed vacuum is as effective in driving two-photon absorption as a quasimonochromatic coherent-state pulse in the case of high gain. It is also shown that the two-photon absorption rate is proportional to the second-order intensity autocorrelation function when the final-state linewidth is much broader than the bandwidth of the exciting light. The article discusses the transition between these two limiting cases and the compensation of dispersion in the nonlinear-optical crystal used to generate the squeezed vacuum.

Summary: This study demonstrates a "multiplexed" one-dimensional optical lattice clock that significantly improves the stability and uncertainty of optical atomic clocks by simultaneously querying and parallel reading spatially resolved strontium atom ensembles. It also establishes a miniaturized clock network and prepares heterogeneous ensemble pairs, enabling applications such as precision isotope shift measurements and characterization of clock systematics.

Summary: In high-precision optical measurements, squeezed vacuum states are a promising resource for reducing shot noise.

Summary: The study proposes a new scheme to generate stable spin squeezing without relying on spin-spin coupling or coherent driving on TLSs. By incorporating the mediation role of the common waveguide and squeezed-reservoir engineering technique, the scheme exhibits advantages in the scaling relation of the spin squeezing parameter with the number of TLSs, potentially offering certain advantages in quantum sensing applications.

Summary: This study proposes a scheme to generate squeezed states of magnon and phonon modes and demonstrates the transfer of squeezing between modes of distinct frequencies in a cavity magnomechanical system. By activating the magnetostrictive force in the ferrimagnet, driven magnon mode can be prepared in a squeezed state and transferred to the cavity mode. Parameters for achieving large squeezing of magnons and phonons in different regimes are given as the principal feature of this scheme, which could potentially extend to hybrid optical systems and facilitate strong mechanical squeezing in cavity magnomechanical systems.

Summary: This study investigates the evolution of nonlocal quantum correlations in a correlated channel and proposes a scheme to protect these correlations. The results show that correlation and squeezing effects can prolong the survival time of quantum entanglement, Bell nonlocality, and quantum steering. Local weak measurement and quantum measurement reversal effectively recover the disappeared nonlocal quantum correlations. These findings are important for suppressing decoherence and enhancing quantum correlation.

Summary: This paper investigates the quantum advantages in loss sensing using the two-mode squeezed vacuum state as a probe. By computing the signal-to-noise ratio, it is shown that quantum advantages persist even under strong thermal background noise. Furthermore, an optimum measurement scheme is proposed to demonstrate quantum advantages over the entire range of environmental noise and loss.

Summary: Interactions play a crucial role in controlling the flow of information and creating correlations in many-body quantum systems. By programming non-local interactions in an array of atomic ensembles within an optical cavity, researchers have been able to access effective geometries with different dimensions and topologies than the physical geometry of the array. This work has implications for simulating frustrated magnets, investigating quantum optimization paradigms, and engineering entangled resource states for sensing and computation.

Summary: The research introduces a quantum algorithm using Grover search to solve a class of NP-complete decision problems, providing quantum speedup across a known phase transition in computational complexity. The scheme encodes each problem instance in the couplings of quantum bits to a central spin or boson to realize the oracle without knowledge of the solution, and introduces a scalable recursive algorithm.
