Abstract: There are many different classifications of entanglement for multipartite quantum systems, one of which is based on the number of unentangled particles. In this paper, we mainly study the quantum states containing at most $k-1$ unentangled particles and provide several entanglement criteria based on different forms of inequalities which can both identify quantum states containing at most $k-1$ unentangled particles. We show that these criteria are more effective for some states by concrete examples.

We investigate the detection of quantum states containing fewer than $k$ unentangled particles in multipartite quantum systems. Based on calculations about operators, we derive two practical criteria for judging $N$-partite quantum states owning fewer than $k$ unentangled particles.

We show that particle entanglement and field entanglement are actually distinct phenomena that can occur and be observed independently of each other. This conclusion has direct implications for quantum technology which can harness those independent forms of entanglement in practical scenarios.

Classifying many-body quantum states with distinct properties and phases of matter is one of the most fundamental tasks in quantum many-body physics. Here, we propose a new approach called quantum neuronal sensing. We show that our scheme can efficiently classify two different types of many-body phenomena.

Quantum indistinguishability through exchangeable desirable gambles [69.62715388742298]
Two particles are identical if all their intrinsic properties, such as spin and charge, are the same. Quantum mechanics is seen as a normative and algorithmic theory guiding an agent to assess her subjective beliefs represented as (coherent) sets of gambles. We show how sets of exchangeable observables (gambles) may be updated after a measurement and discuss the issue of defining entanglement for indistinguishable particle systems.

Mesoscopic quantum superposition states of weakly-coupled matter-wave solitons [58.720142291102135]
We establish quantum features of an atomic soliton Josephson junction (SJJ) device. We show that the SJJ-model in quantum domain exhibits unusual features due to its effective nonlinear strength proportional to the square of total particle number. We have shown that the obtained quantum state is more resistant to few particle losses from the condensates if tiny components of entangled Fock states are present.

One-photon measurement of two-photon entanglement [0.0]
Entanglement is a fundamental feature of quantum mechanics, considered a key resource in quantum information processing. Standard methods to measure entanglement require detection of both particles. We introduce a method in which detection of only one of the particles is required to characterize the entanglement of a two-particle mixed state.

Fragility of quantum correlations and coherence in a multipartite photonic system [4.687258715561434]
Certain quantum states are well-known to be particularly fragile in the presence of decoherence. It has been conjectured that each of these quantities have various degrees of fragility in the presence of decoherence. We experimentally confirm this conjecture by preparing tripartite photonic states and subjecting them to controlled amounts of dephasing.
