چکیده
Quantum entanglement is the core resource in quantum information processing and computing. It a significant challenge to effectively characterize of states. Recently, elegant separability criterion presented by Elben et al. (Phys Rev Lett 125:200501, 2020) based on first three partially transposed (PT) moments density matrices. Then, Yu 127:060504, 2021) proposed two general powerful criteria PT moments. In this paper, realignment operations matrices we propose detection terms such We show detailed example that can also be used identify entanglement.

Inseparability criteria based on matrices of moments
Inseparability criteria for continuous and discrete bipartite quantum states based on moments of annihilation and creation operators are studied by developing the idea of Shchukin-Vogel criterion [Phys. Rev. Lett. 95, 230502 (2005)]. If a state is separable, then the corresponding matrix of moments is separable too. Generalized criteria, based on the separability properties of the matrix of mom...
متن کاملOn independent permutation separability criteria
Recently P. Wocjan and M. Horodecki [quant-ph/0503129] gave a characterization of combinatorially independent permutation separability criteria. Combinatorial independence is a necessary condition for permutations to yield truly independent criteria meaning that that no criterion is strictly stronger that any other. In this paper we observe that some of these criteria are still dependent and an...
متن کاملSeparability criteria and entanglement witnesses for symmetric quantum states
We study the separability of symmetric bipartite quantum states and show that a single correlation measurement is sufficient to detect the entanglement of any bipartite symmetric state with a non-positive partial transpose. We also discuss entanglement conditions and entanglement witnesses for states with a positive partial transpose.
متن کاملImproved Separability Criteria Based on Bloch Representation of Density Matrices
The correlation matrices or tensors in the Bloch representation of density matrices are encoded with entanglement properties. In this paper, based on the Bloch representation of density matrices, we give some new separability criteria for bipartite and multipartite quantum states. Theoretical analysis and some examples show that the proposed criteria can be more efficient than the previous rela...
متن کاملA new class of separability criteria for bipartite quantum systems
Abstract. Inspired by the realignment or computable cross norm criterion, we present a new result about the characterization of quantum entanglement. Precisely, a new class of necessary conditions for the separability of bipartite quantum states, that generalize the realignment criterion, are derived. We conjecture that these new conditions — that form an infinite set of criteria — are independ...
