In terms of the relation between the state and its reduced states, we obtain two inequalities which are valid for all separable states in infinite-dimensional bipartite quantum systems. One of them provides an entanglement criterion which is strictly stronger than the computable cross-norm or realignment (CCNR) criterion. 
Bound Entanglement for Bipartite and Tripartite Quantum Systems
We construct bound entangled states in bipartite systems and tripartite systems. A class of bound entangled states in 3k⊗3k quantum systems is constructed. Moreover, we construct a class of entangled
The generalized partial transposition criterion for infinite-dimensional quantum systems
The positive partial transposition (PPT) criterion and the realignment criterion constitute two of the most important criteria for detecting entanglement. The generalized partial transposition (GPT)
Indecomposability of entanglement witnesses constructed from any permutations
We present a way to construct indecomposable entanglement witnesses from any permutations π with π2 ≠ id for any finite dimensional bipartite systems. Some new bounded entangled states are also
Efficient Entanglement Concentration for Arbitrary Less-Entangled N-Atom GHZ State
In this paper, we put forward an effective ECP for arbitrary less-entangled N-atom GHZ state with the help of the photonic Faraday rotation. In our protocol, we only require one pair of
Separability of Tripartite Quantum States with Strong Positive Partial Transposes
The definition of quantum states with strong positive partial transpose (SPPT) in bipartite systems was presented in Phys. Rev. A 77, 022113, 2008 and the separability of super SPPT was studied in J.
Monogamy of entanglement without inequalities
We provide a fine-grained definition for monogamous measure of entanglement that does not invoke any particular monogamy relation. Our definition is given in terms an equality, as oppose to
Concentration and distribution of entanglement based on valley qubits system in graphene
AbstractExploiting the optical excitation selection rules in graphene quantum dots, we investigate theoretically the entanglement generation process and entanglement concentration process of valley
Indecomposability of entanglement witnesses
There is no universal EW W so that every entangled state can be detected by W, so constructing as many as possible EWs is important to detect entanglement in states.


Concurrence for infinite-dimensional quantum systems
The concept of concurrence is extended to infinite-dimensional bipartite systems and it is shown that it is continuous and does not increase under local operation and classical communication.
It is shown that, every entangled state in an infinite-dimensional composite system has a simple entanglement witness of the formI + T witha nonnegative number and T a finite rank self-adjoint
A class of inequalities inducing new separability criteria for bipartite quantum systems
Inspired by the realignment or computable cross norm criterion, we present a new result about the characterization of quantum entanglement. Precisely, an interesting class of inequalities satisfied
Sufficient and necessary conditions of separability for bipartite pure states in infinite-dimensional systems
The PHC criterion and the realignment criterion for pure states in infinite-dimensional bipartite quantum systems are given. Furthermore, several equivalent conditions for pure states to be separable
Entanglement detection beyond the computable cross-norm or realignment criterion
Separability problem, to decide whether a given state is entangled or not, is a fundamental problem in quantum information theory. We propose a powerful and computationally simple separability
Computable Cross-norm Criterion for Separability
We describe a computable analytical criterion for separability of bipartite mixed states in arbitrary dimension. The criterion stipulates that a certain norm on the state space (the computable
Positive finite rank elementary operators and characterizing entanglement of states
In this paper, some indecomposable positive finite rank elementary operators of order (n, n) are constructed. This allows us to give a simple necessary and sufficient criterion for the separability
An entanglement criterion for states in infinite-dimensional multipartite quantum systems
In (Phys Lett A, 2002, 297: 4–8) an entanglement criterion for finite-dimensional bipartite systems is proposed: If ρAB is a separable state, then Tr(ρA2) ⩾ Tr(ρ2) and Tr(ρB2) ⩾ Tr(ρ2). In the
A matrix realignment method for recognizing entanglement
This paper develops a very simple method to assess the inseparability of bipartite quantum systems, which is based on a realigned matrix constructed from the density matrix, and gives an estimate for the degree of entanglement of the quantum state.
Separability and Entanglement-Breaking in Infinite Dimensions
In this paper we give a general integral representation for separable states in the tensor product of infinite dimensional Hilbert spaces and provide the first example of separable states that are
