A Decomposition Method for the Bipartite Separability of Bell Diagonal States
نویسندگان
چکیده
A new decomposition form is introduced in this report to establish a criterion for the bi-partite separability of Bell diagonal states. A such criterion takes a quadratic inequality of the coefficients of a given Bell diagonal states and can be derived via a simple algorithmic calculation of its invariants. In addition, the criterion can be extended to a quantum system of higher dimension. Keywords—decomposition, bipartite separability, Bell diagonal states.

Further Results on the Cross Norm Criterion for Separability
In the present paper the cross norm criterion for separability of density matrices is studied. In the first part of the paper we determine the value of the greatest cross norm for Werner states, for isotropic states and for Bell diagonal states. In the second part we show that the greatest cross norm criterion induces a novel computable separability criterion for bipartite systems. This new cri...
متن کاملBell-states diagonal relativistic multispinor entanglement witnesses in arbitrary dimensions
Two kinds of Bell-states diagonal relativistic multispinor entanglement witnesses (EW) are constructed by using the Euclidean representation of the algebra of Dirac γ matrices in the space-time of arbitrary dimension d, where the first kind can detect some Bell-states diagonal m-partite multispinor bound entangled states in Hilbert space of dimension 2m⌊d/2⌋, including the bipartite relativisti...
متن کاملA Class of Bell Diagonal States and Entanglement Witnesses
We analyze special class of bipartite states – so called Bell diagonal states. In particular we provide new examples of bound entangled Bell diagonal states and construct the class of entanglement witnesses diagonal in the magic basis.
متن کاملSeparability and the stella octangula
A geometrical picture of separability of 2× 2 composite quantum systems, showing the region of separable density matrices in the space of hermitian matrices, is given. It rests on the criterion of separability given by Peres [1], and it is an extension of the “Horodecki diagram” [2] and the “stella octangula” described by Aravind [3]. An illustration of which composite quantum states that are s...

Two kinds of Bell-states diagonal (BSD) entanglement witnesses (EW) are constructed by using the algebra of Dirac γ matrices in the space-time of arbitrary dimension d, where the first kind can detect some BSD relativistic and non-relativistic m-partite multispinor bound entangled states in Hilbert space of dimension 2m⌊d/2⌋, including the bipartite Bell-type and iso-concurrence type states in ...
