Complex multi-projective variety and entanglement
Hoshang Heydari, Gunnar Björk
In this paper, we will show that a vanishing generalized concurrence of a separable state can be seen as an algebraic variety called the Segre variety. This variety define a quadri…
Entanglement tensor for a general pure multipartite quantum state
Hoshang Heydari, Gunnar Björk
We propose an entanglement tensor to compute the entanglement of a general pure multipartite quantum state. We compare the ensuing tensor with the concurrence for bipartite state a…
Entanglement measure for general pure multipartite quantum states
Hoshang Heydari, Gunnar Björk
We propose an explicit formula for an entanglement measure of pure multipartite quantum states, then study a general pure tripartite state in detail, and at end we give some simple…
Entanglement criterion for pure bipartite quantum states
Hoshang Heydari, Gunnar Björk
We propose a entanglement measure for pure bipartite quantum states. We obtain the measure by generalizing the equivalent measure for a system, via a $2…
