Binegativity and geometry of entangled states in two qubits
Satoshi Ishizaka
We prove that the binegativity is always positive for any two-qubit state. As a result, as suggested by the previous works, the asymptotic relative entropy of entanglement in two q…

Analytical formula connecting entangled state and the closest disentangled state
Satoshi Ishizaka
The separable state closest to a given entangled state in the relative entropy measure is called the closest disentangled state. We provide an analytical formula connecting the ent…
