This paper presents monogamy relations for three-qubit quantum states by using convex-roof extended negativity, which inspires studying the difference between the three entanglement measures, concurrence, negativity a...

We show that although we cannot distil a singlet frora many pairs of bound entangled states, the concurrence and the tangle of two entangled quantum states are always strictly larger than those of one of them, even bo...

The aim of this paper is to study the adjoint action for the quantum algebra Uq(f(K, H)), which is a natural generalization of quantum algebra Uq(sl2) and is regarded as a class of generalized Weyl algebra..The ...
