Additivity of entanglement of formation for some special cases
Heng Fan
The proof of additivity of entanglement of formation for some special cases is given. The strong concavity of von Neumann entropy due to strong subadditivity of von Neumann entropy…
A note on separability criteria for multipartite state
Heng Fan
The recent proposed realignment separability criterion for mixed is analyzed. We identify the essential part of this criterion is a swap operator followed by a partial transpositio…
A simple way to detect the state transition caused by the nondiagonal abelian Berry phase
X. B. Wang, K. Matsumoto, H. Fan +2
In a nondegenerate syste, the abelian Berry's phase will never cause transitions among the Hamiltonian's eigenstate. However, in a degenerate syatem, it is well known that the stat…
A universal cloner allowing the input to be arbitrary states in symmetric subspace
Heng Fan, Keiji Matsumoto, Xiang-Bin Wang +2
A generalized universal quantum cloning machine is proposed which allows the input to be arbitrary states in symmetric subspace. And it reduces to the universal quantum cloning mac…
A quantum-copying machine for equatorial qubits
Heng Fan, Xiang-Bin Wang, Keiji Matsumoto
Bužek and Hillery proposed a universal quantum-copying machine (UQCM) (i.e., transformation) to analyze the possibility of cloning arbitrary states. The UQCM copies quantum-mechani…
Bethe ansatz for the one-dimensional small-polaron model with open boundary conditions
Heng Fan, Xi-Wen Guan
The one-dimensional small-polaron model with open boundary conditions is considered in the framework of the quantum inverse scattering method. The spin model which is equivalent to…
