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…
