Fitting magnetic field gradient with Heisenberg-scaling accuracy
Yong-Liang Zhang, Huan Wang, Li Jing +2
We propose a quantum fitting scheme to estimate the magnetic field gradient with -atom spins preparing in W state, which attains the Heisenberg-scaling accuracy. Our scheme comb…
Quantum Cloning Machines and the Applications
Heng Fan, Yi-Nan Wang, Li Jing +4
No-cloning theorem is fundamental for quantum mechanics and for quantum information science that states an unknown quantum state cannot be cloned perfectly. However, we can try to…
Quantum network teleportation for quantum information distribution and concentration
Yong-Liang Zhang, Yi-Nan Wang, Xiang-Ru Xiao +4
We investigate the schemes of quantum network teleportation for quantum information distribution and concentration which are essential in quantum cloud computation and quantum inte…
Quantum key distribution based on a quantum retrodiction protocol
Han-Duo Shi, Yi-Nan Wang, Li Jing +3
This paper is withdrawn. We study the quantum key distribution (QKD) protocol based on a quantum retrodiction protocol, namely the so-called mean king problem. The security is anal…
General Quantum Key Distribution in Higher Dimension
Zhao-Xi Xiong, Han-Duo Shi, Yi-Nan Wang +4
We study a general quantum key distribution protocol in higher dimension. In this protocol, quantum states in arbitrary () out of all mutually unbiased bas…
No-compressing of quantum phase information
Yi-Nan Wang, Han-Duo Shi, Li Jing +4
We raise a general question of quantum information theory whether the quantum phase information can be compressed and retrieved. A general qubit contains both amplitude and phase i…
