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…
Minimal sets determining universal and phase-covariant quantum cloning
Li Jing, Yi-Nan Wang, Han-Duo Shi +2
We study the minimal input sets which can determine completely the universal and the phase-covariant quantum cloning machines. We find that the universal quantum cloning machine, w…
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This paper is withdrawn.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…
Unified Universal Quantum Cloning Machine and Fidelities
Yi-Nan Wang, Han-Duo Shi, Zhao-Xi Xiong +4
We present a unified universal quantum cloning machine, which combines several different existing universal cloning machines together including the asymmetric case. In this unified…
