Classical and Quantum Resources in Perfect Teleportation
Zhu Dian, Fulin Zhang, Jingling Chen
We propose a teleportation protocol that enables perfect transmission of a qubit using a partially entangled two-qutrit quantum channel. Within our scheme, we analyze the relations…
Discrimination of Coherent States via Atom-Field Interaction without Rotation Wave Approximation
Jin-Hua Zhang, Fu-Lin Zhang, Mai-Lin Liang +2
The quantum state discrimination is an important part of quantum information processing. We investigate the discrimination of coherent states through Jaynes-Cummings (JC) model int…
Quantum information masking of an arbitrary qudit can be realized in multipartite lower dimensional systems
Wei-Min Shang, Xing-Yan Fan, Fu-Lin Zhang +1
Quantum information masking is a protocol that hides the original quantum information from subsystems and spreads it over quantum correlation, which is available to multipartite ex…

Gang-Gang He, Fu-Lin Zhang
A Maxwell demon can reduce the entropy of a quantum system by performing measurements on its environment. The nonsignaling theorem prevents the demon from affecting the average sta…
Quantum information masking basing on quantum teleportation
Wei-Min Shang, Fu-Lin Zhang, Jing-Ling Chen
The no-masking theorem says that masking quantum information is impossible in a bipartite scenario. However, there exist schemes to mask quantum states in multipartite systems. In…
Locality of three-qubit Greenberger-Horne-Zeilinger-symmetric states
Dian Zhu, Gang-Gang He, Fu-Lin Zhang
The hierarchy of nonlocality and entanglement in multipartite systems is one of the fundamental problems in quantum physics. We study this topic in three-qubit systems considering…
