New Bipartite Entangled States in Two-Mode Fock Space
In quantum optics, in order to clearly describe the unique nonclassical properties of quantum light fields, physicists usually introduce some quantum...

Properties of quantum coherence and correlations in quasi-entangled coherent states
We investigate the validity of quantum Fisher information (QFI) as a helpful coherence quantifier by drawing a comparison with first-order coherence...

Quantum dialogue mediated by EPR-type entangled coherent states
Talking with each other on the telephone is convenient but insecure because the conversation content can be eavesdropped perfectly. Quantum dialogue...

Improving the probabilistic quantum teleportation efficiency of arbitrary superposed coherent state using multipartite even and odd j-spin coherent states as resource
Quantum teleportation is one of the most important techniques for quantum information secure transmission. Using preshared entanglement, quantum...

New Additivity Properties of the Relative Entropy of Entanglement and Its Generalizations
We prove that the relative entropy of entanglement is additive when at least one of the two states belongs to some specific class. We show that these...

Entanglement as a Method to Reduce Uncertainty
In physics, entanglement ‘reduces’ the entropy of an entity, because the (von Neumann) entropy of, e.g., a composite bipartite entity in a pure...
