Correlated coherence as resource of remote state preparation and quantum teleportation
Shenghang Li, Yi-Xin Chen
Quantum discord and quantum entanglement are resources in some quantum information processing (QIP) models. However, in recent years, the evidence that separable states or classica…
Deterministic remote preparation of an arbitrary qubit state using a partially entangled state and finite classical communication
Congyi Hua, Yi-Xin Chen
We propose a deterministic remote state preparation (RSP) scheme for preparing an arbitrary (including pure and mixed) qubit, where a partially entangled state and finite classical…
Comparative study of nonclassicality, entanglement, and dimensionality of multimode noisy twin beams
Ievgen I. Arkhipov, Jan Perina, Adam Miranowicz
Nonclassicality, entanglement, as well as dimensionality of a noisy twin beam are determined using characteristic function of the beam written in the Fock basis. One-to-one corresp…
"Almost" Quotient Space, Non-dynamical Decoherence and Quantum Measurement
Yu-Lei Feng, Yi-Xin Chen
An alternative approach to decoherence, named non-dynamical decoherence is developed and used to resolve the quantum measurement problem. According to decoherence, the observed sys…
Optimizing classical communication in remote preparation of a general pure qubit
Congyi Hua, Yi-Xin Chen
How to uses shared entanglement and forward classical communication to remotely prepare an arbitrary (mixed or pure) state has been fascinating quantum information scientists. A co…
Fidelity of remote state preparation can be enhanced by local operation
Congyi Hua, Sheng-Wen Li, Yi-Xin Chen
Remote state preparation (RSP) is a quantum information protocol which allows preparing a quantum state at a distant location with the help of a preshared nonclassical resource sta…
