Asymptotically Optimal Prepare-Measure Quantum Key Distribution Protocol
Quantum key distribution (QKD) could be the most significant application of quantum information theory. In nearly four decades, although substantial QKD protocols are developed, the BB84 protocol and its varia...

Quantum Key Distribution Over Noisy Channels by the Testing State Method
Quantum key distribution(QKD) might be the most famous application of quantum information theory. The idea of QKD is not difficult to understand but in practical implementations, many problems are needed to be...

Quantum Key Distribution Based on Orthogonal State Encoding
Quantum key distribution(QKD) is one of the most significant areas in quantum information theory. For nearly four decades, substantial QKD schemes are developed. In early years, the security of QKD protocols i...

The Independence of Distinguishability and the Dimension of the System
The are substantial studies on distinguishabilities, especially local distinguishability, of quantum states. It is shown that a necessary condition of a local distinguishable state set is the total Schmidt ran...

Entanglement and nonlocality dynamics of a Bell state and the GHZ state in a noisy environment
We investigate the entanglement and nonlocality dynamics of a two-qubit Bell state and the three-qubit Greenberger–Home–Zeilinger (GHZ) state in a noisy environment by solving analytically a master equation in...
