Advances in quantum entanglement purification
Peishun Yan, Lan Zhou, Wei Zhong +1
Since its discovery, the quantum entanglement becomes a promising resource in quantum communication and computation. However, the entanglement is fragile due to the presence of noi…
Device-independent quantum secure direct communication with single photon sources
Lan Zhou, Bao-Wen Xu, Wei Zhong +1
Quantum secure direct communication (QSDC) can directly transmit secrete messages through quantum channel. Device-independent (DI) QSDC can guarantee the communication security rel…
Even- and odd-orthogonality properties of the Wigner D-matrix and their metrological applications
Wei Zhong, Lan Zhou, Cui-Fang Zhang +1
The Wigner D-matrix is essential in the course of angular momentum techniques. We here derive the new even- and odd-orthogonality properties of the Wigner D-matrix which was yet to…
Non-Markovian dynamics of mixed-state geometric phase of dissipative qubits
Wei Guo, Jian Ma, Xiaolei Yin +2
We investigate the geometric phase of a two-level atom (qubit) coupled to a bosonic reservoir with Lorentzian spectral density, and find that for the non-Markovian dynamics in whic…
