Quantum Fusion of Independent Networks Based on Multi-user Entanglement Swapping
Yiwen Huang, Yilin Yang, Hao Li +7
With the advance development in quantum science, constructing a large-scale quantum network has become a hot area of future quantum information technology. Future quantum networks…
A 15-user quantum secure direct communication network
Zhantong Qi, Yuanhua Li, Yiwen Huang +3
Quantum secure direct communication (QSDC) based on entanglement can directly transmit confidential information. However, the inability to simultaneously distinguish the four sets…
A two-way photonic quantum entanglement transfer interface
Yiwen Huang, Yuanhua Li, Zhantong Qi +3
A quantum interface for two-way entanglement transfer between orbital angular momentum degree of freedom in free space and time-energy degree of freedom in optical fibers, provides…
Spectral compression of single-photon-level laser pulse
Yuanhua Li, Tong Xiang, Yiyou Nie +2
We experimentally demonstrate that the bandwidth of single photons laser pulse is compressed by a factor of 58 in a periodically poled lithium niobate (PPLN) waveguide chip. A chir…
