Complete orbital angular momentum Bell-state measurement and superdense coding
Ling-Jun Kong, Rui Liu, Zhou-Xiang Wang +9
Quantum protocols require access to large-scale entangled quantum states, due to the requirement of channel capacity. As a promising candidate, the high-dimensional orbital angular…
Near-complete polarization Bell-state analysis based on symmetry-broken scheme with linear optics
Ling-Jun Kong, Yongnan Li, Yu Si +3
Bell-state analysis is a considerable challenge and an essential requirement for reliable implementation of quantum communication proposals. An open question is the one for the max…
Entanglement of Vector-Polarization States of Photons
Ling-Jun Kong, Yongnan Li, Yu Si +4
Photons may have homogeneous polarization and may carry quantized orbital angular momentum (OAM). Photon entanglement has been realized in various degrees of freedom such as polari…
Trajectory-Based Unveiling of Angular Momentum of Photons
Yongnan Li, Zhi-Cheng Ren, Ling-Jun Kong +2
The Heisenberg uncertainty principle suggests that it is impossible to determine the trajectory of a quantum particle in the same way as a classical particle. However, we may still…
Generalized Poincaré Sphere
Zhi-Cheng Ren, Yongnan Li, Si-Min Li +3
We present a generalized Poincaré sphere (G sphere) and generalized Stokes parameters (G parameters), as a geometric representation, which unifies the descriptors of a variety of v…
