Sunlight-Excited Spontaneous Parametric Down-Conversion for Quantum Imaging
Ye Xing, Deifei Xu, Yuan Li +2
Quantum imaging, which harnesses quantum correlations to achieve imaging with multiple advantages over classical optics, has been in development for several years. Here, we explore…
Polarization Entanglement from Parametric Down-Conversion with a LED Pump
Wuhong Zhang, Diefei Xu, Lixiang Chen
Spontaneous parametric down-conversion (SPDC) is a reliable platform for entanglement generation. Routinely, a coherent laser beam is an essential prerequisite for pumping the nonl…
Imaging hyper-entanglement based on the Hardy-type nonlocality paradox
Wuhong Zhang, Xiaodong Qiu, Dongkai Zhang +1
The concept of quantum entanglement and hyper-entanglement, lying at the heart of quantum information science and technologies, is physically counter-intuitive and mathematically e…
Quantum Information Transfer between a Two-Level and a Four-Level Quantum System
Tianfeng Feng, Qiao Xu, Linxiang Zhou +3
Quantum mechanics provides a disembodied way to transfer quantum information from one quantum object to another. In theory, this quantum information transfer can occur between quan…
Coherent generation of the complete high-dimensional Bell basis by adaptive pump modulation
Yuanyuan Chen, Wuhong Zhang, Dongkai Zhang +2
The Bell basis, a set of maximally entangled biphoton state, is a critical prerequisite towards quantum information processing, and many quantum applications have highlighted the r…
The influence of pump coherence on the generation of position-momentum entanglement in down-conversion
Wuhong Zhang, Robert Fickler, Enno Giese +2
Strong correlations in two conjugate variables are the signature of quantum entanglement and have played a key role in the development of modern physics. Entangled photons have bec…
Influence of pump coherence on the quantum properties of spontaneous parametric down-conversion
Enno Giese, Robert Fickler, Wuhong Zhang +2
The correlation properties of the pump field in spontaneous parametric down-conversion are crucial in determining the degree of entanglement of generated signal and idler photons.…
Making and identifying optical superposition of very high orbital angular momenta
Lixiang Chen, Wuhong Zhang, Qinghong Lu +1
We report the experimental preparation of optical superpositions of high orbital angular momenta(OAM). Our method is based on the use of spatial light modulator to modify the stand…
