Data-Flow-Based Normalization Generation Algorithm of R1CS for Zero-Knowledge Proof
Chenhao Shi, Hao Chen, Ruibang Liu +1
The communities of blockchains and distributed ledgers have been stirred up by the introduction of zero-knowledge proofs (ZKPs). Originally designed to solve privacy issues, ZKPs h…
Space-variant polarized Airy beam
Hao Chen, Guoqiang Li
We experimentally generate an Airy beam with polarization structure while keeping its original amplitude and phase profile intact. This class of Airy beam preserves the acceleratio…
Energy flow structuring in the focused field
Hao Chen, Guoqiang Li
We propose an iterative method of energy flow shaping in the focal region with the amplitude, phase and polarization modulation of incident light. By using an iterative optimizatio…
Independent and simultaneous tailoring of amplitude, phase, and complete polarization of vector beams
Hao Chen, Tianxiang Huang, Jianping Ding +1
We present an approach that enables complete control over the amplitude, phase and arbitrary polarization state on the Poincaré sphere of an optical beam in a 4-f system with a spa…
