Single-photon three-qubit quantum logic using spatial light modulators
Nature Communications, 2017 Photons are essential for quantum information processing, but to date only two-qubit single-photon operations have been realized. Here the authors demonstrate experimentally a three-qubit single-photon linear deterministic quantum gate by exploiting ...

Automatic Modal Wavefront Estimation and Correction for Optical Aberration
IEEE Photonics Journal, 2019 Modal estimation of aberration can quantify the amount of aberration, which plays an important role in optical system optimization, aberration correction, and so on. Here, we propose a simple but effective method to find the modal wavefront of aberration.
