Optical phased array (OPA) is a promising beam-steering device for various applications such as light detection and ranging (LiDAR), optical projection, free-space communication switching. However, the previously reported OPAs suffer from either an insufficiently small number of resolvable points, or complicated control requirement due to extremely large phase shifters. This work introduces nov...

Dicke states are typical examples of quantum with genuine multipartite entanglement. They valuable resources in many information processing tasks, including multiparty communication and metrology. Phased a generalization include antisymmetric basis as special example. These useful atomic molecular physics besides processing. Here we propose practical efficient protocols based on adaptive local ...
