In this paper we propose an information encoding method based on a segmented vortex beam. The segmented vortex beam with a single uniform-intensity ring and a combination of multiple topological charges is designed for information encoding. The radius of the beam can be designed to be arbitrary, with multiple orbital angular momentum states superimposed along the ring. We encoded the information into the segmented vortex beam in the transmitting unit for information transmission. Due to the segmented phase structure of the beam, information can be encoded in each segment, and the information capacity is significantly increased. Additionally, enormous combinations of encoded information in the beam can greatly enhance the security of the encoded information. This proposed method has great potential in free-space optical communication.

This paper introduces the Topological Quantum Information Encoding (TQI) method, a novel approach to quantum information processing focused on leveraging the inherent topological properties of quantum states. Traditional methods often struggle with the limitations of qubit entanglement and the difficulty in efficiently encoding and transmitting complex quantum information. TQI addresses these challenges by employing a structured encoding scheme that utilizes topological quantum states to achieve enhanced storage, transmission, and processing capabilities. The paper details the core mechanism of TQI, highlighting its potential to significantly improve the efficiency of quantum information management. We present preliminary results demonstrating the effectiveness of the TQI method in encoding and manipulating quantum states, showcasing its promise for advancing quantum technologies.

Spin (polarization) is widely used in free-space optics, while in photonic integrated circuits (PICs), information is usually encoded in optical route.So a practical way to connect these two encoding methods is necessary for information communication.In this letter, an encoding convertor is designed to connect spin encoding and route encoding.Finite element method is used to calculate the conversion efficiency and extinction ratio of the encoding convertor and the theoretical analyses are also given.Our protocol shows a friendly way to convert optical spin information to route information, which will promote the compatibility of free-space optics and PICs.
