Since the author conducted researches on quantum remote sensing (QRS) in March 2000 and on quantum spectral imaging and quantum detection in June 2003, some difficulties occur. What’s the basic theory and how to realize the technical application of QRS passive imaging? What’s the basic theory of quantum spectral theory? How to apply quantum light field entanglement state during long-distance quantum detection into use? These question urged the author to research and reflect the basic theory of light quantum (photon) future technology. Therefore, in 2006, the author began to conduct relevant exploration, and proposed the key concept of lightstring theory. Besides, after referring to some theory in modern optics and physics, namely, the optical frequency comb and the string theory, he put forward to make light quantum concept concrete based on the nature of light in lightstring theory , and on which, he proposed the generation mechanism of string-light effect. The past ten years has witnessed some preliminary progress and there will be more discoveries and progress be made in the future. From the research requirements, the paper firstly elaborates the significance of light quantum future technology, as well as its research history and status with the emphasis on its progress. The main content includes the concept of lightstring, its research method and target. Finally, the future study plan is briefly introduced. The author tries to find a new way to study the light in nature, its generation mechanism and theoretical basis for its future technology.

Post-quantum cryptography (PQC) provides the essential cryptographic algorithms needed to secure digital networking systems against future adversaries equipped with quantum computing. This paper reviews the PQC research landscape and identifies open challenges and future directions for the critical transition to PQC in digital networking systems. Building on the NIST standardization process which has hardened the PQC cipher algorithm security, this paper analyzes and describes the recent research on PQC implementations and integrations into scalable and standardized networking systems (Internet, web and cellular networks). We review research on the security, side-channel threats, performances, overheads, and compatibility of PQC ciphers. We also study the research incorporating PQC into the standardized web and cellular networking protocols, ranging from testing the PQC feasibility to proposing protocol solutions and mechanisms to enable PQC. Our study highlights the PQC challenge of large parameter sizes, common across the PQC cipher algorithms, and the research proposing protocol- and system-level mechanisms to address them. Informed by the survey, this paper identifies and highlights the research gaps and future directions to facilitate further research and development for PQC and to secure next-generation digital networking systems.
