Quantum information masking（QIM） is a crucial technique for protecting quantum data from being accessed by local subsystems. In this paper, we introduce a novel method for achieving1-uniform QIM in multipartite systems utilizing a Fourier matrix. We further extend this approach to construct an orthogonal array with the aid of a Hadamard matrix, which is a specific type of Fourier matrix. This allows us to explore the relationship between 2-uniform QIM and orthogonal arrays. Through this framework, we derive two distinct 2-uniform quantum states,enabling the 2-uniform masking of original information within multipartite ***, we prove that the maximum number of quantum bits required for achieving a2-uniformly masked state is 2~n-1, and the minimum is 2n-1+ 3. Moreover, our scheme effectively demonstrates the rich quantum correlations between multipartite systems and has potential application value in quantum secret sharing.

Dear Editor,Industrial Internet of things(IIoT) is a typical application of cyberphysical system(CPS). In the IIoT, wireless communication is an inevitable trend to replace the deployment-limited wired transmission for cases with large-scale and mobile devices. However, wireless communication gives rise to critical issues related to physical security, such as malicious detections and attacks [1].

Various chemical irrigants and drugs have been employed for intra-canal disinfection in root canal therapy (RCT). However, due to the complexity of root canal anatomy, many drugs still exhibit poor penetrability and antibiotic resistance, leading to suboptimal treatment outcomes. Thus, it is challenging to remove the organic biofilms from root canals. In recent years, light-responsive therapy, with deeper tissue penetration than traditional treatments, has emerged as an effective RCT modality. Herein, this review summarizes the recent development of light-responsive nanomaterials for biofilm removal in *** light-responsive nanomaterials and the corresponding therapeutic methods in RCT, including photodynamic therapy (PDT), photothermal therapy (PTT), and laser-activated therapy, are highlighted. Finally,the challenges that light-responsive nanomaterials and treatment modalities will encounter to conquer the biofilm in future RCT are discussed. This review is believed to significantly accelerate the future development of light-responsive nanomaterials for RCT from bench to bedside.
