The paper is the first to introduce the data sorting (<span>Dsorting</span>) framework, using entanglement within multiparty quantum contexts to distribute <span>Dsorting</span>. By combining QKD protocols with MPC methodologies, the system ensures that, together with privacy-preserving <span>Dsorting</span>, secure key exchanges are guaranteed. Grover's search algorithm combined with entanglement-based QKD is used and augmented by qudit quantum states to increase security and robustness against errors. The main parts are phase encoding, quantum error correction (QEC), GHZ state preparation, and multiparty entanglement purification. Grover's oracle and privacy amplification provide quantum security for the <span>Dsorting</span> process, and quantum sorting (<span>Qsort</span>) simulates sorting. Experimental results demonstrate sorting accuracy of up to 98% and effective key distribution rates of up to 92%, even under quantum bit error rate (QBER) conditions. Sorting time scales logarithmically with the size of the datasescales logarithmically with the size of the dataset and party count<span>(mathcalligra{n})</span>; <span>(mathcalligra{n})</span>-party entanglement forces higher communication complexity compared to the traditional MPC.

In this study, we propose a Differential Transform Method (DTM) that transforms highly nonlinear governing equations into a solvable system of algebraic equations, thereby overcoming the limitations of conventional numerical approaches. A significant novelty of the method is its ability to provide both analytical insight and computational efficiency, making it an ideal alternative for solving complex heat transfer problems. Thorough analysis is conducted on the thermal characteristics of the fin in relation to critical physical parameters, such as the modified Rayleigh number, radiation-conduction parameter, convection parameter, and Hartmann number. The proposed method’s reliability and accuracy are demonstrated through validation against existing numerical and analytical solutions. A MATLAB-based technique is also provided to facilitate real-world implementations. For the accurate and effective thermal design of extended surfaces in sophisticated engineering systems, this framework offers a new tool.</p></div>","PeriodicalId":597,"journal":{"name":"International Journal of Theoretical Physics","volume":"64 9","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145037151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, we propose a scheme for teleporting an arbitrary unknown two-qubit entangled state via two three-dimensional maximally entangled two-qutrit states as the quantum channel. In this scheme, the sender performs two non-symmetric basis measurements on his own particles, and the receiver must make relevant unitary operation against the sender’s different measurement results to recover the original unknown state. Then, the above maximally entangled quantum channel is replaced by two high-dimensional non-maximally entangled two-particle states, the arbitrary unknown two-qubit state is teleported in such a way that it can be probabilistically reconstructed through introducing auxiliary qubit and performing appropriate operations. We give the success probability of the schemes, and the analysis shows that the scheme based on non-maximally entangled channel is a generalization of the previous scheme. Furthermore, the above schemes can be directly generalized to the case of two arbitrary high-dimensional entangled two-particle states acting as the quantum channel.</p></div>","PeriodicalId":597,"journal":{"name":"International Journal of Theoretical Physics","volume":"64 9","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145021700","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
