(Quantum Inf. Process. <b>21</b>, 3 2022) from two-level and three-level quantum systems to high-level quantum system, a definitive three-party quantum state sharing (QSS) protocol in an amplitude damping environment is proposed to distribute an arbitrary unknown single-qudit quantum state. To achieve this goal, we initially propose the detailed steps for sharing a pure entangled three-qudit state as a quantum resource in an amplitude damping environment via entanglement compensation. Then, based on the pure entangled three-qudit state shared among trader and two agents, the secret quantum information of the trader, i.e., an unknown single-qudit quantum state is divided in such a manner that it can be probabilistically reconstructed by one recipient through the introduction of an auxiliary qubit and the application of appropriate unitary operations by the recipient, provided that two other participants cooperate. Subsequently, the above three-party sharing scheme is generalized to the case of multiparty sharing. The findings indicate that the success rate of the recipient in recovering the secret quantum information is solely determined by the smaller of the absolute values of the coefficients that define the quantum channel. In addition, regardless of the noise intensity in the amplitude damping channel, the fidelity of quantum state transmitted in our schemes can always reach 100%, which is impossible for existing QSS schemes in high-dimensional quantum system based on noisy environments.</p></div>","PeriodicalId":597,"journal":{"name":"International Journal of Theoretical Physics","volume":"64 2","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143379764","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}

Recently, concerns about the Dirac density’s validity have arisen due to the Zitterbewegung phenomenon, characterized by a peculiar fast-oscillating solution of the coordinate operator that disrupts the classical relation among velocity, momentum, and energy. To explore this, we applied Newton and Wigner’s method to define proper position operators and their eigenstates in both representations, identifying ’localized states’ orthogonal to their spatially displaced counterparts. Our analysis shows that both densities could represent the probability of locating a particle within a few Compton wavelengths. However, a critical analysis of Lorentz transformation properties reveals that only the Dirac density meets all essential physical criteria for a relativistic probability density. These criteria include covariance of the position eigenstate, adherence to a continuity equation, and Lorentz invariance of the probability of finding a particle. Our results provide a clear and consistent interpretation of the probability density for a massive spin-1/2 particle in relativistic quantum mechanics.</p></div>","PeriodicalId":597,"journal":{"name":"International Journal of Theoretical Physics","volume":"64 2","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143361791","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}
