Various modified quantum teleportation schemes are proposed to overcome experimental constraints or to meet specific application requirements for quantum communication. Hence, most schemes are developed and studied with unique methodologies, each with its own inherent challenges. Our research focuses on interconnecting these schemes, which appear to be unrelated to each other, based on the idea that the unique advantages of one scheme can compensate for the limitations of another. In this paper, we introduce an asymptotic teleportation scheme that requires the receiver to complete a classical selection task before performing a quantum correction. This scheme bridges standard teleportation with port-based teleportation through the transformation of joint measurements. Specifically, we categorize and analytically investigate protocols within this scheme for qubit systems. Given that the linear optics teleportation protocol without ancilla qubits is contained in the two non-trivial groups, we provide a novel perspective on its expansion. Furthermore, we discuss the potential application of a protocol from one of these groups as a universal programmable processor and extend these protocols to higher-dimensional systems while maintaining the same properties and potential, providing the analytic form of the joint measurement and its performance. These results thereby propose new avenues for developing a quantum network in higher-dimensional systems.

渐近隐形传态方案桥接标准隐形传态和基于端口的隐形传态



提出了各种改进的量子隐形传态方案来克服实验限制或满足量子通信的特定应用要求。因此,大多数方案都是用独特的方法来开发和研究的,每种方法都有其固有的挑战。我们的研究重点是将这些看似彼此无关的方案互连起来,基于一种方案的独特优势可以弥补另一种方案的局限性的想法。在本文中,我们介绍了一种渐近隐形传态方案,该方案要求接收器在执行量子校正之前完成经典选择任务。该方案通过联合测量的转换将标准隐形传态与基于端口的隐形传态连接起来。具体来说,我们对量子位系统方案中的协议进行分类和分析研究。鉴于没有辅助量子位的线性光学隐形传态协议包含在两个重要组中,我们为其扩展提供了一个新颖的视角。此外,我们讨论了其中一组协议作为通用可编程处理器的潜在应用,并将这些协议扩展到更高维的系统,同时保持相同的属性和潜力,提供联合测量及其性能的分析形式。因此,这些结果提出了在高维系统中开发量子网络的新途径。
