摘要

为了克服实验限制或满足量子通信的特定应用要求,人们提出了各种改进的量子远距离传输方案。因此,大多数方案都是用独特的方法开发和研究的,每种方案都有其固有的挑战。我们的研究重点是基于一种方案的独特优势可以弥补另一种方案的局限性这一理念,将这些看似互不相关的方案相互连接起来。在本文中,我们介绍了一种渐近式远距传输方案,它要求接收器在执行量子修正之前完成经典选择任务。该方案通过联合测量的转换,在标准远距传物与基于端口的远距传物之间架起了桥梁。具体来说,我们对该方案中的协议进行了分类,并对量子比特系统进行了分析研究。鉴于无辅助量子比特的线性光学远距传输协议包含在两个非三维组中,我们为其扩展提供了一个新的视角。此外,我们还讨论了其中一组协议作为通用可编程处理器的潜在应用,并在保持相同特性和潜力的情况下将这些协议扩展到高维系统,提供了联合测量的解析形式及其性能。这些结果为在高维系统中开发量子网络提出了新的途径。

Asymptotic teleportation scheme bridging between standard and port-based teleportation
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.

期刊介绍: Driven by advances in technology and experimental capability, the last decade has seen the emergence of quantum technology: a new praxis for controlling the quantum world. It is now possible to engineer complex, multi-component systems that merge the once distinct fields of quantum optics and condensed matter physics. Quantum Science and Technology is a new multidisciplinary, electronic-only journal, devoted to publishing research of the highest quality and impact covering theoretical and experimental advances in the fundamental science and application of all quantum-enabled technologies.
