标题： Quantum Shadows: The Dining Information Brokers

摘要： 本文介绍了创新的量子餐饮信息中介问题，提出了一种基于纠缠的量子协议来解决这一问题。该场景涉及$n$个信息中介，它们位于不同的地理区域，参与一种隐喻性的虚拟晚餐。目标是每个中介同时与其他人共享一条独特信息。与之前的方法不同，该协议能够在所有中介之间实现完全并行的单步通信交换，无论它们的物理位置如何。该协议的一个关键特点是能够确保所有参与者的匿名性和隐私性得到保持，这意味着没有任何中介可以识别接收到的信息背后的发送者身份。量子餐饮信息中介问题作为实现分布式系统中匿名、不可追踪和大规模并行信息交换的概念框架。所提出的协议引入了三个重大进展。首先，虽然已经开发出用于一对多同时信息传输的量子协议，但据我们所知，这是最早实现多对多同时信息交换的量子协议之一。其次，它保证了所有发送者的完全匿名性和不可追踪性，这是对顺序应用一对多协议的显著改进，因为后者无法确保如此强大的匿名性。第三，利用量子纠缠，该协议以完全分布式的方式运行，能够适应不同空间位置的中介。这种方法在安全、可扩展和匿名通信方面取得了重大进展，具有在隐私和并行性至关重要的分布式环境中的潜在应用。 显示英文摘要

摘要： This article introduces the innovative Quantum Dining Information Brokers Problem, presenting a novel entanglement-based quantum protocol to address it. The scenario involves $n$ information brokers, all located in distinct geographical regions, engaging in a metaphorical virtual dinner. The objective is for each broker to share a unique piece of information with all others simultaneously. Unlike previous approaches, this protocol enables a fully parallel, single-step communication exchange among all brokers, regardless of their physical locations. A key feature of this protocol is its ability to ensure both the anonymity and privacy of all participants are preserved, meaning no broker can discern the identity of the sender behind any received information. At its core, the Quantum Dining Information Brokers Problem serves as a conceptual framework for achieving anonymous, untraceable, and massively parallel information exchange in a distributed system. The proposed protocol introduces three significant advancements. First, while quantum protocols for one-to-many simultaneous information transmission have been developed, this is, to the best of our knowledge, one of the first quantum protocols to facilitate many-to-many simultaneous information exchange. Second, it guarantees complete anonymity and untraceability for all senders, a critical improvement over sequential applications of one-to-many protocols, which fail to ensure such robust anonymity. Third, leveraging quantum entanglement, the protocol operates in a fully distributed manner, accommodating brokers in diverse spatial locations. This approach marks a substantial advancement in secure, scalable, and anonymous communication, with potential applications in distributed environments where privacy and parallelism are paramount.
