量子網路是量子通訊之基礎，通過量子網路分發量子位元，可以傳遞量子狀態，利用其超越古典的特殊性，實現各種量子通訊上的應用，達成古典通訊所不能及之速度與安全性。然而對於網路的使用者，不一定擁有充份的量子操作能力測試量子網路的可靠性，尤其現今對於量子網路可靠性的測試，大多數依賴對系統進行保真度的量測，甚至需要進行量子斷層掃描來進行完整的分析，對於量子網路，尤其是當系統越大時，進行測試的所需資源及量測時間就會越多。因此我們從使用者的角度出發，發展了可以有效率地偵測量子同調傳遞之理論與實驗技術。透過作為量子網路重要指標之量子同調特性，可以在無需得知整個量子網路中的所有量子特性之情況下，忠實地完成量子網路可靠性之認證於所提出的方案中，我們可以透過最低限度的一組量測基底，以及完成一個簡單之量子同調操作，即可驗證量子網路中量子同調之傳遞。除此之外，我們也在實驗上成功透過光纖傳輸光子的方式實現了六光子糾纏，也發現利用符合計數模組可以加速尋找多光子糾纏的進程，這些成果奠定了日後在實驗上可以實現更複雜方案的基礎。在這篇文章我們也通過在六光子糾纏實驗下模擬量子網路，第一次在實驗上成功地實現本篇介紹的方案，展示其在實驗上的可行性。

Quantum networking serves as the foundation for quantum communication, enabling the distribution of quantum bits (qubits) and the transmission of quantum states. Leveraging its surpassing features compared to classical communication, various applications in quantum communication can be achieved, providing speeds and security beyond what classical communication can attain. However, is not always guaranteed that the quantum network users have sufficient quantum operational capabilities to test the reliability of quantum networks. Particularly, current methods for testing quantum network reliability often rely on measuring the fidelity of the system, and in some cases, even necessitate performing quantum tomography for a comprehensive analysis. As the quantum system increases, the resources and measurement time required for verification also escalate.
Therefore, from the perspective of users, we have developed a theoretical and experimental technique that efficiently detects quantum coherence transmission. By utilizing quantum coherence as an essential indicator for quantum networks, we can faithfully verify the reliability of quantum networks without the need to know all the quantum properties throughout the entire network. In our proposed scheme, a minimal set of measurement bases and a simple quantum coherence manipulation are sufficient to authenticate quantum coherence transmission within the network.
Additionally, in our experiments, we have successfully achieved six-photon entanglement through optical fiber transmission. We also discovered that using coincidence counting modules can expedite the process of finding multi-photon entanglement. These achievements lay the groundwork for implementing more complex schemes in future experiments.
In this article, we also simulate quantum networks based on the six-photon entanglement experiment, demonstrating the feasibility of the proposed scheme in practical experiments for the first time.
