A four-party single-qubit operation sharing scheme is put forward by utilizing the Bell and Yeo–Chua product state in an entanglement structure as the composite quantum channel. Four features of the scheme are discussed and confirmed, including its determinacy, symmetry, and security as well as the scheme experimental feasibility. Moreover, some concrete comparisons between our present scheme and a previous scheme [H. Xing et al., Quantum Inf. Process. 13 (2014) 1553] are made from the aspects of quantum and classical resource consumption, necessary operation complexity, and intrinsic efficiency. It is found that our present scheme is more superior than that one. In addition, the essential reason why the employed state in the entanglement structure is applicable for sharing an arbitrary single-qubit operation among four parties is revealed via deep analyses. With respect to the essential reason, the capacity of the product state in quantum operation sharing (QOS) is consequently shown by simple presenting the corresponding schemes with the state in other entanglement structures.

Bell 和 Yeo-Chua 乘积状态下的四方量子操作共享与复合量子通道

利用纠缠结构中的Bell和Yeo-Chua乘积态作为复合量子通道,提出了一种四方单量子比特操作共享方案。讨论并确认了该方案的确定性、对称性、安全性和方案实验可行性等四个特点。此外,我们目前的方案和以前的方案 [H. Xing 等人,Quantum Inf。过程。13(2014)1553]是从量子和经典的资源消耗、必要的操作复杂性和内在效率等方面提出的。发现我们目前的方案比那个方案更优越。此外,通过深入分析揭示了纠缠结构中所采用的状态适用于在四方之间共享任意单量子位操作的本质原因。就本质原因而言,乘积态在量子操作共享(QOS)中的能力因此通过简单地呈现与其他纠缠结构中的状态的相应方案来显示。
