Regulations on the Management of the Qualification to Engage in the Business Operations concerning Shares Owned by Foreign Investors

With a view to standardizing the business operationsrelating to foreign investment of domestic and overseas secu-rities organizations and protecting the legitimate rights andinterests of investors,the China Security Regulatory Commis-sion has promulgated the Provisional Regulations on theManagement of the Qualification of Domestic and OverseasSecurities Organizations to Engage in the Business Opera-tions concerning Shares Owned by Foreign Investors.TheseRegulations enter into force on December 1.1996.The wholetext is as follows:Chapter 1 General PrinciplesArticle 1 With a view to standardizing the businessoperations of domestic and overseas securities organizationswhich relate to shares owned by foreign investors and pro-

Single-Qubit Operation Sharing with Bell and W Product States

Two tripartite schemes are put forward with shared entanglements and Local Operation and Classical Communication (LOCC) for sharing an operation on a remote target sate.The first scheme uses a Bell and a symmetric W states as quantum channels,while the second replaces the symmetric W state by an asymmetric one.Both schemes are treated and compared from the aspects of quantum resource consumption,operation complexity,classical resource consumption,success probability and efficiency.It is found that the latter scheme is better than the former one.Particularly,the sharing can be achieved only probabilistically with the first scheme deterministically with the second one.

A potential application in quantum networks-Deterministic quantum operation sharing schemes with Bell states

In this paper, we propose certain different design ideas on a novel topic in quantum cryptography — quantum operation sharing(QOS). Following these unique ideas, three QOS schemes, the "HIEC"(The scheme whose messages are hidden in the entanglement correlation), "HIAO"(The scheme whose messages are hidden with the assistant operations) and "HIMB"(The scheme whose messages are hidden in the selected measurement basis), have been presented to share the single-qubit operations determinately on target states in a remote node. These schemes only require Bell states as quantum resources. Therefore, they can be directly applied in quantum networks, since Bell states are considered the basic quantum channels in quantum networks. Furthermore, after analyse on the security and resource consumptions, the task of QOS can be achieved securely and effectively in these schemes.
