摘要
在量子信息传输过程中应减少作为量子信道的粒子数并尽量增加传输的信息,保证传输过程的安全和对传输信息过程进行有效控制。提出了一种多维量子编码的可控信息传输方案,首先Alice要和Bob对编码的信息制定一个规范,然后,Alice对粒子做幺正变换,接受者Bob对接收到的粒子进行测量,根据控制者Charlie发来的测量信息就可以知道Alice要传输的信息,这种量子信息传输粒子少,有一个控制者可对传输过程进行控制,所以易于实现,而且保证安全。
In the process of transferring quantum information, it is repuired to reduce the number of particles as the quantum channel and maximize the transmission of information, while the safety and control of the transmission procession must be ensured. A scheme of multi-dimensional quantum superdense coding controlled transmission of information was proposed. At first, Alice and Bob should make a standard for information that would be encoded, then Alice does unitary transformation to particles, Bob measures the received particles and obtains the information that Alice wants to transfer according to the information of Charlie sending. This kind of information transmission requires less transform particles, so it is easier to accomplish. There is a controller to control the transmission process for the safty.
