Hierarchical Quantum State Sharing Based on Multi-Parameter Measurements
摘要
Abstract
Fusing the ideas of the hierarchical quantum state sharing and the multi-parameter measurements, a new frame-work is proposed to study the possibilities of Hierarchical Quantum State Sharing(HQSS)in different maximally entan-gled quantum channels. Explicit example of HQSS shows that the proposed framework is possible using 4-qubit cluster state as quantum channel, and this example is the extension of the existing protocol. Considering the challenge of the pres-ervation of the maximally entangled state to the existing techniques, the proposed framework is extended to the case of non-maximally entangled channels. Taking the 4-qubit non-maximally entangled cluster state as an example, it is proved that the extended framework is feasible to study HQSS in different non-maximally entangled channels. Furthermore, the dependences between the success probability(classical consumption)of these examples and the measurement parameters or quantum entanglement parameters are analyzed. It is shown that the parameters of the measurement bases can be adjusted according to the parameters of quantum channel, so as to adjust the probability of success or classical consumption and satisfy the different needs in the real world.关键词
