Introduction With the rapid development of computer networks, the demand for information se-curity is sharply increasing. Quantum cryptography has unconditional security, which WebWith the emergence of classical communication security problems, quantum communication has been studied more extensively. In this paper, a novel probabilistic hierarchical quantum information splitting protocol is designed by using a non-maximally entangled four-qubit cluster state. Firstly, the sender Alice splits and teleports an …

Web27 de abr. de 2024 · The advent of a new kind of entangled state known as hybrid entangled state, i.e., entanglement between different degrees of freedom, makes it possible to perform various quantum computational and communication tasks with lesser amount of resources. Here, we aim to exploit the advantage of these entangled states in communication over … Web4 de jun. de 2009 · In 2010, Wang et al. [15] first proposed a hierarchical quantum information splitting (HQIS) scheme to deal with the situation that the agents are … WebBy utilizing the non-maximally entangled four-qubit cluster states as the quantum channel, we first propose a hierarchical quantum information splitting scheme of arbitrary three-qubit states among three agents with a certain probability. Then we generalize the scheme to arbitrary multi-qubit states. Hierarchy is reflected on the different abilities of agents to … east sandwich ma assessor\u0027s database
