Secure quantum communication using trusted third party

A quantum internet is one of the promises of the second quantum revolution. New difficulties arise when the first quantum network (QN) hardware prototypes get closer to completion. The development of scalable QN systems is still in its early stages, yet a functioning network is more than simply the physical tools. The proposed method offers a QN protocol that addresses the novel conceptual and technological difficulties posed by quantum physics and enables end-to-end quantum communication. As the key procedure in quantum information science, quantum entanglement swapping (QES) has the potential to revolutionise QN communication. The suggested paradigm, which considers entanglement, enables safe communication utilising a trusted third party across a long-distance QN. The protocols might act as the basic structure of a future quantum internet. Even if scaling and entanglement coherence issues must be overcome, this research provides the groundwork for improving error-correcting codes and fault-tolerant quantum computers.
