The quest for secure communication in the quantum age has led researchers to explore innovative solutions. One crucial component of this pursuit is entanglement distribution, which enables qubit state transmission through quantum teleportation. However, existing protocols have limitations that hinder their effectiveness. To overcome these challenges, scientists have developed the Ranked Entanglement Distribution Protocol (REDiP), a novel approach that combines entanglement swapping and purification to achieve target end-to-end fidelity. In this article, we delve into the details of REDiP, exploring its capabilities, simulations, and guidelines for configuration. Can this protocol unlock the potential of quantum internet?
Can Quantum Internet Enable Secure Communication?
The concept of entanglement has been a cornerstone of quantum mechanics, allowing for the sharing of information between two or more systems. In the context of a quantum network, entangled qubit pairs are essential for enabling qubit state transmission through quantum teleportation. However, existing protocols for entanglement distribution have limitations that hinder their effectiveness.
One major issue is the fixed swapping order on involved quantum repeaters, which delegates entanglement purification to upper-layer protocols. This limitation becomes problematic when entangled states degrade due to quantum noise and cannot be purified if their fidelity falls below a certain threshold. To overcome these limitations, it is crucial to combine entanglement swapping and purification to achieve a target end-to-end fidelity.
In this article, we present the Ranked Entanglement Distribution Protocol (REDiP), which addresses these limitations by incorporating a ranking mechanism to configure the ordering of both purification and entanglement swapping steps. We demonstrate how REDiP can be easily configured to implement custom entanglement swapping and purification strategies, including those adopted in recent works.
