“…In the quantum Internet, several entangled paths (paths formulated by several entangled connections) could exist between a given source-target quantum node pair [1,5,6,[47][48][49][50][51][52][53][54][55][56][57][58][59][60][61][62][63][64]. This fact allows us to introduce a method that utilizes this multipath property to change these critical parameters via the number of entangled paths associated with a given end-to-end node pair: the available fidelity of entanglement and the probability of an entangled connection.…”

Quantum entanglement is a crucial element of establishing the entangled network structure of the quantum Internet. Here we define a method to achieve controlled entanglement access in the quantum Internet. The proposed model defines different levels of entanglement accessibility for the users of the quantum network. The path cost is determined by an integrated criterion on the entanglement fidelities between the quantum nodes and the probabilities of entangled connections of an entangled path. We reveal the connection between the number of available entangled paths and the accessible fidelity of entanglement and reliability in the end nodes. The scheme provides an efficient model for entanglement access control in the experimental quantum Internet.1. We define a method to achieve controlled entanglement accessibility in the quantum Internet.2. The algorithm defines entangled paths between the source and target nodes in function of a particular path cost function.3. The path cost is determined by an integrated criterion on the entanglement fidelity and the probability of entangled connection. 4.The proposed scheme has moderate complexity, providing an efficient entanglement accessibility differentiation, allowing for the construction of different priority levels of entanglement accessibility for users. 5.The results can be straightforwardly applied in the entangled quantum networks of the quantum Internet.This paper is organized as follows. In Section 2, the basic components of the model are summarized. In Section 3, the entanglement accessibility methods are discussed. Section 4 proposes

“…where Ψ is a shared Bell pair between the final stations, while ρ f is the input density matrix of R. For an L l -level entangled link E L l (A, B) with hop-distance d(A, B) L l =2 l−1 between final stations A and B and per-node error probability P err (that includes the effective logical error probability Q and other residual errors ε res in the nodes) in the d(A, B) L l +1 total stations, after some calculations the entanglement fidelity (56) can be rewritten as [20]…”

We define the entanglement-gradient routing scheme for quantum repeater networks. The routing framework fuses the fundamentals of swarm intelligence and quantum Shannon theory. Swarm intelligence provides nature-inspired solutions for problem solving. Motivated by models of social insect behavior, the routing is performed using parallel threads to determine the shortest path via the entanglement gradient coefficient, which describes the feasibility of the entangled links and paths of the network. The routing metrics are derived from the characteristics of entanglement transmission and relevant measures of entanglement distribution in quantum networks. The method allows a moderate complexity decentralized routing in quantum repeater networks. The results can be applied in experimental quantum networking, future quantum Internet, and long-distance quantum communications.
