Abstract: EPR-pairs are crucial in transmitting data qubits over an insecure quantum internet. For sending qubits reliably, a standard method is first to distribute EPR-pairs between a sender and a receiver. After sharing the EPR-pairs, the sender sends the data qubit using quantum teleportation. It shows the importance of EPR-pair distribution in a quantum internet. In this presentation, I will explain how to use the well-known multi-commodity flow-based technique to maximize the total achievable rates for distributing EPR-pairs among multiple source-destination pairs in a network of quantum repeaters while keeping a lower bound on the end-to-end fidelity as a requirement.
