As part of the online Colloquium series organised by the Centre for Quantum Information, Communication and Computing, we will have a talk by Dr. Kaushik Chakraborty (University of Edinburg) on Tuesday, 18th January at 3.00 pm.

Title: How to Distribute EPR-pairs in a Quantum Internet with the End-to End Fidelity Guarantee

Abstract : The quantum internet is a new kind of communication infrastructure for distributing quantum information among quantum information processing devices. For the last few years, from the government agencies to the private sector, people are showing interest in this relatively new technology. In this presentation, I will talk about this quantum internet and how it differs from the traditional classical internet. Next, I will discuss what are the interesting applications of quantum internet. Later, I will focus more on the routing, and scheduling problems for the quantum network. EPR-pairs play a 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.
