INQNET Seminar

From Quantum Cryptography to Quantum Networks passing through Quantum Error Correction
Nicolò Lo Piparo, National Institite of Informatics, Japan,

Abstract

Quantum cryptography, quantum error correction, and quantum networks can drastically change the way we communicate in the near future. However, their practical implementation is still far from being reached although several attempts have been made. One of the obstacles comes from the big amount of physical resources required to achieve some tasks, such as distributing high fidelity entangled pairs over long distances, increasing the rate of communication, and maintaining a certain level of security. In this talk I will show how we address this issue by applying the quantum multiplexing technique, a novel method that exploits the degrees of a photon to increase the number of qubits carried. I will explain how quantum multiplexing allows to greatly reduce the number of qubits, photons and number of gates when applied to a quantum error correction code. Moreover, I will describe the advantages of combining quantum multiplexing with the quantum aggregation technique for a quantum error correction code. I will finally discuss how quantum multiplexing could potentially be applied to a quantum network system in which the number of qubits increases exponentially with the distance between the nodes of the network.
