Practical Demonstration of Quantum Key Distribution Protocol with Error Correction Mechanism

Abstract

Quantum Key Distribution is a major building block of Quantum cryptography. A Quantum key is generated through the quantum particles. Quantum particles perform operations based on quantum mechanical principles like superposition and entanglement. With these principles, it is not possible for a third party to observe the quantum information. This proves that the Quantum key is highly secured and unbreakable compared to the current existing classical keys. But the major problem observed with quantum information is inbuilt noise which results in high error rates. To overcome this problem, we propose a Quantum key distribution protocol with entanglement purification and asymmetric quantum error correction. With the experiment, we have observed that the proposed method reduces the third-party quantum key detection probability and also increases the quantum key length and communication efficiency by reducing the error rate to 0.04%. © 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
