SECURE DATA TRANSMISSION TECHNIQUES IN QUANTUM COMPUTING NETWORKS

Abstract

: Quantum computing is set to bring about a significant change in safe data transfer by utilising the fundamental principles of quantum physics to completely modify cryptographic systems. This analytical article explores advanced methods for securely transmitting data in quantum computing networks, with a specific focus on quantum key distribution (QKD), quantum encryption, and post-quantum cryptography.

Quantum Key Distribution (QKD) is a significant breakthrough that enables two parties to generate a shared, unpredictable secret key that is exclusive to them. This key may be utilised to encode and decode communications securely. QKD, unlike traditional cryptography systems, use the properties of quantum physics, such as superposition and entanglement, to guarantee the detection of any eavesdropping attempts. This paper investigates different Quantum Key Distribution (QKD) protocols, such as BB84 and E91, by assessing their security assumptions, implementation difficulties, and practical uses. QKD's resilience against both quantum and classical attacks establishes it as a fundamental element of forthcoming secure communication infrastructures.

Quantum encryption enhances the capacity for safe data transfer by employing quantum states to encode information, providing encryption systems that are theoretically impossible to crack. This study examines the progress made in quantum encryption methods, such as quantum bit commitment and quantum oblivious transmission, and emphasises their significance in improving privacy and security in quantum networks. An analysis is conducted on the incorporation of quantum encryption into current communication protocols, with a focus on the advantageous collaboration and technical challenges.
