Basics of Quantum Communication
Year: 2025
Type: article
Abstract: Quantum communication is a technology that uses quantum mechanics and information technology to transmit data securely. It uses qubits, which can exist in multiple states due to superposition, to define classical physics. This property, known as "spooky action at a distance," forms the basis of secure protocols like Quantum Key Distribution. Quantum encryption, like the BB84 protocol, is immune to eavesdropping. Despite challenges, advancements in quantum computing and photonics are paving the way for a new era of secure global communication. The purpose of this paper is to give an overview of the basics of quantum communication, exploring its key principles, technologies, and potential applications while addressing the challenges that lie ahead. As a beginner's guide, it serves to introduce readers to the fascinating and transformative possibilities of quantum information science.
