Quantum Computing in Telecommunications
1. Introduction
Quantum computing is an emerging technology with the potential to revolutionize telecommunications. By leveraging the principles of quantum mechanics, it can enhance information transmission, encryption, and processing capabilities.
2. Key Concepts
2.1 Quantum Bits (Qubits)
Qubits are the fundamental units of quantum information, capable of representing a 0, 1, or both at the same time (superposition).
2.2 Entanglement
Entanglement is a quantum phenomenon where the state of one qubit instantly influences another, regardless of distance.
2.3 Quantum Supremacy
This term refers to the point at which quantum computers can perform computations that classical computers cannot feasibly achieve.
3. Applications
