 Quantum information theory

Quantum information theory is a field of study that combines principles from quantum mechanics and information theory to understand how information can be stored, processed, and transmitted using quantum systems. It explores the fundamental limits of information processing and seeks to harness quantum phenomena to improve information technology. Key concepts in quantum information theory include: 1. **Qubits**: The fundamental unit of quantum information, analogous to classical bits but capable of existing in superpositions of states.
