Quantum Information: Qubit and Quantum Computer

This lecture covers the concepts of quantum information, including the measurement process, qubits, quantum computers, and quantum entanglement. It explains the probabilistic nature of quantum measurements, the superposition state of qubits, and the unique properties of quantum computers. The lecture also delves into quantum entanglement, where correlated states of qubits defy spatial distance, leading to applications like quantum teleportation and quantum cryptography.
