Abstract
The study of the quantum state of light, a fascinating area in quantum optics and quantum information science, reveals unique quantum properties. Light, traditionally described classically, manifests these properties at the fundamental level. This chapter explores the essential characteristics and principles governing the quantum state of light, delving into phenomena such as superposition, entanglement, and quantum coherence. We discuss experimental techniques for generating and manipulating quantum states of light, emphasizing their applications in quantum communication, quantum computing, and quantum metrology. The intricate interplay between classical and quantum descriptions of light underscores the significance of understanding and harnessing the quantum nature of this fundamental entity.
