A. Saleh1st ed. 2025.Cham :Springer Nature Switzerland :Imprint: Springer,2025.1 online resource (488 pages)Graduate Texts in Physics,1868-45213-031-89120-1 Chapter 1: Bimodal Systems -- Chapter 2: Optical Modes -- Chapter 3: Random Optical Modes -- Chapter 4: Quantum Bits -- Chapter 5: Quantum Information Processing -- Chapter 6: Photons -- Chapter 7: Single-Photon Optics -- Chapter 8: Biphoton Optics -- Chapter 9: Quantum Photonic Sensing.This book introduces classical modal optics and discrete quantum systems using a common mathematical approach based on linear vector spaces. It explores the three key elements of photonic quantum information: the optical bimode, the qubit, and the photon. Both the bimode and qubit are represented as vectors in a two-dimensional linear vector space, but the qubit distinguishes itself through unique properties linked to quantum measurement. While optical bimodes can be mutually coupled, qubits can be entangled, enabling revolutionary quantum information technologies. A single photon occupying a bimode encodes a qubit, facilitating cryptographic protocols for secure communication. When occupying two bimodes, a photon encodes two qubits, enabling local gates. A photon distributed across spatial modes encodes an image. Entangled photon pairs form two qubits, enabling quantum-state teleportation and quantum networks. Additionally, two photons with spatiotemporal modal entanglement form a biphoton, useful for quantum sensing and imaging with sensitivity surpassing classical limits. With numerous illustrations, examples, and exercises, the book is ideal for classroom teaching or self-study at the upper-level undergraduate or beginning graduate level. It also serves as an accessible introduction for readers interested in the foundational principles driving the second quantum revolution and its diverse applications in communication, computing, and metrology.Graduate Texts in Physics,1868-4521OpticsMaterialsPhotonicsOptical engineeringQuantum computersOptical materialsOptics and PhotonicsPhotonic DevicesPhotonics and Optical EngineeringQuantum ComputingOptical MaterialsOptics.Materials.Photonics.Optical engineering.Quantum computers.Optical materials.Optics and Photonics.Photonic Devices.Photonics and Optical Engineering.Quantum Computing.Optical Materials.535Saleh Bahaa E.
