Quantum optics in phase space

Meer over het boek

This book offers a concise introduction to quantum optics through the lens of phase space, blending modern style with effective pedagogy. It equips students for research with detailed derivations, numerous illustrations, and a variety of problems at the end of each chapter. The theoretical discussions are often paired with corresponding experimental insights, and a comprehensive reference list guides further exploration of the literature. It also serves as a valuable reference for advanced researchers. The author begins with a thorough review of defining experiments in quantum optics and a brief overview of quantum mechanics, using the Wigner phase space distribution function to illustrate quantum state properties. The connection between semi-classical phase space and the Berry phase is explored through WKB wave descriptions, providing insights into wave packet dynamics, fractional revivals, and the Talbot effect. The first half focuses on mechanical oscillators, while the second half delves into the quantization of the radiation field, covering topics like optical interferometry, atom-field interactions, quantum state preparation and measurement, entanglement, decoherence, and atom optics in quantized light fields. This text presents quantum optics in a clear manner, offering extensive references for students to engage with contemporary scientific literature, making it a valuable resource for students, educators, and research
