Photons and Quantum Fluctuations [PDF ebook] 

Based on a special ONR seminar, Photons and Quantum Fluctuations draws together discoveries in nonclassical or "silent" light for research workers and postgraduates in quantum optics. With nonclassical light, noise is reduced in amplitude below that expected by previous applications of the uncertainty principles. Historians of science who wish to ponder the philosophical implications of these developments may also find this a useful volume.
