Just as in the pervious five symposia, the aim of this symposium was to link the recent advances in technology with fundamental problems in quantum mechanics. It provided a unique interdisciplinary forum where scientists with different backgrounds were given the opportunity to discuss basic problems of common interest in quantum science and technology from various aspects. This included not only an examination of the topic in terms of quantum optics and mesoscopic physics, but also in terms of the physics of precise measurement, macroscopic quantum phenomena, complex systems, and other fundamental problems in quantum physics. Two new important fields were also dealt with - the field of quantum computing, including quantum teleportation, quantum information, and cryptography, and the field of laser cooling, including Bose-Einstein condensation and atom interferometry.
The resulting proceedings will be welcomed both as a good introductory book on quantum coherence and decoherence by newcomers to the field and as a reference book for experts in this dynamic area.
