This book provides an overview on physical realizations of quantum computing by means of molecular systems. It will be useful for graduate students and researchers interested in quantum computing from different areas of physics, physical chemistry, informatics and computer science. Each chapter is written in a self-contained manner and hence can be accessible for researchers and graduate students with even less background in the topics.

Industrial ecology (IE) is a rapidly growing scienti?c discipline that is concerned with the sustainability of industrial systems under explicit consideration of its int- dependence with natural systems. In recent years, there has been an ever-increasing awareness about the applicability of Input-Output Analysis (IOA) to IE, in particular to LCA (life cycle assessment) and MFA (material ?ow analysis). This is witnessed in the growing number of papers at ISIE (International Society for Industrial Ec- ogy) conferences, which use IOA, and also by the installment of subject editors on IOA in the International Journal of Life Cycle Assessment. It can be said that IE has become a major ?eld of application for IOA. The broadening of users of IOA from various backgrounds implies a need for a self-contained textbook on IOA that can meet the needs of students and practitioners without compromising on basic c- cepts and the latest developments. This book was written with the aim of ?lling this need, and is primarily addressed to students and practitioners of IE. As the title suggests, the core contents of the book have grown out of our research in IOA of waste management issues over the last decade. We have been fascinated by the versatile nature of IOA with regard to various technical issues of waste m- agement in particular, and to IE in general. For us (both economists by training), IOA has turned out to be extremely useful in establishing productive communi- tion with scientists and engineers interested in IE.
