This book provides an introduction to the basic ideas and concepts of quantum computation and information for both undergraduate and graduate students. The book starts with the quantum bits and the entangled states which turn out to bring revolutionary ideas in information theory. This book is self-contained and unified in its description of the cross-disciplinary nature of this field. The book aims to provide intuitive and transparent ideas of the subjects, and is not strictly mathematical. Quantum mechanics and mathematical tools (especially, number theory) are explained with many examples...

The physics of nuclear collective motion was pioneered by A Bohr and B R Mottelson 50 years ago. Since then, experimental and theoretical development in this field has been remarkable under the leadership of the Copenhagen group. In the 21st century, a new era has opened up due to the recent developments of experimental facilities, especially radioactive ion beams and large γ-ray arrays. Interest in collective motions is now shared in the research of other quantum many-body systems — for example, microclusters and Bose-Einstein condensation. It is therefore timely and important...
