Quantum correlations are not restricted to the well known entanglement investigated in Bell-type experiments. Other forms of correlations, for example quantum discord, have recently been shown to play an important role in several aspects of quantum information theory. First experiments also support these findings. This book is an introduction into this up-and-coming research field and its likely impact on quantum technology. After giving a general introduction to the concept of quantum correlations and their role in quantum information theory, the author describes a number of pertinent results and their implications.

• Correlations Beyond Entanglement
• Efficiency of Quantum Algorithms
• Geometric Measure of Entanglement
• Geometric Measure of Quantumness
• Measures of Quantum Correlation
• Quantum Computing with Mixed States

“This book introduces to the title problem and represents the present state of art in an instructive and mathematically rigorous manner. It can be well recommended to students, lecturers and researchers on the field of quantum information processing.” (K.-E. Hellwig, zbMATH, Vol. 1326.81007, 2016)
