This book presents the basics of quantum information, e.g.,
foundation of quantum theory, quantum algorithms, quantum
entanglement, quantum entropies, quantum coding, quantum error
correction and quantum cryptography. The required knowledge is only
elementary calculus and linear algebra. This way the book can be
understood by undergraduate students. In order to study quantum
information, one usually has to study the foundation of quantum
theory. This book describes it from more an operational viewpoint
which is suitable for quantum information while traditional
textbooks of quantum theory lack this viewpoint. The current book
bases on Shor's algorithm, Grover's algorithm, Deutsch-Jozsa's
algorithm as basic algorithms. To treat several topics in quantum
information, this book covers several kinds of information
quantities in quantum systems including von Neumann entropy. The
limits of several kinds of quantum information processing are
given. As important quantum protocols, this book contains quantum
teleportation, quantum dense coding, quantum data compression. In
particular conversion theory of entanglement via local operation
and classical communication are treated too. This theory provides
the quantification of entanglement, which coincides with von
Neumann entropy. The next part treats the quantum hypothesis
testing. The decision problem of two candidates of the unknown
state are given. The asymptotic performance of this problem is
characterized by information quantities. Using this result, the
optimal performance of classical information transmission via noisy
quantum channel is derived. Quantum information transmission via
noisy quantum channel by quantum error correction are discussed
too. Based on this topic, the secure quantum communication is
explained. In particular, the quantification of quantum security
which has not been treated in existing book is explained. This book
treats quantum cryptography from a more practical viewpoint.
