Course Description

An overview of the quantum information sciences will be given. The topics includes the basic picture of wave/particle duality, quantum key distribution, quantum computation, quantum communication, quantum measurements.


the number of days one has attended, and the score of reports will be considered.

Course Goals

To understand the basic concepts/mechanisms of quantum key distribution, quantum computers, and quantum metrology so that one can read and understand the scientific papers of the related area.

Course Topics

Theme Class number of times Description
Introduction First, we outline the whole lecture and then explain basic concepts such as quantum bit, quantum gate, quantum entanglement etc.
Quantum Computer (Theory) On quantum computation, various quantum algorithms are discussed.
Quantum Computer (Experiment) Quantum information processing is being studied in various physical systems such as photon, ion trap, nuclear spin and the like. We will explain how to realize them.
Quantum Key distribution and Quantum metrology Describe the basic concept of quantum cryptography and quantum measurements and their recent research trends.
Summary and Outlook In addition to summarizing the whole, if time permits, discuss the problems of quantum information science and ethics.


No text book will be used.
