The word Quantum is one of the hottest terms since the beginning of this century. Quantum computer, quantum dot TV, quantum communication, quantum battery, quantum dot mobile phone, and quantum printer are gradually becoming the hot terms in our lives. Quantum is not a new concept in physics, as it has been discovered for more than one hundred years. It carries extensive connotations: quantum technologies are deeply changing our present and future lives, the quantum philosophy contains the explanations on the source of substantiality and a brand new world view, and the quantum mechanics may be recognized as the most successful theory in the history of physics. Quantum has become the symbol of our time - at least many people believe that our time belongs to quantum.
