Through the past two decades, we found a possibility of utilizing unique features of quantum mechanics, such as interferences and EPR correlations as tools to manipulate information. Eventually, we realized there are a couple of restrictions on doing this, i.e., "Possibility of Quantum Key. Distribution" and "Impossibility of Quantum Bit Commitment". This paper aims to explain how quantum mechanics imposes such restrictions and what exactly it means for the "interpretation of quantum mechanics", which has been discussed over a century. This paper also proposes a new view point in which quantum mechanics can be interpreted as a theory of information rather than a descriptive theory of physical reality.
