| Research Abstract |
In this research, I studied the fundamentals of quantum computers which are based on quantum physics and are expected as a candidate of powerful new-generation computers, especially from the viewpoint of quantum algorithms specialized to the quantum computers. First, I focused on quantum information theory that is a base of quantum computation, and obtained some research results on quantum state discrimination problems and on characterizations of quantum bits from physical principles. On the other hand, I investigated Hidden Subgroup Problems(HSPs) which are one of the main research topics in the area of quantum algorithms ; I revisited the known approaches to HSPs and analyzed drawbacks of these approaches, which will be future research subjects.
