Quantum Computing: General Considerations

Luigi Accardi

It is usually claimed that quantum computer can outperform classical computer. Is this statement true? We discuss this issue, not in general, but in the context of the most famous algorithm of quantum computation: Shor's algorithm.

In this paper, the development of quantum computing is generalized, the fundamental principles are discussed, and two typical quantum algorithms are introduced. In addition, in consideration of the difficulties in signal and information processing, the possible applications of quantum computing to the signal and information processing are appointed. Finally, the latest developments of quantum computing are introducted.

Quantum++ is a modern general-purpose multi-threaded quantum computing library and simulator written in C++11 and composed solely of header files. The library is not restricted to qubit systems or specific quantum information processing tasks, being capable of simulating arbitrary quantum processes. The main design factors taken in consideration were the ease of use, portability, and performance.
