Current Research

Quantum information is an interdisciplinary field of physics and information science. One of the main goals is to understand the information processing abilities and limits of computation and communication, when information processing devices obey the laws of quantum mechanics --- the so-called quantum information processing (QIP). In contrast, the conventional information science always assumes information processing devices that exist within classical mechanics. We aim to exploit the fundamental differences between classical and quantum mechanics, such as interference and entanglement, to design more efficient algorithms and analyze the necessary information processing resource for their implementation. Our recent research focuses on quantum algorithms for distributed QIP and higher-order QIP. In addition, we investigate the possibility of manipulating physical systems more efficiently by adapting quantum computational algorithms.
