Outline of Final Research Achievements

The computational power of the DQC1 model, which is a formalization of non-universal quantum computation with initialization-hard quantum states, is shown to be superior to classical computation. Many quantum distributed algorithms are developed. Under the standard model for distributed algorithms, efficient quantum protocols for several fundamental problems such as the shortest path problem. Secure quantum delegated computation cannot achieve the perfect security for classical clients. By introducing the notion of rewards in quantum computations, classical verification of having the quantum power of the server is affirmatively settled. This is a game-theoretic solution and gives a novel method in quantum computation.

Academic Significance and Societal Importance of the Research Achievements

従来の量子アルゴリズムの研究は,古典的手法に対して量子的手法の優勢性を示すことが中心であった。本研究課題においては,汎用量子コンピュータより早期の実現可能性が高い計算モデルにおける量子超越性を示し,量子分散アルゴリズムという分野を新たに開拓し世界をリードする存在であり,量子計算という研究領域を拡大させている。その意味で学術的に大きく貢献していると考えられる。また,非万能量子計算や量子分散アルゴリズムにおける量子計算は比較的小規模であり,量子計算研究の現実的側面を強調するという意義もある。
