    Award type:International academic award (Japan or overseas) 

    Francesco Buscemi's results solved some long-standing open problems in the foundations of quantum physics, using ideas from mathematical statistics and information theory. He established, in a series of single-authored papers, the theory of quantum statistical morphisms and quantum statistical comparison, generalizing to the noncommutative setting some fundamental results in mathematical statistics dating back to works of David Blackwell and Lucien Le Cam. In particular, Prof. Buscemi successfully applied his theory to construct the framework of "semiquantum nonlocal games," which extend Bell tests and are now widely used in theory and experiments to certify, in a measurement device-independent way, the presence of non-classical correlations in space and time.

    Language:English   Publisher:IEEE Transactions on Information Theory  

    The guesswork of a quantum ensemble quantifies the minimum number of guesses needed in average to correctly guess the state of the ensemble, when only one state can be queried at a time. Here, we derive analytical solutions of the guesswork problem subject to a finite set of conditions, including the analytical solution for any qubit ensemble with uniform probability distribution. As explicit examples, we compute the guesswork for any qubit regular polygonal and polyhedral ensemble.

    Quantitative studies of irreversibility in statistical mechanics often involve the consideration of a reverse process, whose definition has been the object of many discussions, in particular for quantum mechanical systems. Here we show that the reverse channel very naturally arises from Bayesian retrodiction, in both classical and quantum theories. Previous paradigmatic results, such as Jarzynski's equality, Crooks' fluctuation theorem, and Tasaki's two-measurement fluctuation theorem for closed driven quantum systems, are all shown to be consistent with retrodictive arguments. Also, various corrections that were introduced to deal with nonequilibrium steady states or open quantum systems are justified on general grounds as remnants of Bayesian retrodiction. More generally, with the reverse process constructed on consistent logical inference, fluctuation relations acquire a much broader form and scope.

    今日の量子計算量理論において,対話型証明の概念は非常に大きな存在となっている.一方で,近年その実装へ向けて社会的注目を集める量子コンピュータはまだ小規模であり,量子メモリや量子通信は依然として高コストである.この状況を鑑みて,本研究では量子計算や量子通信が制限された量子対話型証明や量子計算に動機づけられた古典対話型証明,さらにはその中間的な対話型証明モデルに着目し,それらの対話型証明モデルについての計算量理論を展開する.これにより量子コンピュータの検証問題に対する新しい解決法を提案し,既存の量子対話型証明モデルや量子多項式階層理論を俯瞰的に捉えることができるような包括的成果を得ることを目指す.
    まず,量子計算の古典計算機による検証については,古典の計算量理論で2012年から研究されている合理的証明の概念を新たに導入し,量子計算の検証に経済的な概念を導入した.その結果,多項式時間量子計算に対する合理的証明プロトコルを得ることができ,量子計算の古典計算による合理的証明は可能であることを示した.また,Serfling boundに基づく効率的な状態検証プロトコルも提案することができた.通信回数を制約した量子対話型証明については,2005年に提案されたArthur-Merlinゲームの量子版をより一般的な形に拡張して,それらによって検証可能な問題のクラスを提案し,またそれらのクラスに関する完全問題を発見するなど,幾つかの基本的な性質を示すことができた.また分散計算における検証の概念を量子計算にも拡張することを検討し,等価性判定問題の検証について,議論を行った.その結果,等価性判定問題を効率的に検証する量子プロトコルのアイデアを得ることができた.他にも関連研究として量子計算量理論,量子アルゴリズム,量子情報理論に関する数多くの成果を得ることができた.量子計算量理論については,Fine-grained complexity theoryにおける仮定に基づき指数時間であっても古典シミレートできない量子回路を明らかにした.量子アルゴリズムについては,グラフ上の三角形を発見する問題や All-Pairs Shortest Path problemと呼ばれる最短路のペアを見つける問題において,古典よりも高速な量子アルゴリズムを得ることができた.
    初年度から量子計算の検証や通信回数を制限した対話型証明に関して成果が得られ,関連する量子計算量理論,量子アルゴリズム,量子情報理論の成果も数多く得られたことによる.一方で,分散計算における検証の量子版の研究は想定より解析が困難であり,さらには新型コロナの影響もあって外部発表には至らなかった.
    引き続き,量子計算の検証や通信回数を制限した量子対話型証明,分散計算における検証の量子版などの対話型証明の新しい側面について研究を進めるとともに,そこから派生する量子計算量理論,量子アルゴリズム,量子情報理論の研究を推進していく予定である.
