    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.

    The interplay between thermodynamics and information theory has a long history, but its quantitative manifestations are still being explored. We import tools from expected utility theory from economics into stochastic thermodynamics. We prove that, in a process obeying Crooks's fluctuation relations, every α Rényi divergence between the forward process and its reverse has the operational meaning of the "certainty equivalent"of dissipated work (or, more generally, of entropy production) for a player with risk aversion r=α-1. The two known cases α=1 and α=∞ are recovered and receive the new interpretation of being associated with a risk-neutral and an extreme risk-averse player, respectively. Among the new results, the condition for α=0 describes the behavior of a risk-seeking player willing to bet on the transient violations of the second law. Our approach further leads to a generalized Jarzynski equality, and generalizes to a broader class of statistical divergences.

  3. Unifying different notions of quantum incompatibility into a strict hierarchy of resource theories of communication Reviewed International coauthorship

    While there is general consensus on the definition of incompatible POVMs, moving up to the level of instruments one finds a much less clear situation, with mathematically different and logically independent definitions of incompatibility. Here we close this gap by introducing the notion of q-compatibility, which unifies different notions of POVMs, channels, and instruments incompatibility into one hierarchy of resource theories of communication between separated parties. The resource theories that we obtain are complete, in the sense that they contain complete families of free operations and monotones providing necessary and sufficient conditions for the existence of a transformation. Furthermore, our framework is fully operational, in the sense that free transformations are characterized explicitly, in terms of local operations aided by causally-constrained directed classical communication, and all monotones possess a game-theoretic interpretation making them experimentally measurable in principle. We are thus able to pinpoint exactly what each notion of incompatibility consists of, in terms of information-theoretic resources.

  4. Axioms for retrodiction: achieving time-reversal symmetry with a prior Reviewed

    We propose a category-theoretic definition of retrodiction and use it to exhibit a time-reversal symmetry for all quantum channels. We do this by introducing retrodiction families and functors, which capture many intuitive properties that retrodiction should satisfy and are general enough to encompass both classical and quantum theories alike. Classical Bayesian inversion and all rotated and averaged Petz recovery maps define retrodiction families in our sense. However, averaged rotated Petz recovery maps, including the universal recovery map of Junge–Renner–Sutter–Wilde–Winter, do not define retrodiction functors, since they fail to satisfy some compositionality properties. Among all the examples we found of retrodiction families, the original Petz recovery map is the only one that defines a retrodiction functor. In addition, retrodiction functors exhibit an inferential time-reversal symmetry consistent with the standard formulation of quantum theory. The existence of such a retrodiction functor seems to be in stark contrast to the many no-go results on time-reversal symmetry for quantum channels. One of the main reasons is because such works defined time-reversal symmetry on the category of quantum channels alone, whereas we define it on the category of quantum channels and quantum states. This fact further illustrates the importance of a prior in time-reversal symmetry.

    Observational entropy provides a general notion of quantum entropy that appropriately interpolates between Boltzmann’s and Gibbs’ entropies, and has recently been argued to provide a useful measure of out-of-equilibrium thermodynamic entropy. Here we study the mathematical properties of observational entropy from an information-theoretic viewpoint, making use of recently strengthened forms of the monotonicity property of quantum relative entropy. We present new bounds on observational entropy applying in general, as well as bounds and identities related to sequential and post-processed measurements. A central role in this work is played by what we call the ‘coarse-grained’ state, which emerges from the measurement’s statistics by Bayesian retrodiction, without presuming any knowledge about the ‘true’ underlying state being measured. The degree of distinguishability between such a coarse-grained state and the true (but generally unobservable) one is shown to provide upper and lower bounds on the difference between observational and von Neumann entropies.

    Von Neumann obtained the formula for the entropy of a quantum state by assuming the validity of the second law of thermodynamics in a thought experiment involving semipermeable membranes and an ideal gas of quantum-labeled particles. Despite being operational for the most part, von Neumann's argument departs from an operational narrative in its use of the spectral theorem. In this work, we show that the role of the spectral theorem in von Neumann's argument can be taken over by the operational assumptions of repeatability and reversibility, and, using these, we are able to explore the consequences of the second law also in theories that do not possess a unique spectral decomposition. As a byproduct, we obtain the Groenewold-Ozawa information gain as a natural monotone for a suitable ordering of instruments, providing it with an operational interpretation valid in quantum theory and beyond.

  9. Thermodynamic Constraints on Quantum Information Gain and Error Correction: A Triple Trade-Off Reviewed International coauthorship International journal

    Quantum error correction (QEC) is a procedure by which the quantum state of a system is protected against a known type of noise, by preemptively adding redundancy to that state. Such a procedure is commonly used in quantum computing when thermal noise is present. Interestingly, thermal noise has also been known to play a central role in quantum thermodynamics (QTD). This fact hints at the applicability of certain QTD statements in the QEC of thermal noise, which has been discussed previously in the context of Maxwell's demon. In this paper, we view QEC as a quantum heat engine with a feedback controller (i.e., a demon). We derive an upper bound on the measurement heat dissipated during the error-identification stage in terms of the Groenewold information gain, thereby also providing the latter with a physical meaning when it is negative. Further, we derive the second law of thermodynamics in the context of this QEC engine, operating with general quantum measurements. Finally, we show that, under a set of physically motivated assumptions, this leads to a fundamental triple-trade-off relation, which implies a trade-off between the maximum achievable fidelity of QEC and the super-Carnot efficiency that heat engines with feedback controllers have been known to possess. A similar trade-off relation occurs for the thermodynamic efficiency of the QEC engine and the efficacy of the quantum measurement used for error identification.

    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.
    今年度は,昨年度より研究を開始した量子対話型証明の一形態とみなせる量子分散検証について,ネットワーク上でのデータの等価性判定問題に関する効率的な量子プロトコルを構築することに成功した.この量子プロトコルは,古典の分散検証で必要とする証明の長さを指数的に改善している.本成果は,分散計算の国際会議DISCや量子情報科学のトップカンファレンスQIPで発表が採択され,国際的に高い評価を受けたと考えられる.また,量子計算の古典計算機による検証については,前年度に引き続き,合理的証明の概念を利用した対話プロトコルを構築した.古典の対話型証明で使用されるsumcheckベースの合理的対話プロトコルを与え,さらには合理的証明と従来の対話型証明の間にある種の条件が成り立つときの等価性を与えることができた.他にも,上記の研究から派生した成果として,量子アルゴリズムや量子情報理論に関する成果を得ることができた.量子アルゴリズムについては,最小スタイナー木問題に対して,現時点での最速な古典アルゴリズムよりも高速な量子アルゴリズムを新たに構築する一方で,行列の特異値分解に関連する幾つかの問題について,量子アルゴリズムの概念を利用することにより,高速な古典アルゴリズムを構築することができた.量子情報理論においては,リソース理論における空間的に分離された様々なリソースを包含および一般化するフレームワークと,それらの非古典性を定量化するためのツールを開発することができた.
    前年度に引き続いて,量子分散検証や合理的証明による量子計算の検証について研究を進展させることができただけでなく,量子アルゴリズムや量子情報理論についても著名な国際会議や学術雑誌で発表することができたことによる.
    引き続き,量子計算の検証や量子分散検証を始めとする対話型証明の新しい研究展開を推進していく予定である.また,そこから派生する研究分野として,量子通信を含む量子アルゴリズムや,量子通信計算量,量子情報理論の研究を推進して,量子対話型証明の理解に応用していく予定である.
