  46. Equivalence of Non-Perfect Secret Sharing and Symmetric Private Information Retrieval With General Access Structure Reviewed International coauthorship International journal

    We study the equivalence between non-perfect secret sharing (NSS) and symmetric private information retrieval (SPIR) with arbitrary response and collusion patterns. NSS and SPIR are defined with an access structure, which corresponds to the authorized/forbidden sets for NSS and the response/collusion patterns for SPIR. We prove the equivalence between NSS and SPIR in the following two senses. 1) Given any SPIR protocol with an access structure, an NSS protocol is constructed with the same access structure and the same rate. 2) Given any linear NSS protocol with an access structure, a linear SPIR protocol is constructed with the same access structure and the same rate. We prove the first relation even if the SPIR protocol has imperfect correctness and secrecy. From the first relation, we derive an upper bound of the SPIR capacity for arbitrary response and collusion patterns. For the special case of \mathsf {n} -server SPIR with \mathsf {r} responsive and \mathsf {t} colluding servers, this upper bound proves that the SPIR capacity is (\mathsf {r}-\mathsf {t})/\mathsf {n}. From the second relation, we prove that a SPIR protocol exists for any response and collusion patterns.

  47. On the Capacity of Quantum Private Information Retrieval From MDS-Coded and Colluding Servers Reviewed International coauthorship

    In quantum private information retrieval (QPIR), a user retrieves a classical file from multiple servers by downloading quantum systems without revealing the identity of the file. The QPIR capacity is the maximal achievable ratio of the retrieved file size to the total download size. In this paper, the capacity of QPIR from MDS-coded and colluding servers is studied for the first time. Two general classes of QPIR, called stabilizer QPIR and dimension-squared QPIR induced from classical strongly linear PIR are defined, and the related QPIR capacities are derived. For the non-colluding case, the general QPIR capacity is derived when the number of files goes to infinity. A general statement on the converse bound for QPIR with coded and colluding servers is derived showing that the capacities of stabilizer QPIR and dimension-squared QPIR induced from any class of PIR are upper bounded by twice the classical capacity of the respective PIR class. The proposed capacity-achieving scheme combines the star-product scheme by Freij-Hollanti et al. and the stabilizer QPIR scheme by Song et al. by employing (weakly) self-dual Reed-Solomon codes.

    As a modern approach for the foundation of quantum theory, existing studies of general probabilistic theories gave various models of states and measurements that are quite different from quantum theory. In this Letter, to seek a more realistic situation, we investigate models approximately close to quantum theory. We define larger measurement classes that are smoothly connected with the class of POVMs via a parameter, and investigate the performance of perfect discrimination. As a result, we give a sufficient condition of perfect discrimination, which shows a significant improvement beyond the class of POVMs.

    We discuss the effect of sequential error injection on information leakage under a network code. We formulate a network code for the single transmission setting and the multiple transmission setting. Under this formulation, we show that the eavesdropper cannot increase the power of eavesdropping by sequential error injection when the operations in the network are linear operations. We demonstrated the usefulness of this reduction theorem by applying a concrete example of network.

    In this work we study the problem of secure communication over a fully quantum Gel'fand-Pinsker channel. The best known achievability rate for this channel model in the classical case was proven by Goldfeld, Cuff and Permuter, and here we generalize their result. One key feature of the results obtained in this work is that all the bounds are based on error exponents. We obtain our achievability result via the technique of simultaneous pinching. This in turn allows us to show the existence of a simultaneous decoder. Further, to obtain our encoding technique and to prove the security feature of our coding scheme we prove a bivariate classical-quantum channel resolvability lemma and a conditional classical-quantum channel resolvability lemma. As a byproduct of the achievability result obtained in this work, we also obtain an achievable rate for a fully quantum Gel'fand-Pinsker channel in the absence of Eve. The form of this achievable rate matches with its classical counterpart. The Gel'fand-Pinsker channel model had earlier only been studied for the classical-quantum case and in the case where Alice (the sender) and Bob (the receiver) have shared entanglement between them.

    Quantum communication over network is particularly appealing in a similar way to classical network communication, but a partially corrupted quantum network has not been sufficiently studied. We discuss quantum state transmission over a partially corrupted quantum network, in which the sender transmits m0 qudits, i.e., d-level systems, to the receiver via network, but m1 channels are corrupted. As our result, we show that the optimal transmission rate is at least (m0-2m1+1)logd under the following two settings. In the first case, the unitaries on intermediate nodes are arbitrary and the corruptions on the m1 channels are individual. In the second case, the unitaries on intermediate nodes are restricted to Clifford operations and the corruptions on the m1 channels are adaptive, i.e., they are caused by an attack with a quantum memory. Further, our code in the second case realizes the noiseless communication even with the single-shot setting and is constructed dependently only on the network topology and the places of the m1 corrupted channels.

    Compute-and-forward (CAF) relaying is an effective way to increase bandwidth efficiency of wireless two-way relay channels. Design of error-correcting codes and their decoding algorithms suitable for CAF relaying schemes remains an important issue to be studied. In this paper, we will analyze an asymptotic behavior of LDPC codes over two-way relay channels based on density evolution (DE). Because of the asymmetric characteristics of the channel, we use the population dynamics DE combined with DE formulas for asymmetric channels to obtain the belief propagation (BP) thresholds. Additionally, we also evaluate the asymptotic performance of spatially coupled LDPC codes for two-way relay channels. The results indicate that the spatially coupled codes yield improvements in the BP threshold compared with corresponding uncoupled codes for two-way relay channels.

    Quantum private information retrieval (QPIR) is a protocol that a user retrieves one of f files from non-communicating n servers by downloading quantum systems without revealing the identity of the target file. As variants of the QPIR with stronger security requirements, the symmetric QPIR is that the files except for the target file are not leaked to the user, and the t-private QPIR is that the identity of the target file is kept secret even if at most t servers may collude to reveal the identity. The QPIR capacity is the maximum ratio of the one file size to the size of downloaded quantum systems, and we prove that the symmetric t-private QPIR capacity is min {1, 2(n - t)/n} for any 1 ≤ t < n. We construct a capacity-achieving QPIR protocol by the stabilizer formalism and prove the optimality of our protocol. The proposed capacity is greater than the classical counterpart.

    We give a capacity formula for the classical communication over a noisy quantum channel, when local operations and global permutations allowed in the encoding and bipartite states preshared between the sender and the receiver. The two endpoints of this formula are the Holevo capacity (without entanglement assistance) and the entanglement assisted capacity (with unlimited entanglement assistance). What's more, we show that the capacity satisfies the strong converse property and thus the formula serves as a sharp dividing line between achievable and unachievable rates of communication. We prove that the difference between the assisted capacity and the Holevo capacity is upper bounded by the discord of formation of the preshared state. As examples, we derive analytically the classical capacity of various quantum channels of interests. Our result witnesses the power of random permutation in classical communication, whenever entanglement assistance is available.

    Differential privacy (DP) is an influential privacy measure and has been studied to protect private data. DP has been often studied in classical probability theory, but few researchers studied quantum versions of DP. In this paper, we consider classical-quantum DP mechanisms which (i) convert binary private data to quantum states and (ii) satisfy a quantum version of the DP constraint. The class of classical-quantum DP mechanisms contains classical DP mechanisms. As a main result, we show that some classical DP mechanism optimizes any information quantity satisfying the information processing inequality. Therefore, the performance of classical DP mechanisms attains that of classical-quantum DP mechanisms.

    We address asymptotic decoupling in the context of Markovian quantum dynamics. Asymptotic decoupling is an asymptotic property on a bipartite quantum system, and asserts that any correlation between two quantum systems is broken after a sufficiently long time passes. In this paper, we show that asymptotic decoupling is equivalent to local mixing which asserts the convergence to a unique stationary state on at least one quantum system. If dynamics is asymptotically decoupling, any correlation between two quantum systems is broken exponentially. Also, we give a criterion of mixing that is a system of linear equations. All results in this paper are proved in the framework of general probabilistic theories, but we also summarize them in quantum theory.

    In this paper we propose a two-way protocol of physical layer security using the method of privacy amplification against eavesdroppers. First we justify our proposed protocol by analyzing the physical layer security provided by the classic wiretap channel model (i.e. one-way protocol). In the Gaussian channels, the classic one-way protocol requires Eve's channel to be degraded w.r.t. Bob's channel. However, this channel degradation condition depends on Eve's location and whether Eve's receiving antenna is more powerful than Bob's. To overcome this limitation, we introduce a two-way protocol inspired in IEEE TIT (1993) that eliminates the channel degradation condition. In the proposed two-way protocol, on a first phase, via Gaussian channel, Bob sends randomness to Alice, which is partially leaked to Eve. Then, on a second phase, Alice transmits information to Bob over a public noiseless channel. We derive the secrecy capacity of the two-way protocol when the channel to Eve is also Gaussian. We show that the capacity of the two-way protocol is always positive. We present numerical values of the capacities illustrating the gains obtained by our proposed protocol. We apply our result to simple yet realistic models of satellite communication channels.

    We derive finite-length bounds for two problems with Markov chains: source coding with side-information where the source and side-information are a joint Markov chain and channel coding for channels with Markovian conditional additive noise. For this purpose, we point out two important aspects of finite-length analysis that must be argued when finite-length bounds are proposed. The first is the asymptotic tightness, and the other is the efficient computability of the bound. Then, we derive finite-length upper and lower bounds for the coding length in both settings such that their computational complexity is low. We argue the first of the above-mentioned aspects by deriving the large deviation bounds, the moderate deviation bounds, and second-order bounds for these two topics and show that these finite-length bounds achieve the asymptotic optimality in these senses. Several kinds of information measures for transition matrices are introduced for the purpose of this discussion.

    <p>Coding technology is used in several information processing tasks. In particular, when noise during transmission disturbs communications, coding technology is employed to protect the information. However, there are two types of coding technology: coding in classical information theory and coding in quantum information theory. Although the physical media used to transmit information ultimately obey quantum mechanics, we need to choose the type of coding depending on the kind of information device, classical or quantum, that is being used. In both branches of information theory, there are many elegant theoretical results under the ideal assumption that an infinitely large system is available. In a realistic situation, we need to account for finite size effects. The present paper reviews finite size effects in classical and quantum information theory with respect to various topics, including applied aspects.</p>

    We explain second-order asymptotic theory via the information spectrum method. From a unified viewpoint based on the generality of the information spectrum method, we consider second-order asymptotic theory for use in fixed-length data compression, uniform random number generation, and channel coding. Additionally, we discuss its application to quantum cryptography, folklore in source coding, and security analysis.

    位相推定問題についての多くの研究ではNoon 状態を入力状態として用いる方法が提案されている.理由はNoon 状態を入力状態とした場合,ある点でFisher 情報量が最大となるからである.しかし,Fisher 情報量が必ずしも達成可能な推定誤差を与えるとは限らない.本稿では,Mini-max 基準に加え,局所漸近Mini-max 基準を考え,これらの場合に,Fisher 情報量が達成可能な推定誤差を与えないことを示す.さらに,Noon 状態に代わり,漸近的に最適な入力状態を光子数に関する制約条件の下で与える.

    In this paper, we introduce the concept of dual universality of hash functions and present its applications to various quantum and classical communication models including cryptography. We begin by establishing the one-to-one correspondence between a linear function family F and a code family C, and thereby defining ε-almost dual universal_2 hash functions, as a generalization of the conventional universal_2 hash functions. Then we give a security proof for the Bennett-Brassard 1984 protocol, where the Shor-Preskill-type argument is used, but nevertheless ε-almost dual universal_2 functions can be used for privacy amplification.

    We derive a new upper bound for Eve's information in secret key generation from a common random number without communication. This bound improves on Bennett's bound based on the Renyi entropy of order 2 because the bound obtained here uses the Renyi entropy of order 1+s for s∈[0,1]. This bound is applied to a wire-tap channel. Then, we derive an exponential upper bound for Eve's information. Our exponent is compared with Hayashi's exponent. For the additive case, the bound obtained here is better. The result is applied to secret key agreement by public discussion.

    1999年にAmbainis, Nayak, Ta-shma, Vaziraniによって導入された(n,1,p)-量子ランダムアクセス符号とは,次のような通信システムである.nビットの情報を持つ送信者はその情報を1キュビットに符号化してそれを受信者に送る.受信者は正作用素値測度によって定義される量子的復号プロセスによりp以上の確率で正しく元のnビットの任意の1ビットを復号することができる.Ambainisらは(2,1,0.85)-量子ランダムアクセス符号の存在を示し,同時に古典的にはそのような符号は不可能であることを示した.ChaungはAmbainisらの符号を(3,1,0.79)-量子ランダムアクセス符号に拡張したが,それ以来p>1/2をみたす(4,1,p)-量子ランダムアクセス符号の存在は未解決であった.この論文ではこの未解決問題に対する否定的回答を与える.

    Concerning the estimation problem of the eigen-value of the density in the quantum two-level system, I compare the accuracy of a estimator based on a quantum measurement with quantum correlation in measuring apparatus with that of the optimal estimator based on a measurement without quantum correlation. It is proven that the estimator realized by Hendrych, et al. (2003) is better than the optimal case without quantum correlation when the true state is closed to a pure state. Although Hendrych, et al. did not discuss the accuracy of their estimation sufficiently, it is expected to be able to be realized to perform an estimation whose accuracy is better than the optimal case without quantum correlation.

    本発表では確率分布Pから生成されるの独立同一乱数を、Qから生成される独立同一乱数へ変換する際の最適生成レートに関して論じる。確率分布QまたはPが一様分布である場合は、この問題はそれぞれintrinsic randomnessおよびresolvabilityと呼ばれており、一次だけでなく二次の漸近解析もなされてきた。一方、PおよびQの双方が非一様分布である場合、その二次漸近論は扱われてこなかった。本発表ではPおよびQが有限集合上の一様とは限らない確率分布とし、それらの間の最適変換レートを行う。We treat a random number generation from an i.i.d. probability distribution of P to that of Q. When Q or P is a uniform distribution, the problems have been well-known as the uniform random number generation and the resolvability problem respectively, and analyzed not only in the context of the first order asymptotic theory but also that in the second asymptotic theory. On the other hand, when both P and Q are not a uniform distribution, the second order asymptotics has not been treated. In this paper, we focus on the second order asymptotics of a random number generation for arbitrary probability distributions P and Q on a finite set. In particular, we derive the optimal second order generation rate under an arbitrary permissible confidence coefficient.

    Hidden Markovian process is composed of visible and hidden variables, and only visible variables can be observed. This study focused on the k-order transition matrix on visible variables, and derived the method to estimate the transition matrix on visible and hidden variables from the k-order transition matrix on visible variables. In this method, we applied em-algorithm with respect to the geometrical structure over the space composed of k-order transition matrix on visible and hidden variables. Then, we clarified the asymptotic behavior of the error of the proposed method. Further, we studied the equivalence problem at the level of the tangent space. That is, we derived the necessary and sufficient condition for the equivalence in the tangent space.

    Here, we studied a secret communication on a quantum network. We especially focused on using network coding for improving security on quantum networks in order to complement a quantum key distribution (QKD) among nodes. As a result, we derive a sufficient condition for a quantum multiple-unicast network code to have a secrecy for Eve’s attack on a set of edges. Further, we develop a method for improving a security for Byzantine attacks on a relay scheme of keys generated by QKD by using classical network coding.

    In this study, based on the obtained result for a multi-user type quantum network, I studied a method for quantum computation with self-verification. For this aim, I focused on measurement-based quantum computation, which is composed of local measurement and a large entangled state, e.g., a graph state and a hypergraph state. Hence, I studied verification of pure states including graph states and hypergraph states under various formulations. Especially, for self precision-guaranteed quantum computation, I proposed a method for self-verification for triangle cluster state, which is a typical example of a graph state. Based on this method, I proposed a self precision-guaranteed method for quantum computation.

    A new algorithm by means only of four arithmetic operations among integers was proposed and implemented for solving partial differential equations, which are very important in physics, engineering and economics, with a very high accuracy. This is an extension of a similar integer-type algorithm for ordinary differential equations already proposed by the same principal investigator, by means of some ideas based on discrete mathematics.
    Though the implementation has not perfectly been completed, several mathematically interesting facts and new prospects were found about this algorithm. For example, it turned out that this numerical algorithm in the field of analysis (differentiation, integration etc) is closely related to the classical number theory.

    We have studied quantum communication technology on a multi-user network. Especially, we have studied the information theoretic security based on quantum communication technology because its realization is not easy for existing communication technology. The information theoretic security is usually realized by privacy amplification based on a code. We have clarified the effect by the finiteness of the length of the code while it had not been studied sufficiently. Further, we have investigated the blind computation based on quantum communication, which enables the client to ask the server the difficult computation without informing the server the knowledge of the request, whose security can be guaranteed information theoretically. We have derived the formula for guaranteeing the correctness of the computation result with a given significance level.

    In order to treat quantum advantage of multi-terminal quantum network, it is essential to use the quantum entanglement state among multi-terminal. In this research, I treated the distinguishability, the quantification, the classification, and the convertability for the quantum entanglement state among multi-terminal. Further, I showed the existence of the universal coding for quantum channel that well works for the one-input and multi-output case.

    Our topic is quantum statistical inference, which is statistical inference of quantum mechanical systems. We focused on statistical inference of correlated quantum systems and quantum channels, which are relatively new area. We successfully showed optimal measurements in variety of cases, and built some general theory. Also, we studied various properties of quantum correlation and quantum channels, and deepened the fundamental of quantum statistical inference.

    The statistical investigation on various themes was done as follows. (1) Involving a relationship between statistical models and statistics, the properties of the models were discussed and some interesting results on the behavior of various statistics are obtained. (2) In the theory of statistics to finance, time series and their applications, statistical procedures were shown to be asymptotically useful. (3) In the experimental design and its related area, the mathematical structure is clarified by combinatorial procedures, and results intended to apply to practical problems were obtained. (4) In statistical sequential inference, some sequential procedures were proposed, and their properties were discussed in details. The asymptotic efficiencies were shown. (5) The construction of mathematically fundamental theory of biostatistics is tried, and statistically inferential procedures are shown to play an important role. In particular, bioassay test, score test etc. were shown to be useful. (6) The relationship between non-locality in quantum mechanics and statistical inference is clarified, and inferential procedures is also shown to be efficient in quantum estimation and quantum test. Further, it is recognized to play an important role as the theoretical base of concrete physical phenomena. (7) In statistical inference, on the lower bound for tail probabilites of consistent estimators, the first and second order asymptotic efficiencies are investigated from a different viewpoint from conventional Bahadur efficiency. And in order to unify both of non-parametric and parametric tests, the mathematical setup was done, new test statistics based on estimators of spectral density matrics were proposed, and their asymptotic properties are derived. (8) Under a family of non-parametric quantum states, state estimation, prediction of quantum state, quantum information geometry and discrimination problem on quantum states are trated, and new interesting results were obtained. Many symposium on the above were held and active discussion and mutual exchange of information were also done. Their results were summarized as a volume.
