Quantum computational universality of hypergraph states with Pauli-X and Z basis measurements

Measurement-based quantum computing is one of the most promising quantum computing models. Although various universal resource states have been proposed so far, it was open whether only two Pauli bases are enough for both of universal measurement-based quantum computing and its verification. In this paper, we construct a universal hypergraph state that only requires $X$ and $Z$-basis measurements for universal measurement-based quantum computing. We also show that universal measurement-based quantum computing on our hypergraph state can be verified in polynomial time using only $X$ and $Z$-basis measurements. Furthermore, in order to demonstrate an advantage of our hypergraph state, we construct a verifiable blind quantum computing protocol that requires only $X$ and $Z$-basis measurements for the client.Comment: 12 pages, 8 figures, 1 table, close to published versio

Application of CFD analysis for static and dynamic characteristics of hydrodynamic journal bearing

International audienceJournal bearings are one of the most important mechanical elements for the stable operation of rotors. Rotational machinery is becoming larger and more complicated in recent years, so proper design of bearings is necessary to offer stable support. However, bearings with shapes and operating conditions that can not be predicted by the conventional Reynolds equation method exist. In this paper ,therefore, a prediction method of vibration characteristics of journal bearings using CFD was constructed. To calculate the dynamic characteristics, mesh morphing methods simulating two oscillating states were studied. In order to compare with the calculation results, an active oscillating rotor using magnetic bearings was constructed. As a result, the calculation results were roughly consistent with the experimental results, and a prediction method by CFD was constructed

Review of Big Five research from developmental perspective

The theory of Big Five is an effective model, in which the personality structure is described in terms of extraversion, agreeableness, conscientiousness, emotional stability, intellect. Big Five was originally developed as a tool for the personality description of adults, but has proved effective also for developmental research. From childhood through adolescence and adulthood, many questionaaire studies revealed the 5 factor personality structure. On the other hand A individual difference in infancy and early childhood is studied in terms of ""temperament."" The relation between Big Five and temperament in not clear. Hogekull(1994) presented a hypothetical relation between Big Five and temperament, and assumed that Big Five develops from the temperament dimensions of Emotionality, Activitity, Sociability, Impulsivity, Shyness of EASI, which appear to be related with Intensity/Activity, Approach-Withdrawal, Attentiveness, Manageability of TBQ
