  • Publication number: 20240080185
    Abstract: A result confirmation unit (204) computes a state space probability that is a probability that a verification target device (300) has not correctly prepared a state space having a quantum state stored therein, a Pauli measurement probability that is a probability that the verification target device (300) has not correctly performed Pauli Z measurement and Pauli X measurement, and a magic state probability that is a probability that the verification target device (300) has not generated a magic state of CCZ. Then, using the state space probability, the Pauli measurement probability, and the magic state probability, the result confirmation unit (204) computes a degree of approximation between a quantum state and the magic state of CCZ at the verification target device (300) and measurement accuracies of the Pauli Z measurement and the Pauli X measurement on the quantum state at the verification target device (300).

  • Publication number: 20220185677
    Abstract: Hafnium carbide powder for plasma electrodes is represented by a chemical formula HfCx (where x=0.5 to 1.0). The content of carbon particles contained as impurities in the hafnium carbide powder is less than or equal to 0.03% by mass. The hafnium carbide powder preferably has an average particle size of 0.5 to 2 ?m. To produce the hafnium carbide powder, a pellet made from mixed powder of hafnium oxide and carbon is first placed in a second crucible made of silicon carbide. Then, the hafnium carbide powder is formed by heating the second crucible at 1800 to 2000° C. with the second crucible arranged in a first crucible made of carbon.

  • Publication number: 20180354171
    Abstract: A production method for a cover attached to an outer ring of a hub unit including procedures as follows. A nut is supported by a first protrusion of a first mold. By a second protrusion of a second mold, a core bar including a cylindrical section to be inserted into the outer ring is supported. A resin material is injected into a cavity formed by the first mold and the second mold to form a cover including a nut and a core bar. The cover is detached from the second mold by moving the first mold in a direction of being separated from the second mold. After this, the cover is detached from the first mold by pushing out the cover in a die matching direction with a pin disposed in the first mold.

  • Publication number: 20180345550
    Abstract: A production method for a cover attached to an outer ring of a hub unit first prepares a first mold and a second mold which form a cavity filled with a resin material. Next, by a protrusion of the first mold, a nut is supported. Next, when viewed from an axial direction of the nut, in a state where at least a part of the gate of the second mold overlaps an inside of the nut as compared with an outer circumferential surface of the nut, the first mold and the second mold are die-matched. Then, a resin material is injected into the cavity.
