  • Publication number: 20230415350
    Abstract: An information processing device (10) includes: a first acquisition section (12) that acquires input data; a generation section that generates, from the input data, reservoir input data which is to be input to a quantum reservoir (20) having a plurality of layers of sub-reservoirs; a second acquisition section (12) that acquires an output result of the quantum reservoir to which the reservoir input data has been input; and an output data generation section (14) that generates output data with reference to the output result.

  • Patent number: 9455399
    Abstract: In a method of growing p-type nanowires, a nanowire growth solution of zinc nitrate (Zn(NO3)2), hexamethylenetetramine (HMTA) and polyethylenemine (800 Mw PEI) is prepared. A dopant solution to the growth solution, the dopant solution including an equal molar ration of sodium hydroxide (NaOH), glycolic acid (C2H4O3) and antimony acetate (Sb(CH3COO)3) in water is prepared. The dopant solution and the growth solution combine to generate a resulting solution that includes antimony to zinc in a ratio of between 0.2% molar to 2.0% molar, the resulting solution having a top surface. An ammonia solution is added to the resulting solution. A ZnO seed layer is applied to a substrate and the substrate is placed into the top surface of the resulting solution with the ZnO seed layer facing downwardly for a predetermined time until Sb-doped ZnO nanowires having a length of at least 5 ?m have grown from the ZnO seed layer.
