Abstract: Disclosed is a multi-constraint qubit allocation method and a quantum apparatus using the same. The method comprises generating an interaction graph representing a quantum circuit on the basis of the number of two-qubit gates, determining edge weights between connected nodes in the interaction graph by introducing a fitting coefficient for a decay effect, searching for an isomorphic part, layout graph, between target hardware and the interaction graph by graph matching, and performing frequency matching for a layout graph by searching for frequency allocated to each location of qubits by limiting unidirectional movement on each of an x-axis and a y-axis of a hardware plane of the target hardware to a range from −1 to +1.

Abstract: The present disclosure relates to a transition metal-doped nickel phosphide nanostructure, a method for preparing the same, and a catalyst for electrochemical water decomposition including the transition metal-doped nickel phosphide nanostructure. More specifically, a transition metal-doped nickel phosphide nanostructure can be prepared by converting a zinc oxide nanostructure grown on a substrate vertically by hydrothermal synthesis to a transition metal-doped nickel oxide nanostructure by cation exchange and then phosphorizing the nickel oxide. The transition metal-doped nickel phosphide nanostructure of the present disclosure is advantageous in that it has superior catalytic activity and conductivity due to large surface area. In addition, when used as a catalyst for water decomposition under an alkaline condition, it has a low overvoltage and can have excellent catalytic activity for hydrogen evolution reaction or oxygen evolution reaction.

Abstract: A method of manufacturing a meta-optical element includes propagating light with random phase distribution toward a light collecting surface, obtaining a simulation intensity of the light at the light collecting surface through simulation, generating an error function based on an error data which is a difference between the simulation intensity of the light and an ideal intensity of the light, obtaining an optimal phase distribution of the light which outputs a minimum function value of the error function by applying a gradient descent, and forming a meta-optical element that implements the optimal phase distribution.
