Abstract: The present invention relates to a quantum computing unit comprising a superconducting substrate or other superconducting component, at least three outer Majorana modes, and at least one inner Majorana mode, wherein the at least three outer Majorana modes are located along an outer perimeter, and wherein the at least one inner Majorana mode is located within the outer perimeter. This spatial configuration of the four participating Majorana modes allows to control the time-dependent coupling between the respective Majorana modes. The related quantum gates can be performed perfectly in a finite time, preferably with a frequency of up to several GHz. These include the braiding gate, the π/8 magic phase gate, the π/12 phase gate, and, for multi-qubit systems, the CNOT gate. The robustness of the mechanism guarantees that for special times the quantum gate is conducted the quantum gate is perfectly realized. This property is independent of material specific parameters. Hence, the behavior can be expected in all systems where Majorana zero modes appear in the center of Abrikosov vortices, in particular, not only in FeTeSe, which we consider as an example.

Abstract: The invention presents a method for predicting volatile organic compounds (VOCs) adsorption capacity via filling adsorption, in the domain of exhaust gas treatment. Utilizing two or more porous materials with concentrated pore size distributions as model adsorption materials, it identifies the critical pore size for filling adsorption under specific conditions. Filling adsorption operates via volume filling, linking adsorption capacity to density and pore volume. Conversely, non-filling adsorption relies on surface covering mechanisms, correlating adsorption capacity with specific surface area. By establishing a linear equation using pore volume and specific surface area, solved with known model material parameters, it accommodates pore size variation and pressure influence on adsorption capacity. This equation predicts VOCs adsorption capacity and isotherms based on the adsorption material's pore structure.

Abstract: A flexible intestinal anastomosis stent which sucks secretions on an inner wall of an intestinal tract and at a suture site into a horn-shaped channel through a through-hole. The secretion is discharged to an inside of the stent body through a liquid-inlet hole after being squeezed by intestinal tract contents, thereby reducing a risk of infection at the suture site. A lower edge of the outlet end of the stent body has a concave polygonal structure, each reflex angle at a lower edge of the concave polygonal structure being formed with one inwardly folded wrinkle structure on a side wall of the stent body, and the wrinkle structure also able to accommodate the secretions. The lower edge is stressed and deformed by the intestinal tract contents to reduce a reflex angle, so that secretions in the wrinkle structure are discharged downwardly, such that risk of complications is reduced.
