Abstract: The present disclosure provides a method and apparatus for adjusting a qubit frequency, an electronic device and a readable storage medium. For at least two frequency-adjustable qubits in a multi-bit quantum chip, a corresponding upper-limit/lower-limit setting parameter is determined through an upper-limit frequency and a lower-limit frequency centered by a target frequency and in combination with a fitting corresponding relationship, thus determining a rate between a change of a frequency and a change of a setting parameter. After the target setting parameter is set for each qubit, the parameter for another qubit directly coupled to the qubit is adjusted to the upper-limit setting parameter and the lower-limit setting parameter, and then the actual frequency of a current qubit is determined according to a current upper-limit frequency and a current lower-limit frequency.

Abstract: Provided is a method for catalytically reducing selenium. Hydrogen peroxide is used as a catalyst, and a reducer is added to a hexavalent-selenium-containing solution for reaction so as to reduce the selenium to elemental selenium, wherein the standard oxidation-reduction potential of the reducer is lower than the standard oxidation-reduction potential of the conversion of the hexavalent selenium to elemental selenium. The present method can further reduce a hexavalent-selenium element-containing selenic acid or selenate solution to an elemental selenium product in one step.
