METHODS AND ARRANGEMENTS FOR OPTIMALLY DESIGNING COMPLEX RESONATOR NETWORK

Abstract: for producing a quantum microwave circuit, a network model is provided. each resonator element therein is characterised by one or more respective physical quantities that define a contribution of the respective resonator element to one or more resonator modes of the microwave circuit. values of respective parameters (x) constitute a vector (1), an initial form of which is (2). a characteristic of said microwave circuit at the t: th resonator mode as a quantity dependent on a complex number st having a real part and an imaginary part. the real part is defined in relation to a target decay constant and the imaginary part is defined in relation to a target resonance frequency of the respective resonator mode. beginning from said initial form (2), a numerical optimization method finds the vector (1) that gives an extreme value of an objective function dependent on said quantity. a physical instance of said microwave circuit is manufactured with the respective physical quantities having said found values of the parameters (x).
