scqubits.FullZeroPi.g_coupling_matrix#

FullZeroPi.g_coupling_matrix(zeropi_states=None, evals_count=None)[source]#

Returns a matrix of coupling strengths g_{ll’} [cmp. Dempster et al., text above Eq. (17)], using the states from ‘zeropi_states’. If zeropi_states==None, then a set of self.zeropi eigenstates is calculated. Only in that case is which used for the eigenstate number (and hence the coupling matrix size).

Return type:

ndarray

Parameters:

  • zeropi_states (ndarray | None) –

  • evals_count (int | None) –
