We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

I also encountered this problem：

ImportError: cannot import name 'mrr_biphoton_wavefunction' from 'qinterconnect.solver' (C:\Program Files\Lumerical\v231\api\python\qinterconnect\solver.cp39-win_amd64.pyd)

But the version I am using is 2023 R1. And the case 'Spontaneous Parametric Down Conversion (SPDC) Photon Source' can operate normally.
