Comment on “Consistent Quantization of Nearly Singular Superconducting Circuits”
I. L. Egusquiza, A. Parra-Rodriguez
The analysis conducted by Rymarz and DiVincenzo (Phys. Rev. X 13, 021017 (2023)) regarding quantization of superconducting circuits is insufficient to justify their general conclusions, most importantly the need to discard Kirchhoff's laws to effect variable reductions. Amongst a variety of reasons, one source of several disagreements with experimental and theoretical results is the long-standing dispute between extended vs compact variables in the presence of Josephson junctions.
