Comment on "Multivariable quantum signal processing (M-QSP): prophecies of the two-headed oracle"

Multivariable Quantum Signal Processing (M-QSP) \cite{Rossi2022multivariable} is expected to provide an efficient means to handle polynomial transformations of multiple variables simultaneously. However, we identified several inconsistencies in the main theorem, where necessary and sufficient condit...
