       Unitaries generated by polynomials of position and momentum can exactly realize any finite-dimensional unitary evolution, and any physical bosonic unitary evolution can be approximated by a finite-dimensional unitary evolution \cite{arxiv:2110.06942,arxiv:2501.13857,arxiv:2510.08546}. 
       Certain non-quadratic Hamiltonians yield infinite-energy states in finite time \cite{arxiv:2510.08545}.
       See Ref. \cite{arxiv:2410.04274} for bosonic computational complexity classes. 
-      The stellar rank quantifies the degree of non-Gaussianity of single-mode states \cite{arxiv:1907.11009}. 
+      The stellar rank \cite{arxiv:1907.11009} and symplectic rank \cite{arxiv:2504.19319} quantify the degree of non-Gaussianity of bosonic states. 
       Functional MPS can be used to simulate evolution of non-Gaussian states \cite{arxiv:2504.05860}.
       Universal bosonic quantum computations can be simulated in exponential time on a classical computer \cite{arxiv:2503.03600}.
