    • Symmetry between the parties is typically required by quantum protocols and should be fulfilled by experimental realizations; hence we do not consider here nonsymmetric states where a different number of photons is subtracted from each beam. However, since these instances can more closely resemble realistic implementations, we commit ourselves to extend our methods to encompass such a more general framework in further work.

    • The rigorous validity of this lower bound relies on the widespread conjecture on the additivity of EF, which holds true for Gaussian states, but no proof is known for PSS.
