Is the following a theorem? yes or no(adsbygoogle = window.adsbygoogle || []).push({});

If A and B are non-commuting Hermitian operators (or matrices), there does not exist Hermitian operators C and D such that AB-BA = CD.

(Or, as special case, ....there does not exist a Hermitian operator C s.t. C= AB-BA)

Thanks
