Hi,

is there a simple way to apply a function (for example a sine or cosine) to a hermitian operator?

They are built in methods in qutip 4, Q.sinm and Q.cosm

Or, you can do it yourself using Q.expm

Hi Paul,

thanks a lot for your answer! Wait, is there a version 4 of qutip?? I tried to google it but I didn't find anything...

The expm should work fine for me, anyway! thanks!
