thanks so much to share this playlist 🤓
4:46 Why is the classical field amplitude only replaced by the annihilation operator a, why not with the full electric field quantised operator in terms of (a + a^\dagger)?
I think that is because we have E^(+) and not E. E = E^(+) + E^(-) and E^(+)∝â
@@κπυα what is the meaning of E+? The em field incident on the beam splitter should be E, isn't it?
