I have been using incorrect terminology for this concept, so I wanted to use correct terminology if it exists. Like I would rather not say "set" if I could say "magma" in abstract algebra. But it sounds like it doesn't. To distinguish a quantum field and a quantum field theory in your answer was already very helpful though. | |

| Jul 29, 2018 at 11:35 | comment | added | David Bar Moshe | you mean a projective Hilbert space? | |
| Jul 29, 2018 at 11:27 | comment | added | user183966 | Thank you for trying to help me. I think this has made the terminology clearer, I have updated the question title to hopefully be more accurate. So when we say "field" we mean a value, like position, a "quantum field" is an operator/collection of operators, like like the position operator. So my question would be whether there is a standard name for a Hilbert space that has an interpretation as a state space for a quantum field. ie. a term that includes the Hilbert spaces of the electron quantum field theory, the photon quantum field theory, a scalar quantum field theory, etc. | |
