Hello everybody,
Dirac notation uses "bras"([itex] <a| [/itex]) and "kets"([itex] |b> [/itex]), which are row vectors and column vectors respectively, but what would something like [itex] |a, b> [/itex] mean? It makes no notational sense to me
Context: A couple of photons going through beam splitters in an interferometer. One is in state a and the other is in state b. If we had only 1 photon taking path a, and nothing in path b, then the notation becomes [itex] |a, 0> [/itex], but I don't know how to reconcile this with Dirac notation.
