In other words, the vectors calculated after finding a linear dependent vector can be assumed to be zeros. different spaces. For example, in tr[(A⊗1)ρ] the trace is taken over H 1 ⊗H 2, whilst in tr[Aρ 1] it goes only over H 1. It is for this reason that ρ 1 and ρ 2 are called partial traces of ρ, because, in passing from tr[(A⊗1)ρ] to tr[Aρ 1] the trace over H 2 has already been carried out.
