As in I have a basis set just like in the OP's case. Actually, I literally thought I should just form a N_A * N_B (being dimensions of the partitions) matrix out of coefficients of the state of the full system. Thank you for your comment and interest though. I am quite a beginner on the matter so pardon my ignorance. | |

You have to choose a partition of your system into two parts when you want to talk about entanglement. Which partition you choose is entirely up to you, but of course dictated by what entanglement you care about. | |
