Hi guys having a little trouble with two-qubit state multiplication.(adsbygoogle = window.adsbygoogle || []).push({});

Could you tell me how you work out the following? (not only the answers but the working out) I need to be able to understand these calculations before I can move on to the next step of an entanglement question. I understand single qubit bra and ket notation for example |0><0|. And I know |00> means the tensor product of |0> and |0> but I am struggling to compute the following:

|00><00| = ?

|00><01| = ?

|00><10| = ?

|00><11| = ?

|01><00| = ?

|01><01| = ?

|01><10| = ?

|01><11| = ?

|10><00| = ?

|10><01| = ?

|10><10| = ?

|10><11| = ?

|11><00| = ?

|11><01| = ?

|11><10| = ?

|11><11| = ?

Thanks in advance. (ps i hope i posted this in the right place, please move it if not)
