Hi all. I'm having a little trouble in understanding precisely how to calculate reduced density matrices. No literature I've been able to get my hands on has made it clear how precisely to work out partial matrices.
For example, if we have a bi-partite state for Alice's and Bob's particles...
Hey guys, I need some help understanding some very basic quantum manipulation techniques.
If I am working out the bra version of a tensor product on some ket vectors, do the two ket vectors change from |v1>|v2> to <v1|<v2|, or to <v2|<v1|.
Or, to put in context, if I measure an operator...
