Hi

I am a CS student trying to learn the basics of quantum physics. Sadly I can't even get pass the definition of Dirac notation because I do not know the meanings of some basic notations

The only thing I know is that V (superscript T) means transpose. Switch between column and row.

However, I keep seeing notations such as
V (superscript *)
V (superscript +) ==> [look more like a cross]

Can someone tell me that those mean? or maybe tell me what to read to learn about these basic notations?

Usually, V (superscript *) means complex conjugated matrix (i.e., all entries of V are complex conjugated) and V (superscript +) means Hermitean conjugated matrix (i.e., V is transposed and complex conjugated).

You should check the exact definitions in your textbook, because some authors use different notations.

thanks for your help

actually I was reading on my own. The book I picked didnt go over such minor detail.
 
Always use multiple sources when reading on your own.
