Quantum polarisation probability

  1. Jun 11, 2017 #1
    1. The problem statement, all variables and given/known data
    upload_2017-6-11_11-56-49.png
    I am stuck on the second paragraph but I thought I would add the first paragraph in case some context would help!
    2. Relevant equations
    |A> = cos(theta)|H> + sin(theta)|V>

    3. The attempt at a solution

    I am not wholly comfortable with bra-ket notation with the outer product

    p = <A|thetaA><thetaB|B> [maybe not sure]

    not sure what to do from here..

    thank you for any help upload_2017-6-11_11-56-49.png upload_2017-6-11_11-56-49.png upload_2017-6-11_11-56-49.png upload_2017-6-11_11-56-49.png
