Ket Vectors

  1. Nov 5, 2015 #1
    I'm attempting to learn the mathematics of quantum mechanics using textbooks such as "The Principles of Quantum Mechanics" by Dirac. I'm uncertain however of how ket vectors work! Say |A> + |B> = |C>, then what does |C> please represent?

    If you are not familiar with the mathematical concept of a "vector space", you'll want to check that out.

    Dirac is not easy to learn from. Try Ballentine.

    If |A> and |B> denote possible states of a system, then the sum denotes another possible state of that system.

    I totally concur.

    I actually learnt it from Dirac and Von Neumann. I wish I didn't. It would be much better to start with Ballentine then read those two seminal texts.

    I get the feeling though your math may not be up to Ballentine. In that case I suggest you work your way up in the following order:
    https://www.amazon.com/Quantum-Mechanics-The-Theoretical-Minimum/dp/0465062903
    https://www.amazon.com/Quantum-Mechanics-Demystified-2nd-Edition/dp/0071765638
    https://www.amazon.com/Principles-Q...46157675X/ref=mt_paperback?_encoding=UTF8&me=

    Then you can tackle Ballentine.

    It may seem like a lot of work but remember its not a race. Take your time and cement your understanding.

    Thanks
