In Griffith books of introduction to QM, it say that Quantum State, mathematically represented as a vector.(adsbygoogle = window.adsbygoogle || []).push({});

My problem is with understanding what are thecomponentsof such a vector. Do I understand it correctly, that, say, in case of a particle in a box, Quantum State, as a vector is a superposition of all singular possible in particle in a box wave functions which constitute a components of a quantum state vector?

If so, then, if Quantum State is purely a wave function corresponding to second energy level say, then the Quantum State vector will be

{0, sqrt(2/a), 0, 0, ... 0}

or vector component can be either only either 1 or 0? Or value of a component is a Fourier coefficient?

* "a" is a width of a potential well

Thank you.
