Question related to functional analysis












1














I am interested in studying functional analysis and I am wondering what sort of practical applications the field has and what, if any, career paths might require functional analysis. Thank you!

          Welcome to MSE! Hilbert spaces are a vital part of functional analysis which in turn are the basis of quantum mechanics and quantum computing.

            Wouldn't finite dimensional Hilbert spaces be enough for quantum computing, since you only have a finite number of qbits? Then you could argue whether functional analysis is necessary for this case.

          • Right. At least you have unitary transformations.
