1 Vector spaces and dimensionality

But finding a complex unitary C is not so easy when Z and S are complex; a nonzero column v satisfying v HSv = 0 generally requires three nonzero elements. In this complex case a simpler way to find C may be the Jacobi-like iteration described on p. 77 of R.A. Horn and C.R.

I'm having trouble fully wrapping my head around unitary matrices. I'm working on them in relation to quantum mechanics. The question specifically I am working on is: Given the Pauli matrices $\
