Does the basis with vectors called |+> and |-> represent a maximally non-orthogonal basis in relation to the computational basis with vectors called |0> and |1> (meaning that |+> and |-> are at 45 degrees in relation to 0> and | 1>)?
In quantum information science, the concept of bases plays a important role in understanding and manipulating quantum states. Bases are sets of vectors that can be used to represent any quantum state through a linear combination of these vectors. The computational basis, often denoted as |0⟩ and |1⟩, is one of the most fundamental bases
