Quantum Gates as Matrices
The go-to visual for orthogonal vectors is unit
lengths directed along the coordinate axes.
This picture, though appealing, quickly breaks down.
With two qubits, we’ll have vectors with
22 or 4 elements, making
them hard to visualize in 3D space.
As explained in From Sphere to Hemisphere: The True Space,
in the weird geometry of quantum mechanics, the vector
for 
points upward while
that for 
is
downward and not perpendicular to the vector for
.
When quantum computers become practical to unleash on large scale problems, ...
