Rotation around a generic axis
In the previous post, we saw how to rotate the density operator with respect to the x, y, and z axes, and we derived simple formulas...

Pauli Algebra and Rotations on the Bloch sphere
In this post, we explore a topic already discussed in the previous post: the representation of the density operator on the Bloch sphere....

The Bloch Sphere (part 2: Visualise the Quantum States)
By the end of this post, you'll be able to visualise quantum states on a sphere. We'll write a very small script that will also allow you...
