1.2.3 The Bloch sphere representation of the density matrix
There exists a great way to visualize a single qubit using the Bloch sphere representation. If you’ve never heard about this concept, we recommend that you first check out module 0 where we introduce the Bloch sphere for the first time.
Here, we will focus on the Bloch sphere representation in terms of the density matrix formalism. Let’s get started!
