1.2.3 The Bloch sphere representation of the density matrix

Course subject(s) 01. Quantum tools and a first protocol

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!

Sorry but there don't seem to be any downloads..
