 When studying the dynamics of a two-level system, it's often convenient to visualize the state of the system by plotting the state vector or density matrix on the Bloch sphere.
 
-In [QuantumToolbox.jl](https://qutip.org/QuantumToolbox.jl/), this can be done using the [`Bloch`](@ref) or [`plot_bloch`](@ref) methods that provide same syntax as [QuTiP](https://github.com/qutip/qutip).
