[ameyer-rigetti]

Try them here (based on this branch): https://mybinder.org/v2/gh/rigetti/qiskit-rigetti/binder?filepath=examples

TODO:

• [x] After merging, go to https://mybinder.org and create an image for the main branch (starting in examples dir)

Note that the duplicate plots is a bug in qiskit's visualization extra. It even shows up in their own docs: https://qiskit.org/documentation/tutorials/circuits/2_plotting_data_in_qiskit.html
