Supporting IonQ (or anything else than Rigetti)

[dexter2206]

For better research, we could think about using other quantum devices than the Rigetti one. However, there are several potential obstacles, outlined below, that could prevent us from doing so.

• [x] Check our AWS budget
• [x] Convince our supervisors that it is beneficial to use architectures other than Rigetti
• [x] Find out native gate sets for other architectures
• [x] Hand-compile circuits, provide API for choosing which "dialect" to use when constructing circuits
• [x] Provide the test script that verifies that hand-compiled circuits can indeed be run in verbatim mode on given devices
• [x] Run the script and fix possible incompatibilities

It seems that the only architectures that can run native circuits (i.e. use verbatim mode in Braket) are Rigetti QPUs and Lucy, see here. We know native getset for Rigetti, and according to the notebook linked above the native gate set for Lucy comprises following gates:

• ECR
• Identity
• RZ (with arbitrary angle)
• V (square root of X)
• X
