Firstly, apologies for the delay in responding here.
OpenPulse is not available through Azure Quantum.
Users of IonQ system can use IonQ Native Gates capability through the native gateset setting.
When Rigetti system will be available in Public Preview, customers will be able to use Quil-T — pyQuil 3.1.0 documentation (rigetti.com) in combination with the Azure Quantum provider-specific API: Submit provider-formatted quantum circuits to Azure Quantum using an online notebook.
Hope that helps.
